{"nessus": [{"lastseen": "2023-12-02T15:03:26", "description": "Updated kernel packages that fix two security issues and several bugs are now available for Red Hat Enterprise Linux 5.3 Extended Update Support.\n\nThis update has been rated as having important security impact by the Red Hat Security Response Team.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nThis update includes backported fixes for two security issues. These issues only affected users of Red Hat Enterprise Linux 5.3 Extended Update Support as they have already been addressed for users of Red Hat Enterprise Linux 5 in the 5.4 update, RHSA-2009:1243.\n\nIn accordance with the support policy, future security updates to Red Hat Enterprise Linux 5.3 Extended Update Support will only include issues of critical security impact.\n\nThis update fixes the following security issues :\n\n* it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important)\n\n* a flaw was found in the way the do_sigaltstack() function in the Linux kernel copies the stack_t structure to user-space. On 64-bit machines, this flaw could lead to a four-byte information leak.\n(CVE-2009-2847, Moderate)\n\nThis update also fixes the following bugs :\n\n* a regression was found in the SCSI retry logic: SCSI mode select was not retried when retryable errors were encountered. In Device-Mapper Multipath environments, this could cause paths to fail, or possibly prevent successful failover. (BZ#506905)\n\n* the gcc flag '-fno-delete-null-pointer-checks' was added to the kernel build options. This prevents gcc from optimizing out NULL pointer checks after the first use of a pointer. NULL pointer bugs are often exploited by attackers, and keeping these checks is considered a safety measure. (BZ#515468)\n\n* due to incorrect APIC timer calibration, a system hang could have occurred while booting certain systems. This incorrect timer calibration could have also caused the system time to become faster or slower. With this update, it is still possible for APIC timer calibration issues to occur; however, a clear warning is now provided if they do. (BZ#521237)\n\n* gettimeofday() experienced poor performance (which caused performance problems for applications using gettimeofday()) when running on hypervisors that use hardware assisted virtualization. With this update, MFENCE/LFENCE is used instead of CPUID for gettimeofday() serialization, which resolves this issue. (BZ#523280)\n\nUsers should upgrade to these updated packages, which contain backported patches to correct these issues.

that fix several security issues and several bugs are now available for Red Hat Enterprise Linux 4.\n\nThis update has been rated as having important security impact by the Red Hat Security Response Team.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nThis update fixes the following security issues :\n\n* the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature.\n(CVE-2009-1895, Important)\n\n* it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important)\n\n* Solar Designer reported a missing capability check in the z90crypt driver in the Linux kernel. This missing check could allow a local user with an effective user ID (euid) of 0 to bypass intended capability restrictions. (CVE-2009-1883, Moderate)\n\n* a flaw was found in the way the do_sigaltstack() function in the Linux kernel copies the stack_t structure to user-space. On 64-bit machines, this flaw could lead to a four-byte information leak.\n(CVE-2009-2847, Moderate)\n\nThis update also fixes the following bugs :\n\n* the gcc flag '-fno-delete-null-pointer-checks' was added to the kernel build options.

(BZ#517967)\n\n* a bug in the sky2 driver prevented the phy from being reset properly\non some hardware when it hung, preventing a link from coming back up.\n(BZ#517976)\n\n* disabling MSI-X for qla2xxx also disabled MSI interrupts.\n(BZ#519782)\n\n* performance issues with reads when using the qlge driver on PowerPC\nsystems. A system hang could also occur during reboot. (BZ#519783)\n\n* unreliable time keeping for Red Hat Enterprise Linux virtual\nmachines. The KVM pvclock code is now used to detect/correct lost\nticks. (BZ#520685)\n\n* /proc/cpuinfo was missing flags for new features in supported\nprocessors, possibly preventing the operating system & applications\nfrom getting the best performance. (BZ#520686)\n\n* reading/writing with a serial loopback device on a certain IBM\nsystem did not work unless booted with 'pnpacpi=off'. (BZ#520905)\n\n* mlx4_core failed to load on systems with more than 32 CPUs.\n(BZ#520906)\n\n* on big-endian platforms, interfaces using the mlx4_en driver & Large\nReceive Offload (LRO) did not handle VLAN traffic properly (a\nsegmentation fault in the VLAN stack in the kernel occurred).\n(BZ#520908)\n\n* due to a lock being held for a long time, some systems may have\nexperienced 'BUG: soft lockup' messages under heavy load. (BZ#520919)\n\n* incorrect APIC timer calibration may have caused a system hang\nduring boot, as well as the system time becoming faster or slower. A\nwarning is now provided. (BZ#521238)\n\n* a Fibre Channel device re-scan via 'echo '---' >\n/sys/class/scsi_host/ host[x]/scan' may not complete after hot adding\na drive, leading to soft lockups ('BUG: soft lockup detected').\n(BZ#521239)\n\n* the Broadcom BCM5761 network device could not to be initialized\nproperly; therefore, the associated interface could not obtain an IP\naddress via DHCP or be assigned one manually. (BZ#521241)\n\n* when a process attempted to read from a page that had first been\naccessed by writing to part of it (via write(2)), the NFS client\nneeded to flush the modified portion of the page out to the server, &\nthen read the entire page back in. This flush caused performance\nissues. (BZ#521244)\n\n* a kernel panic when using bnx2x devices & LRO in a bridge. A warning\nis now provided to disable LRO in these situations. (BZ#522636)\n\n* the scsi_dh_rdac driver was updated to recognize the Sun StorageTek\nFlexline 380. (BZ#523237)\n\n* in FIPS mode, random number generators are required to not return\nthe first block of random data they generate, but rather save it to\nseed the repetition check. This update brings the random number\ngenerator into conformance. (BZ#523289)\n\n* an option to disable/enable the use of the first random block is now\nprovided to bring ansi_cprng into compliance with FIPS-140 continuous\ntest requirements. (BZ#523290)\n\n* running the SAP Linux Certification Suite in a KVM guest caused\nsevere SAP kernel errors, causing it to exit. (BZ#524150)\n\n* attempting to 'online' a CPU for a KVM guest via sysfs caused a\nsystem crash. (BZ#524151)\n\n* when using KVM, pvclock returned bogus wallclock values. (BZ#524152)\n\n* the clock could go backwards when using the vsyscall infrastructure.\n(BZ#524527)\n\nSee References for KBase links re BZ#519782 & BZ#520906.\n\nUsers should upgrade to these updated packages, which contain\nbackported patches to correct these issues.

packages that fix security issues, address several hundred bugs and add numerous enhancements are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 5. This is the fourth regular update.\n\nThis update has been rated as having important security impact by the Red Hat Security Response Team.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nThese updated packages fix the following security issues :\n\n* it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important)\n\n* a flaw was found in the way the do_sigaltstack() function in the Linux kernel copies the stack_t structure to user-space. On 64-bit machines, this flaw could lead to a four-byte information leak.\n(CVE-2009-2847, Moderate)\n\n* a flaw was found in the ext4 file system code. A local attacker could use this flaw to cause a denial of service by performing a resize operation on a specially crafted ext4 file system.\n(CVE-2009-0745, Low)\n\n* multiple flaws were found in the ext4 file system code. A local attacker could use these flaws to cause a denial of service by mounting a specially crafted ext4 file system.

If this\npointer points to a writable portion of the memory of the new program,\nthe kernel could corrupt four bytes of memory, possibly leading to a\nlocal denial of service or privilege escalation. (CVE-2009-2848,\nImportant)\n\n* a flaw was found in the way the do_sigaltstack() function in the\nLinux kernel copies the stack_t structure to user-space. On 64-bit\nmachines, this flaw could lead to a four-byte information leak.\n(CVE-2009-2847, Moderate)\n\n* a flaw was found in the ext4 file system code. A local attacker\ncould use this flaw to cause a denial of service by performing a\nresize operation on a specially crafted ext4 file system.\n(CVE-2009-0745, Low)\n\n* multiple flaws were found in the ext4 file system code.

having important security impact by the Red Hat Security Response Team.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity fixes :\n\n* when fput() was called to close a socket, the __scm_destroy() function in the Linux kernel could make indirect recursive calls to itself. This could, potentially, lead to a denial of service issue.\n(CVE-2008-5029, Important)\n\n* the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service. (CVE-2008-5300, Important)\n\n* the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important)\n\n* a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service or code execution. (CVE-2009-1385, Important)\n\n* the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature.\n(CVE-2009-1895, Important)\n\n* it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important)\n\n* missing initialization flaws were found in getname() implementations in the IrDA sockets, AppleTalk DDP protocol, NET/ROM protocol, and ROSE protocol implementations in the Linux kernel. Certain data structures in these getname() implementations were not initialized properly before being copied to user-space. These flaws could lead to an information leak. (CVE-2009-3002, Important)\n\n* a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important)\n\nBug fixes :\n\n* this update adds the mmap_min_addr tunable and restriction checks to help prevent unprivileged users from creating new memory mappings below the minimum address. This can help prevent the exploitation of NULL pointer dereference bugs. Note that mmap_min_addr is set to zero (disabled) by default for backwards compatibility. (BZ#512642)\n\n* a bridge reference count problem in IPv6 has been fixed. (BZ#457010)\n\n* enforce null-termination of user-supplied arguments to setsockopt().\n(BZ#505514)\n\n* the gcc flag '-fno-delete-null-pointer-checks' was added to the kernel build options. This prevents gcc from optimizing out NULL pointer checks after the first use of a pointer. NULL pointer bugs are often exploited by attackers. Keeping these checks is a safety measure. (BZ#511185)\n\n* a check has been added to the IPv4 code to make sure that rt is not NULL, to help prevent future bugs in functions that call ip_append_data() from being exploitable. (BZ#520300)\n\nUsers should upgrade to these updated packages, which contain backported patches to correct these issues.

This could, potentially, lead to a denial of service issue.\n(CVE-2008-5029, Important)\n\n* the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service. (CVE-2008-5300, Important)\n\n* the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important)\n\n* a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service or code execution. (CVE-2009-1385, Important)\n\n* the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature.\n(CVE-2009-1895, Important)\n\n* it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important)\n\n* missing initialization flaws were found in getname() implementations in the IrDA sockets, AppleTalk DDP protocol, NET/ROM protocol, and ROSE protocol implementations in the Linux kernel. Certain data structures in these getname() implementations were not initialized properly before being copied to user-space. These flaws could lead to an information leak. (CVE-2009-3002, Important)\n\n* a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important)\n\nBug fixes :\n\n* this update adds the mmap_min_addr tunable and restriction checks to help prevent unprivileged users from creating new memory mappings below the minimum address. This can help prevent the exploitation of NULL pointer dereference bugs. Note that mmap_min_addr is set to zero (disabled) by default for backwards compatibility.

(BZ#457010)\n\n* enforce null-termination of user-supplied arguments to setsockopt().\n(BZ#505514)\n\n* the gcc flag '-fno-delete-null-pointer-checks' was added to the kernel build options. This prevents gcc from optimizing out NULL pointer checks after the first use of a pointer. NULL pointer bugs are often exploited by attackers. Keeping these checks is a safety measure. (BZ#511185)\n\n* a check has been added to the IPv4 code to make sure that rt is not NULL, to help prevent future bugs in functions that call ip_append_data() from being exploitable.

This could, potentially, lead to a denial of service issue.\n(CVE-2008-5029, Important)\n\n* the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service. (CVE-2008-5300, Important)\n\n* the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important)\n\n* a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service or code execution. (CVE-2009-1385, Important)\n\n* the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature.\n(CVE-2009-1895, Important)\n\n* it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important)\n\n* missing initialization flaws were found in getname() implementations in the IrDA sockets, AppleTalk DDP protocol, NET/ROM protocol, and ROSE protocol implementations in the Linux kernel. Certain data structures in these getname() implementations were not initialized properly before being copied to user-space. These flaws could lead to an information leak. (CVE-2009-3002, Important)\n\n* a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important)\n\nBug fixes :\n\n* this update adds the mmap_min_addr tunable and restriction checks to help prevent unprivileged users from creating new memory mappings below the minimum address. This can help prevent the exploitation of NULL pointer dereference bugs. Note that mmap_min_addr is set to zero (disabled) by default for backwards compatibility. (BZ#512642)\n\n* a bridge reference count problem in IPv6 has been fixed.

This could, potentially, lead to a denial of service issue.\n(CVE-2008-5029, Important)\n\n* the sendmsg() function in the Linux kernel did not block during UNIX\nsocket garbage collection. This could, potentially, lead to a local\ndenial of service. (CVE-2008-5300, Important)\n\n* the exit_notify() function in the Linux kernel did not properly\nreset the exit signal if a process executed a set user ID (setuid)\napplication before exiting. This could allow a local, unprivileged\nuser to elevate their privileges. (CVE-2009-1337, Important)\n\n* a flaw was found in the Intel PRO/1000 network driver in the Linux\nkernel. Frames with sizes near the MTU of an interface may be split\nacross multiple hardware receive descriptors. Receipt of such a frame\ncould leak through a validation check, leading to a corruption of the\nlength check. A remote attacker could use this flaw to send a\nspecially crafted packet that would cause a denial of service or code\nexecution. (CVE-2009-1385, Important)\n\n* the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared\nwhen a setuid or setgid program was executed. A local, unprivileged\nuser could use this flaw to bypass the mmap_min_addr protection\nmechanism and perform a NULL pointer dereference attack, or bypass the\nAddress Space Layout Randomization (ASLR) security feature.\n(CVE-2009-1895, Important)\n\n* it was discovered that, when executing a new process, the\nclear_child_tid pointer in the Linux kernel is not cleared. If this\npointer points to a writable portion of the memory of the new program,\nthe kernel could corrupt four bytes of memory, possibly leading to a\nlocal denial of service or privilege escalation. (CVE-2009-2848,\nImportant)\n\n* missing initialization flaws were found in getname() implementations\nin the IrDA sockets, AppleTalk DDP protocol, NET/ROM protocol, and\nROSE protocol implementations in the Linux kernel. Certain data\nstructures in these getname() implementations were not initialized\nproperly before being copied to user-space. These flaws could lead to\nan information leak. (CVE-2009-3002, Important)\n\n* a NULL pointer dereference flaw was found in each of the following\nfunctions in the Linux kernel: pipe_read_open(), pipe_write_open(),\nand pipe_rdwr_open(). When the mutex lock is not held, the i_pipe\npointer could be released by other processes before it is used to\nupdate the pipe's reader and writer counters. This could lead to a\nlocal denial of service or privilege escalation. (CVE-2009-3547,\nImportant)\n\nBug fixes :\n\n* this update adds the mmap_min_addr tunable and restriction checks to\nhelp prevent unprivileged users from creating new memory mappings\nbelow the minimum address. This can help prevent the exploitation of\nNULL pointer dereference bugs. Note that mmap_min_addr is set to zero\n(disabled) by default for backwards compatibility. (BZ#512642)\n\n* a bridge reference count problem in IPv6 has been fixed. (BZ#457010)\n\n* enforce null-termination of user-supplied arguments to setsockopt().\n(BZ#505514)\n\n* the gcc flag '-fno-delete-null-pointer-checks' was added to the\nkernel build options. This prevents gcc from optimizing out NULL\npointer checks after the first use of a pointer. NULL pointer bugs are\noften exploited by attackers. Keeping these checks is a safety\nmeasure. (BZ#511185)\n\n* a check has been added to the IPv4 code to make sure that rt is not\nNULL, to help prevent future bugs in functions that call\nip_append_data() from being exploitable. (BZ#520300)\n\nUsers should upgrade to these updated packages, which contain\nbackported patches to correct these issues.

having important security impact by the Red Hat Security Response Team.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nThis update fixes the following security issues :\n\n* a system with SELinux enforced was more permissive in allowing local users in the unconfined_t domain to map low memory areas even if the mmap_min_addr restriction was enabled. This could aid in the local exploitation of NULL pointer dereference bugs. (CVE-2009-2695, Important)\n\n* a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open().

This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important)\n\nThis update also fixes the following bugs :\n\n* a caching bug in nfs_readdir() has been resolved. This may have caused parts of directory listings to become stale, as they came from cached data when they should not have, possibly causing NFS clients to see duplicate files or not see all files in a directory. (BZ#526959)\n\n* a bug prevented the pciehp driver from detecting PCI Express hot plug slots on some systems. (BZ#530381)\n\n* when a process attempted to read from a page that had first been accessed by writing to part of it (via write(2)), the NFS client needed to flush the modified portion of the page out to the server, and then read the entire page back in. This flush caused performance issues. (BZ#521243)\n\n* a deadlock was found in the cciss driver. In rare cases, this caused an NMI lockup during boot.

"description": "Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5.\n\nThis update has been rated as having important security impact by the Red Hat Security Response Team.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity fixes :\n\n* a system with SELinux enforced was more permissive in allowing local users in the unconfined_t domain to map low memory areas even if the mmap_min_addr restriction was enabled. This could aid in the local exploitation of NULL pointer dereference bugs. (CVE-2009-2695, Important)\n\n* a NULL pointer dereference flaw was found in the eCryptfs implementation in the Linux kernel. A local attacker could use this flaw to cause a local denial of service or escalate their privileges.\n(CVE-2009-2908, Important)\n\n* a flaw was found in the NFSv4 implementation. The kernel would do an unnecessary permission check after creating a file. This check would usually fail and leave the file with the permission bits set to random values. Note: This is a server-side only issue. (CVE-2009-3286, Important)\n\n* a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important)\n\n* a flaw was found in the Realtek r8169 Ethernet driver in the Linux kernel. pci_unmap_single() presented a memory leak that could lead to IOMMU space exhaustion and a system crash. An attacker on the local network could abuse this flaw by using jumbo frames for large amounts of network traffic. (CVE-2009-3613, Important)\n\n* missing initialization flaws were found in the Linux kernel. Padding data in several core network structures was not initialized properly before being sent to user-space. These flaws could lead to information leaks. (CVE-2009-3228, Moderate)\n\nBug fixes :\n\n* with network bonding in the 'balance-tlb' or 'balance-alb' mode, the primary setting for the primary slave device was lost when said device was brought down. Bringing the slave back up did not restore the primary setting. (BZ#517971)\n\n* some faulty serial device hardware caused systems running the kernel-xen kernel to take a very long time to boot. (BZ#524153)\n\n* a caching bug in nfs_readdir() may have caused NFS clients to see duplicate files or not see all files in a directory. (BZ#526960)\n\n* the RHSA-2009:1243 update removed the mpt_msi_enable option, preventing certain scripts from running. This update adds the option back. (BZ#526963)\n\n* an iptables rule with the recent module and a hit count value greater than the ip_pkt_list_tot parameter (the default is 20), did not have any effect over packets, as the hit count could not be reached. (BZ#527434)\n\n* a check has been added to the IPv4 code to make sure that rt is not NULL, to help prevent future bugs in functions that call ip_append_data() from being exploitable. (BZ#527436)\n\n* a kernel panic occurred in certain conditions after reconfiguring a tape drive's block size. (BZ#528133)\n\n* when using the Linux Virtual Server (LVS) in a master and backup configuration, and propagating active connections on the master to the backup, the connection timeout value on the backup was hard-coded to 180 seconds, meaning connection information on the backup was soon lost. This could prevent the successful failover of connections. The timeout value can now be set via 'ipvsadm --set'. (BZ#528645)\n\n* a bug in nfs4_do_open_expired() could have caused the reclaimer thread on an NFSv4 client to enter an infinite loop. (BZ#529162)\n\n* MSI interrupts may not have been delivered for r8169 based network cards that have MSI interrupts enabled. This bug only affected certain systems. (BZ#529366)\n\nUsers should upgrade to these updated packages, which contain backported patches to correct these issues.

This could aid in the local\nexploitation of NULL pointer dereference bugs. (CVE-2009-2695,\nImportant)\n\n* a NULL pointer dereference flaw was found in the eCryptfs\nimplementation in the Linux kernel. A local attacker could use this\nflaw to cause a local denial of service or escalate their privileges.\n(CVE-2009-2908, Important)\n\n* a flaw was found in the NFSv4 implementation. The kernel would do an\nunnecessary permission check after creating a file. This check would\nusually fail and leave the file with the permission bits set to random\nvalues. Note: This is a server-side only issue. (CVE-2009-3286,\nImportant)\n\n* a NULL pointer dereference flaw was found in each of the following\nfunctions in the Linux kernel: pipe_read_open(), pipe_write_open(),\nand pipe_rdwr_open(). When the mutex lock is not held, the i_pipe\npointer could be released by other processes before it is used to\nupdate the pipe's reader and writer counters. This could lead to a\nlocal denial of service or privilege escalation. (CVE-2009-3547,\nImportant)\n\n* a flaw was found in the Realtek r8169 Ethernet driver in the Linux\nkernel. pci_unmap_single() presented a memory leak that could lead to\nIOMMU space exhaustion and a system crash. An attacker on the local\nnetwork could abuse this flaw by using jumbo frames for large amounts\nof network traffic. (CVE-2009-3613, Important)\n\n* missing initialization flaws were found in the Linux kernel. Padding\ndata in several core network structures was not initialized properly\nbefore being sent to user-space. These flaws could lead to information\nleaks. (CVE-2009-3228, Moderate)\n\nBug fixes :\n\n* with network bonding in the 'balance-tlb' or 'balance-alb' mode, the\nprimary setting for the primary slave device was lost when said device\nwas brought down. Bringing the slave back up did not restore the\nprimary setting. (BZ#517971)\n\n* some faulty serial device hardware caused systems running the\nkernel-xen kernel to take a very long time to boot. (BZ#524153)\n\n* a caching bug in nfs_readdir() may have caused NFS clients to see\nduplicate files or not see all files in a directory. (BZ#526960)\n\n* the RHSA-2009:1243 update removed the mpt_msi_enable option,\npreventing certain scripts from running. This update adds the option\nback. (BZ#526963)\n\n* an iptables rule with the recent module and a hit count value\ngreater than the ip_pkt_list_tot parameter (the default is 20), did\nnot have any effect over packets, as the hit count could not be\nreached. (BZ#527434)\n\n* a check has been added to the IPv4 code to make sure that rt is not\nNULL, to help prevent future bugs in functions that call\nip_append_data() from being exploitable. (BZ#527436)\n\n* a kernel panic occurred in certain conditions after reconfiguring a\ntape drive's block size. (BZ#528133)\n\n* when using the Linux Virtual Server (LVS) in a master and backup\nconfiguration, and propagating active connections on the master to the\nbackup, the connection timeout value on the backup was hard-coded to\n180 seconds, meaning connection information on the backup was soon\nlost. This could prevent the successful failover of connections. The\ntimeout value can now be set via 'ipvsadm --set'. (BZ#528645)\n\n* a bug in nfs4_do_open_expired() could have caused the reclaimer\nthread on an NFSv4 client to enter an infinite loop. (BZ#529162)\n\n* MSI interrupts may not have been delivered for r8169 based network\ncards that have MSI interrupts enabled. This bug only affected certain\nsystems. (BZ#529366)\n\nUsers should upgrade to these updated packages, which contain\nbackported patches to correct these issues.

This could aid in the local exploitation of NULL pointer dereference bugs. (CVE-2009-2695, Important)\n\n - a NULL pointer dereference flaw was found in the eCryptfs implementation in the Linux kernel. A local attacker could use this flaw to cause a local denial of service or escalate their privileges. (CVE-2009-2908, Important)\n\n - a flaw was found in the NFSv4 implementation. The kernel would do an unnecessary permission check after creating a file. This check would usually fail and leave the file with the permission bits set to random values. Note:\n This is a server-side only issue. (CVE-2009-3286, Important)\n\n - a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel:\n pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important)\n\n - a flaw was found in the Realtek r8169 Ethernet driver in the Linux kernel. pci_unmap_single() presented a memory leak that could lead to IOMMU space exhaustion and a system crash. An attacker on the local network could abuse this flaw by using jumbo frames for large amounts of network traffic. (CVE-2009-3613, Important)\n\n - missing initialization flaws were found in the Linux kernel. Padding data in several core network structures was not initialized properly before being sent to user-space. These flaws could lead to information leaks.\n (CVE-2009-3228, Moderate)\n\nBug fixes :\n\n - with network bonding in the 'balance-tlb' or 'balance-alb' mode, the primary setting for the primary slave device was lost when said device was brought down.\n Bringing the slave back up did not restore the primary setting. (BZ#517971)\n\n - some faulty serial device hardware caused systems running the kernel-xen kernel to take a very long time to boot. (BZ#524153)\n\n - a caching bug in nfs_readdir() may have caused NFS clients to see duplicate files or not see all files in a directory. (BZ#526960)\n\n - the RHSA-2009:1243 update removed the mpt_msi_enable option, preventing certain scripts from running. This update adds the option back. (BZ#526963)\n\n - an iptables rule with the recent module and a hit count value greater than the ip_pkt_list_tot parameter (the default is 20), did not have any effect over packets, as the hit count could not be reached. (BZ#527434)\n\n - a check has been added to the IPv4 code to make sure that rt is not NULL, to help prevent future bugs in functions that call ip_append_data() from being exploitable. (BZ#527436)\n\n - a kernel panic occurred in certain conditions after reconfiguring a tape drive's block size. (BZ#528133)\n\n - when using the Linux Virtual Server (LVS) in a master and backup configuration, and propagating active connections on the master to the backup, the connection timeout value on the backup was hard-coded to 180 seconds, meaning connection information on the backup was soon lost. This could prevent the successful failover of connections. The timeout value can now be set via 'ipvsadm --set'. (BZ#528645)\n\n - a bug in nfs4_do_open_expired() could have caused the reclaimer thread on an NFSv4 client to enter an infinite loop. (BZ#529162)\n\n - MSI interrupts may not have been delivered for r8169 based network cards that have MSI interrupts enabled.\n This bug only affected certain systems.

This could,potentially, lead to a denial of service issue.\n (CVE-2008-5029, Important)\n\n - the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service.\n (CVE-2008-5300, Important)\n\n - the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important)\n\n - a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service or code execution. (CVE-2009-1385, Important)\n\n - the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature.\n (CVE-2009-1895, Important)\n\n - it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared.

The Common Vulnerabilities and Exposures project identifies the following problems :\n\n - CVE-2009-2695 Eric Paris provided several fixes to increase the protection provided by the mmap_min_addr tunable against NULL pointer dereference vulnerabilities.\n\n - CVE-2009-2903 Mark Smith discovered a memory leak in the appletalk implementation. When the appletalk and ipddp modules are loaded, but no ipddp'N' device is found, remote attackers can cause a denial of service by consuming large amounts of system memory.\n\n - CVE-2009-2908 Loic Minier discovered an issue in the eCryptfs filesystem. A local user can cause a denial of service (kernel oops) by causing a dentry value to go negative.\n\n - CVE-2009-2909 Arjan van de Ven discovered an issue in the AX.25 protocol implementation. A specially crafted call to setsockopt() can result in a denial of service (kernel oops).\n\n - CVE-2009-2910 Jan Beulich discovered the existence of a sensitive kernel memory leak. Systems running the 'amd64' kernel do not properly sanitize registers for 32-bit processes.\n\n - CVE-2009-3001 Jiri Slaby fixed a sensitive memory leak issue in the ANSI/IEEE 802.2 LLC implementation. This is not exploitable in the Debian lenny kernel as root privileges are required to exploit this issue.\n\n - CVE-2009-3002 Eric Dumazet fixed several sensitive memory leaks in the IrDA, X.25 PLP (Rose), NET/ROM, Acorn Econet/AUN, and Controller Area Network (CAN) implementations.

This change\nwill add an additional safeguard against a class of security\nvulnerabilities known as 'NULL pointer dereference' vulnerabilities,\nbut it will need to be overridden when using certain applications.\nAdditional information about this change, including instructions for\nmaking this change locally in advance of 5.0.4 (recommended), can be\nfound at: https://wiki.debian.org/mmap_min_addr.\n\nSeveral vulnerabilities have been discovered in the Linux kernel that\nmay lead to a denial of service, sensitive memory leak or privilege\nescalation. The Common Vulnerabilities and Exposures project\nidentifies the following problems :\n\n - CVE-2009-2695\n Eric Paris provided several fixes to increase the\n protection provided by the mmap_min_addr tunable against\n NULL pointer dereference vulnerabilities.\n\n - CVE-2009-2903\n Mark Smith discovered a memory leak in the appletalk\n implementation. When the appletalk and ipddp modules are\n loaded, but no ipddp'N' device is found, remote\n attackers can cause a denial of service by consuming\n large amounts of system memory.\n\n - CVE-2009-2908\n Loic Minier discovered an issue in the eCryptfs\n filesystem. A local user can cause a denial of service\n (kernel oops) by causing a dentry value to go negative.\n\n - CVE-2009-2909\n Arjan van de Ven discovered an issue in the AX.25\n protocol implementation. A specially crafted call to\n setsockopt() can result in a denial of service (kernel\n oops).\n\n - CVE-2009-2910\n Jan Beulich discovered the existence of a sensitive\n kernel memory leak. Systems running the 'amd64' kernel\n do not properly sanitize registers for 32-bit processes.\n\n - CVE-2009-3001\n Jiri Slaby fixed a sensitive memory leak issue in the\n ANSI/IEEE 802.2 LLC implementation. This is not\n exploitable in the Debian lenny kernel as root\n privileges are required to exploit this issue.\n\n - CVE-2009-3002\n Eric Dumazet fixed several sensitive memory leaks in the\n IrDA, X.25 PLP (Rose), NET/ROM, Acorn Econet/AUN, and\n Controller Area Network (CAN) implementations. Local\n users can exploit these issues to gain access to kernel\n memory.\n\n - CVE-2009-3286\n Eric Paris discovered an issue with the NFSv4 server\n implementation. When an O_EXCL create fails, files may\n be left with corrupted permissions, possibly granting\n unintentional privileges to other local users.\n\n - CVE-2009-3290\n Jan Kiszka noticed that the kvm_emulate_hypercall\n function in KVM does not prevent access to MMU\n hypercalls from ring 0, which allows local guest OS\n users to cause a denial of service (guest kernel crash)\n and read or write guest kernel memory.\n\n - CVE-2009-3613\n Alistair Strachan reported an issue in the r8169 driver.\n Remote users can cause a denial of service (IOMMU space\n exhaustion and system crash) by transmitting a large\n amount of jumbo frames.\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://wiki.debian.org/mmap_min_addr\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2009-2695\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2009-2903\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2009-2908\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2009-2909\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2009-2910\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2009-3001\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2009-3002\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2009-3286\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2009-3290\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2009-3613\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://www.debian.org/security/2009/dsa-1915\"\n );\n script_set_attribute(\n attribute:\"solution\", \n value:\n\"Upgrade the linux-2.6 and user-mode-linux packages.\n\nFor the oldstable distribution (etch), these problems, where\napplicable, will be fixed in updates to linux-2.6 and linux-2.6.24.\n\nFor the stable distribution (lenny), this problem has been fixed in\nversion 2.6.26-19lenny1.\n\nNote: Debian carefully tracks all known security issues across every\nlinux kernel package in all releases under active security support.\nHowever, given the high frequency at which low-severity security\nissues are discovered in the kernel and the resource requirements of\ndoing an update, updates for lower priority issues will normally not\nbe released for all kernels at the same time.

programming library for color text mode, widget based user interfaces. Newt can be used to add stacked windows, entry widgets, checkboxes, radio buttons, labels, plain text fields, scrollbars, etc., to text mode user interfaces.\n\n A heap-based buffer overflow flaw was found in the way newt processes content that is to be displayed in a text dialog box.\n A local attacker could issue a specially crafted text dialog box display request (direct or via a custom application), leading to a denial of service (application crash) or, potentially, arbitrary code execution with the privileges of the user running the application using the newt library.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-2905 to this issue.\n\nb. vMA and Service Console update for vMA package nfs-utils to 1.0.9-42.el5\n\n The nfs-utils package provides a daemon for the kernel NFS server and related tools.\n\n It was discovered that nfs-utils did not use tcp_wrappers correctly. Certain hosts access rules defined in '/etc/hosts.allow' and '/etc/hosts.deny' may not have been honored, possibly allowing remote attackers to bypass intended access restrictions.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2008-4552 to this issue.\n\nc. vMA and Service Console package glib2 updated to 2.12.3-4.el5_3.1\n\n GLib is the low-level core library that forms the basis for projects such as GTK+ and GNOME. It provides data structure handling for C, portability wrappers, and interfaces for such runtime functionality as an event loop, threads, dynamic loading, and an object system.\n\n Multiple integer overflows in glib/gbase64.c in GLib before 2.20 allow context-dependent attackers to execute arbitrary code via a long string that is converted either from or to a base64 representation.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2008-4316 to this issue.\n\nd. vMA and Service Console update for openssl to 0.9.8e-12.el5\n\n SSL is a toolkit implementing SSL v2/v3 and TLS protocols with full- strength cryptography world-wide.\n\n Multiple denial of service flaws were discovered in OpenSSL's DTLS implementation. A remote attacker could use these flaws to cause a DTLS server to use excessive amounts of memory, or crash on an invalid memory access or NULL pointer dereference.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the names CVE-2009-1377, CVE-2009-1378, CVE-2009-1379, CVE-2009-1386, CVE-2009-1387 to these issues.\n\n An input validation flaw was found in the handling of the BMPString and UniversalString ASN1 string types in OpenSSL's ASN1_STRING_print_ex() function. An attacker could use this flaw to create a specially crafted X.509 certificate that could cause applications using the affected function to crash when printing certificate contents.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-0590 to this issue.\n\ne. vMA and Service Console package bind updated to 9.3.6-4.P1.el5_4.1\n\n It was discovered that BIND was incorrectly caching responses without performing proper DNSSEC validation, when those responses were received during the resolution of a recursive client query that requested DNSSEC records but indicated that checking should be disabled. A remote attacker could use this flaw to bypass the DNSSEC validation check and perform a cache poisoning attack if the target BIND server was receiving such client queries.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-4022 to this issue.\n\nf. vMA and Service Console package expat updated to 1.95.8-8.3.el5_4.2.\n\n Two buffer over-read flaws were found in the way Expat handled malformed UTF-8 sequences when processing XML files. A specially- crafted XML file could cause applications using Expat to fail while parsing the file.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the names CVE-2009-3560 and CVE-2009-3720 to these issues.\n\ng. vMA and Service Console package openssh update to 4.3p2-36.el5_4.2\n\n A Red Hat specific patch used in the openssh packages as shipped in Red Hat Enterprise Linux 5.4 (RHSA-2009:1287) loosened certain ownership requirements for directories used as arguments for the ChrootDirectory configuration options. A malicious user that also has or previously had non-chroot shell access to a system could possibly use this flaw to escalate their privileges and run commands as any system user.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-2904 to this issue.\n\nh. vMA and Service Console package ntp updated to ntp-4.2.2p1-9.el5_4.1.i386.rpm\n\n A flaw was discovered in the way ntpd handled certain malformed NTP packets. ntpd logged information about all such packets and replied with an NTP packet that was treated as malformed when received by another ntpd. A remote attacker could use this flaw to create an NTP packet reply loop between two ntpd servers through a malformed packet with a spoofed source IP address and port, causing ntpd on those servers to use excessive amounts of CPU time and fill disk space with log messages.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-3563 to this issue. \n\ni. vMA update for package kernel to 2.6.18-164.9.1.el5\n\n Updated vMA package kernel addresses the security issues listed below.\n\n The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-2849 to the security issue fixed in kernel 2.6.18-128.2.1\n\n The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2009-2695, CVE-2009-2908, CVE-2009-3228, CVE-2009-3286, CVE-2009-3547, CVE-2009-3613 to the security issues fixed in kernel 2.6.18-128.6.1\n\n The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2009-3612, CVE-2009-3620, CVE-2009-3621, CVE-2009-3726 to the security issues fixed in kernel 2.6.18-128.9.1\n\nj. vMA 4.0 updates for the packages kpartx, libvolume-id, device-mapper-multipath, fipscheck, dbus, dbus-libs, and ed\n\n kpartx updated to 0.4.7-23.el5_3.4, libvolume-id updated to 095-14.20.el5 device-mapper-multipath package updated to 0.4.7-23.el5_3.4, fipscheck updated to 1.0.3-1.el5, dbus updated to 1.1.2-12.el5, dbus-libs updated to 1.1.2-12.el5, and ed package updated to 0.2-39.el5_2.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the names CVE-2008-3916, CVE-2009-1189 and CVE-2009-0115 to these issues.", "cvss3": {}, "published": "2010-03-05T00:00:00", "type": "nessus", "title": "VMSA-2010-0004 : ESX Service Console and vMA third-party updates", "bulletinFamily": "scanner", "cvss2": {}, "cvelist": ["CVE-2008-3916", "CVE-2008-4316", "CVE-2008-4552", "CVE-2009-0115", "CVE-2009-0590", "CVE-2009-1189", "CVE-2009-1377", "CVE-2009-1378", "CVE-2009-1379", "CVE-2009-1386", "CVE-2009-1387", "CVE-2009-2695", "CVE-2009-2849", "CVE-2009-2904", "CVE-2009-2905", "CVE-2009-2908", "CVE-2009-3228", "CVE-2009-3286", "CVE-2009-3547", "CVE-2009-3560", "CVE-2009-3563", "CVE-2009-3612", "CVE-2009-3613", "CVE-2009-3620", "CVE-2009-3621", "CVE-2009-3720", "CVE-2009-3726", "CVE-2009-4022"], "modified": "2021-01-06T00:00:00", "cpe": ["cpe:/o:vmware:esx:3.5", "cpe:/o:vmware:esx:4.0"], "id": "VMWARE_VMSA-2010-0004.NASL", "href": "https://www.tenable.com/plugins/nessus/44993", "sourceData": "#%NASL_MIN_LEVEL 70300\n#\n# (C) Tenable Network Security, Inc.\n#\n# The descriptive text and package checks in this plugin were \n# extracted from VMware Security Advisory 2010-0004. \n# The text itself is copyright (C) VMware Inc.\n#\n\ninclude('deprecated_nasl_level.inc');\ninclude('compat.inc');\n\nif (description)\n{\n script_id(44993);\n script_version(\"1.33\");\n script_set_attribute(attribute:\"plugin_modification_date\", value:\"2021/01/06\");\n\n script_cve_id(\"CVE-2008-3916\", \"CVE-2008-4316\", \"CVE-2008-4552\", \"CVE-2009-0115\", \"CVE-2009-0590\", \"CVE-2009-1189\", \"CVE-2009-1377\", \"CVE-2009-1378\", \"CVE-2009-1379\", \"CVE-2009-1386\", \"CVE-2009-1387\", \"CVE-2009-2695\", \"CVE-2009-2849\", \"CVE-2009-2904\", \"CVE-2009-2905\", \"CVE-2009-2908\", \"CVE-2009-3228\", \"CVE-2009-3286\", \"CVE-2009-3547\", \"CVE-2009-3560\", \"CVE-2009-3563\", \"CVE-2009-3612\", \"CVE-2009-3613\", \"CVE-2009-3620\", \"CVE-2009-3621\", \"CVE-2009-3720\", \"CVE-2009-3726\", \"CVE-2009-4022\");\n script_bugtraq_id(30815, 31602, 31823, 34100, 34256, 35001, 35138, 35174, 36304, 36515, 36552, 36639, 36706, 36723, 36824, 36827, 36901, 36936, 37118, 37203, 37255);\n script_xref(name:\"VMSA\", value:\"2010-0004\");\n\n script_name(english:\"VMSA-2010-0004 : ESX Service Console and vMA third-party updates\");\n script_summary(english:\"Checks esxupdate output for the patches\");\n\n script_set_attribute(\n attribute:\"synopsis\",\n value:\n\"The remote VMware ESX host is missing one or more security-related\npatches.\"\n );\n script_set_attribute(\n attribute:\"description\",\n value:\n\"a. vMA and Service Console update for newt to 0.52.2-12.el5_4.1\n\n Newt is a programming library for color text mode, widget based\n user interfaces.

The kernel in Moblin 2.0 uses NULL ptr protection which avoids code execution possbilities.\n\nCVE-2009-2903: Memory leak in the appletalk subsystem in the Linux kernel 2.4.x through 2.4.37.6 and 2.6.x through 2.6.31, when the appletalk and ipddp modules are loaded but the ipddp'N' device is not found, allows remote attackers to cause a denial of service (memory consumption) via IP-DDP datagrams.\n\nCVE-2009-3621: net/unix/af_unix.c in the Linux kernel 2.6.31.4 and earlier allows local users to cause a denial of service (system hang) by creating an abstract-namespace AF_UNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket.\n\nCVE-2009-3612: The tcf_fill_node function in net/sched/cls_api.c in the netlink subsystem in the Linux kernel 2.6.x before 2.6.32-rc5, and 2.4.37.6 and earlier, does not initialize a certain tcm__pad2 structure member, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors.\n\nCVE-2009-3620: The ATI Rage 128 (aka r128) driver in the Linux kernel before 2.6.31-git11 does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls.\n\nCVE-2009-3726: The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state.\n\nCVE-2009-3286: NFSv4 in the Linux kernel 2.6.18, and possibly other versions, does not properly clean up an inode when an O_EXCL create fails, which causes files to be created with insecure settings such as setuid bits, and possibly allows local users to gain privileges, related to the execution of the do_open_permission function even when a create fails.\n\nCVE-2009-2910: arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.31.4 on the x86_64 platform does not clear certain kernel registers before a return to user mode, which allows local users to read register values from an earlier process by switching an ia32 process to 64-bit mode.\n\nCVE-2009-3238: The get_random_int function in drivers/char/random.c in the Linux kernel before 2.6.30 produces insufficiently random numbers, which allows attackers to predict the return value, and possibly defeat protection mechanisms based on randomization, via vectors that leverage the function's tendency to 'return the same value over and over again for long stretches of time.'\n\nCVE-2009-2848: The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit.\n\nCVE-2009-3002: The Linux kernel before 2.6.31-rc7 does not initialize certain data structures within getname functions, which allows local users to read the contents of some kernel memory locations by calling getsockname on (1) an AF_APPLETALK socket, related to the atalk_getname function in net/appletalk/ddp.c; (2) an AF_IRDA socket, related to the irda_getname function in net/irda/af_irda.c; (3) an AF_ECONET socket, related to the econet_getname function in net/econet/af_econet.c; (4) an AF_NETROM socket, related to the nr_getname function in net/netrom/af_netrom.c; (5) an AF_ROSE socket, related to the rose_getname function in net/rose/af_rose.c; or (6) a raw CAN socket, related to the raw_getname function in net/can/raw.c.\n\nCVE-2009-1633: Multiple buffer overflows in the cifs subsystem in the Linux kernel before 2.6.29.4 allow remote CIFS servers to cause a denial of service (memory corruption) and possibly have unspecified other impact via (1) a malformed Unicode string, related to Unicode string area alignment in fs/cifs/sess.c; or (2) long Unicode characters, related to fs/cifs/cifssmb.c and

dereference and system crash) or possibly\nhave unknown other impact via an unspecified ioctl associated with\nreceiving an ISO packet that contains zero in the payload-length\nfield.\n\nCVE-2009-4308: The ext4_decode_error function in fs/ext4/super.c in\nthe ext4 filesystem in the Linux kernel before 2.6.32 allows\nuser-assisted remote attackers to cause a denial of service (NULL\npointer dereference), and possibly have unspecified other impact, via\na crafted read-only filesystem that lacks a journal.\n\nCVE-2009-3939: The poll_mode_io file for the megaraid_sas driver in\nthe Linux kernel 2.6.31.6 and earlier has world-writable permissions,\nwhich allows local users to change the I/O mode of the driver by\nmodifying this file.\n\nCVE-2009-4021: The fuse_direct_io function in fs/fuse/file.c in the\nfuse subsystem in the Linux kernel before 2.6.32-rc7 might allow\nattackers to cause a denial of service (invalid pointer dereference\nand OOPS) via vectors possibly related to a memory-consumption attack.\n\nCVE-2009-3547: A race condition in the pipe(2) systemcall could be\nused by local attackers to hang the machine. The kernel in Moblin 2.0\nuses NULL ptr protection which avoids code execution possbilities.\n\nCVE-2009-2903: Memory leak in the appletalk subsystem in the Linux\nkernel 2.4.x through 2.4.37.6 and 2.6.x through 2.6.31, when the\nappletalk and ipddp modules are loaded but the ipddp'N' device is not\nfound, allows remote attackers to cause a denial of service (memory\nconsumption) via IP-DDP datagrams.\n\nCVE-2009-3621: net/unix/af_unix.c in the Linux kernel 2.6.31.4 and\nearlier allows local users to cause a denial of service (system hang)\nby creating an abstract-namespace AF_UNIX listening socket, performing\na shutdown operation on this socket, and then performing a series of\nconnect operations to this socket.\n\nCVE-2009-3612: The tcf_fill_node function in net/sched/cls_api.c in\nthe netlink subsystem in the Linux kernel 2.6.x before 2.6.32-rc5, and\n2.4.37.6 and earlier, does not initialize a certain tcm__pad2\nstructure member, which might allow local users to obtain sensitive\ninformation from kernel memory via unspecified vectors.\n\nCVE-2009-3620: The ATI Rage 128 (aka r128) driver in the Linux kernel\nbefore 2.6.31-git11 does not properly verify Concurrent Command Engine\n(CCE) state initialization, which allows local users to cause a denial\nof service (NULL pointer dereference and system crash) or possibly\ngain privileges via unspecified ioctl calls.\n\nCVE-2009-3726: The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the\nNFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS\nservers to cause a denial of service (NULL pointer dereference and\npanic) by sending a certain response containing incorrect file\nattributes, which trigger attempted use of an open file that lacks\nNFSv4 state.\n\nCVE-2009-3286: NFSv4 in the Linux kernel 2.6.18, and possibly other\nversions, does not properly clean up an inode when an O_EXCL create\nfails, which causes files to be created with insecure settings such as\nsetuid bits, and possibly allows local users to gain privileges,\nrelated to the execution of the do_open_permission function even when\na create fails.\n\nCVE-2009-2910: arch/x86/ia32/ia32entry.S in the Linux kernel before\n2.6.31.4 on the x86_64 platform does not clear certain kernel\nregisters before a return to user mode, which allows local users to\nread register values from an earlier process by switching an ia32\nprocess to 64-bit mode.\n\nCVE-2009-3238: The get_random_int function in drivers/char/random.c in\nthe Linux kernel before 2.6.30 produces insufficiently random numbers,\nwhich allows attackers to predict the return value, and possibly\ndefeat protection mechanisms based on randomization, via vectors that\nleverage the function's tendency to 'return the same value over and\nover again for long stretches of time.'\n\nCVE-2009-2848: The execve function in the Linux kernel, possibly\n2.6.30-rc6 and earlier, does not properly clear the\ncurrent->clear_child_tid pointer, which allows local users to cause a\ndenial of service (memory corruption) or possibly gain privileges via\na clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID\nenabled, which is not properly handled during thread creation and\nexit.\n\nCVE-2009-3002: The Linux kernel before 2.6.31-rc7 does not initialize\ncertain data structures within getname functions, which allows local\nusers to read the contents of some kernel memory locations by calling\ngetsockname on (1) an AF_APPLETALK socket, related to the\natalk_getname function in net/appletalk/ddp.c; (2) an AF_IRDA socket,\nrelated to the irda_getname function in net/irda/af_irda.c; (3) an\nAF_ECONET socket, related to the econet_getname function in\nnet/econet/af_econet.c; (4) an AF_NETROM socket, related to the\nnr_getname function in net/netrom/af_netrom.c; (5) an AF_ROSE socket,\nrelated to the rose_getname function in net/rose/af_rose.c; or (6) a\nraw CAN socket, related to the raw_getname function in net/can/raw.c.\n\nCVE-2009-1633: Multiple buffer overflows in the cifs subsystem in the\nLinux kernel before 2.6.29.4 allow remote CIFS servers to cause a\ndenial of service (memory corruption) and possibly have unspecified\nother impact via (1) a malformed Unicode string, related to Unicode\nstring area alignment in fs/cifs/sess.c; or (2) long Unicode\ncharacters, related to fs/cifs/cifssmb.c and the cifs_readdir function\nin fs/cifs/readdir.c.\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n

Service Console package openssl updated to 0.9.8e-12.el5_4.1\n\n OpenSSL is a toolkit implementing SSL v2/v3 and TLS protocols with full-strength cryptography world-wide.\n\n A memory leak in the zlib could allow a remote attacker to cause a denial of service (memory consumption) via vectors that trigger incorrect calls to the CRYPTO_cleanup_all_ex_data function.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-4355 to this issue.\n\n A vulnerability was discovered which may allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash collision in less than brute-force time. NOTE: the scope of this issue is currently limited because the amount of computation required is still large.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-2409 to this issue.\n\n This update also includes security fixes that were first addressed in version openssl-0.9.8e-12.el5.i386.rpm.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the names CVE-2009-0590, CVE-2009-1377, CVE-2009-1378, CVE-2009-1379, CVE-2009-1386 and CVE-2009-1387 to these issues.\n\nd. Service Console update for krb5 to 1.6.1-36.el5_4.1 and pam_krb5 to 2.2.14-15.\n\n Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography.\n\n Multiple integer underflows in the AES and RC4 functionality in the crypto library could allow remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code by providing ciphertext with a length that is too short to be valid.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-4212 to this issue.\n\n The service console package for pam_krb5 is updated to version pam_krb5-2.2.14-15. This update fixes a flaw found in pam_krb5. In some non-default configurations (specifically, where pam_krb5 would be the first module to prompt for a password), a remote attacker could use this flaw to recognize valid usernames, which would aid a dictionary-based password guess attack.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-1384 to this issue.\n\ne. Service Console package bind updated to 9.3.6-4.P1.el5_4.2\n\n BIND (Berkeley Internet Name Daemon) is by far the most widely used Domain Name System (DNS) software on the Internet.\n\n A vulnerability was discovered which could allow remote attacker to add the Authenticated Data (AD) flag to a forged NXDOMAIN response for an existing domain.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0097 to this issue.\n\n A vulnerability was discovered which could allow remote attackers to conduct DNS cache poisoning attacks by receiving a recursive client query and sending a response that contains CNAME or DNAME records, which do not have the intended validation before caching.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0290 to this issue.\n\n A vulnerability was found in the way that bind handles out-of- bailiwick data accompanying a secure response without re-fetching from the original source, which could allow remote attackers to have an unspecified impact via a crafted response.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0382 to this issue.\n\n NOTE: ESX does not use the BIND name service daemon by default.\n\nf. Service Console package gcc updated to 3.2.3-60\n\n The GNU Compiler Collection includes front ends for C, C++, Objective-C, Fortran, Java, and Ada, as well as libraries for these languages\n\n GNU Libtool's ltdl.c attempts to open .la library files in the current working directory. This could allow a local user to gain privileges via a Trojan horse file. The GNU C Compiler collection (gcc) provided in ESX contains a statically linked version of the vulnerable code, and is being replaced.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-3736 to this issue.\n\ng. Service Console package gzip update to 1.3.3-15.rhel3\n\n gzip is a software application used for file compression\n\n An integer underflow in gzip's unlzw function on 64-bit platforms may allow a remote attacker to trigger an array index error leading to a denial of service (application crash) or possibly execute arbitrary code via a crafted LZW compressed file.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0001 to this issue.\n\nh. Service Console package sudo updated to 1.6.9p17-6.el5_4\n\n Sudo (su 'do') allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments.\n\n When a pseudo-command is enabled, sudo permits a match between the name of the pseudo-command and the name of an executable file in an arbitrary directory, which allows local users to gain privileges via a crafted executable file.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0426 to this issue.\n\n When the runas_default option is used, sudo does not properly set group memberships, which allows local users to gain privileges via a sudo command.\n\n The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0427 to this issue.", "cvss3": {}, "published": "2010-06-01T00:00:00", "type": "nessus", "title": "VMSA-2010-0009 : ESXi ntp and ESX Service Console third-party updates", "bulletinFamily": "scanner", "cvss2": {}, "cvelist": ["CVE-2006-6304", "CVE-2007-4567", "CVE-2009-0590", "CVE-2009-1377", "CVE-2009-1378", "CVE-2009-1379", "CVE-2009-1384", "CVE-2009-1386", "CVE-2009-1387", "CVE-2009-2409", "CVE-2009-2695", "CVE-2009-2908", "CVE-2009-2910", "CVE-2009-3080", "CVE-2009-3228", "CVE-2009-3286", "CVE-2009-3547", "CVE-2009-3556", "CVE-2009-3563", "CVE-2009-3612", "CVE-2009-3613", "CVE-2009-3620", "CVE-2009-3621", "CVE-2009-3726", "CVE-2009-3736", "CVE-2009-3889", "CVE-2009-3939", "CVE-2009-4020", "CVE-2009-4021", "CVE-2009-4138", "CVE-2009-4141", "CVE-2009-4212", "CVE-2009-4272", "CVE-2009-4355", "CVE-2009-4536", "CVE-2009-4537", "CVE-2009-4538", "CVE-2010-0001", "CVE-2010-0097", "CVE-2010-0290", "CVE-2010-0382", "CVE-2010-0426", "CVE-2010-0427"], "modified": "2021-01-06T00:00:00", "cpe": ["cpe:/o:vmware:esx:3.5", "cpe:/o:vmware:esx:4.0", "cpe:/o:vmware:esxi:4.0"], "id": "VMWARE_VMSA-2010-0009.NASL", "href": "https://www.tenable.com/plugins/nessus/46765", "sourceData": "#%NASL_MIN_LEVEL 70300\n#\n# (C) Tenable Network Security, Inc.\n#\n# The descriptive text and package checks in this plugin were \n# extracted from VMware Security Advisory 2010-0009. \n# The text itself is copyright (C) VMware Inc.\n#\n\ninclude('deprecated_nasl_level.inc');\ninclude('compat.inc');\n\nif (description)\n{\n script_id(46765);\n script_version(\"1.45\");\n script_set_attribute(attribute:\"plugin_modification_date\", value:\"2021/01/06\");\n\n script_cve_id(\"CVE-2006-6304\", \"CVE-2007-4567\", \"CVE-2009-0590\", \"CVE-2009-1377\", \"CVE-2009-1378\", \"CVE-2009-1379\", \"CVE-2009-1384\", \"CVE-2009-1386\", \"CVE-2009-1387\", \"CVE-2009-2409\", \"CVE-2009-2695\", \"CVE-2009-2908\", \"CVE-2009-2910\", \"CVE-2009-3080\", \"CVE-2009-3228\", \"CVE-2009-3286\", \"CVE-2009-3547\", \"CVE-2009-3556\", \"CVE-2009-3563\", \"CVE-2009-3612\", \"CVE-2009-3613\", \"CVE-2009-3620\", \"CVE-2009-3621\", \"CVE-2009-3726\", \"CVE-2009-3736\", \"CVE-2009-3889\", \"CVE-2009-3939\", \"CVE-2009-4020\", \"CVE-2009-4021\", \"CVE-2009-4138\", \"CVE-2009-4141\", \"CVE-2009-4212\", \"CVE-2009-4272\", \"CVE-2009-4355\", \"CVE-2009-4536\", \"CVE-2009-4537\", \"CVE-2009-4538\", \"CVE-2010-0001\", \"CVE-2010-0097\", \"CVE-2010-0290\", \"CVE-2010-0382\", \"CVE-2010-0426\", \"CVE-2010-0427\");\n script_bugtraq_id(31692, 34256, 35001, 35112, 35138, 35174, 35417, 36304, 36472, 36576, 36639, 36706, 36723, 36824, 36827, 36901, 36936, 37019, 37068, 37069, 37118, 37128, 37255, 37339, 37519, 37521, 37523, 37749, 37806, 37865, 37876, 37886, 38432);\n script_xref(name:\"VMSA\", value:\"2010-0009\");\n\n script_name(english:\"VMSA-2010-0009 : ESXi ntp and ESX Service Console third-party updates\");\n script_summary(english:\"Checks esxupdate output for the patches\");\n\n script_set_attribute(\n attribute:\"synopsis\",\n value:\n\"The remote VMware ESXi / ESX host is missing one or more\nsecurity-related patches.\"\n );\n script_set_attribute(\n attribute:\"description\",\n value:\n\"a.

Updated Service Console package python\n\n Service Console package Python update to version 2.4.3-24.el5.\n\n When the assert() system call was disabled, an input sanitization flaw was revealed in the Python string object implementation that led to a buffer overflow. The missing check for negative size values meant the Python memory allocator could allocate less memory than expected. This could result in arbitrary code execution with the Python interpreter's privileges.\n\n Multiple buffer and integer overflow flaws were found in the Python Unicode string processing and in the Python Unicode and string object implementations. An attacker could use these flaws to cause a denial of service.\n\n Multiple integer overflow flaws were found in the Python imageop module. If a Python application used the imageop module to process untrusted images, it could cause the application to disclose sensitive information, crash or, potentially, execute arbitrary code with the Python interpreter's privileges.\n\n Multiple integer underflow and overflow flaws were found in the Python snprintf() wrapper implementation. An attacker could use these flaws to cause a denial of service (memory corruption).\n\n Multiple integer overflow flaws were found in various Python modules. An attacker could use these flaws to cause a denial of service.\n\n An integer signedness error, leading to a buffer overflow, was found in the Python zlib extension module. If a Python application requested the negative byte count be flushed for a decompression stream, it could cause the application to crash or, potentially, execute arbitrary code with the Python interpreter's privileges.\n\n A flaw was discovered in the strxfrm() function of the Python locale module. Strings generated by this function were not properly NULL-terminated, which could possibly cause disclosure of data stored in the memory of a Python application using this function.\n\n The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2007-2052 CVE-2007-4965 CVE-2008-1721 CVE-2008-1887 CVE-2008-2315 CVE-2008-3142 CVE-2008-3143 CVE-2008-3144 CVE-2008-4864 CVE-2008-5031 to these issues.\n\n g. Updated Service Console package bind\n\n Service Console package bind updated to version 9.3.6-4.P1.el5\n\n The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.\n\n A flaw was found in the way BIND handles dynamic update message packets containing the 'ANY' record type. A remote attacker could use this flaw to send a specially crafted dynamic update packet that could cause named to exit with an assertion failure.\n\n The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-0696 to this issue.\n\n h. Updated Service Console package libxml2\n\n Service Console package libxml2 updated to version 2.6.26-2.1.2.8.\n\n libxml is a library for parsing and manipulating XML files. A Document Type Definition (DTD) defines the legal syntax (and also which elements can be used) for certain types of files, such as XML files.\n\n A stack overflow flaw was found in the way libxml processes the root XML document element definition in a DTD. A remote attacker could provide a specially crafted XML file, which once opened by a local, unsuspecting user, would lead to denial of service.\n\n Multiple use-after-free flaws were found in the way libxml parses the Notation and Enumeration attribute types. A remote attacker could provide a specially crafted XML file, which once opened by a local, unsuspecting user, would lead to denial of service.\n\n The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2009-2414 and CVE-2009-2416 to these issues.\n\n i. Updated Service Console package curl\n\n Service Console package curl updated to version 7.15.5-2.1.el5_3.5\n\n A cURL is affected by the previously published 'null prefix attack', caused by incorrect handling of NULL characters in X.509 certificates. If an attacker is able to get a carefully-crafted certificate signed by a trusted Certificate Authority, the attacker could use the certificate during a man-in-the-middle attack and potentially confuse cURL into accepting it by mistake.\n\n The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-2417 to this issue\n\n j. Updated Service Console package gnutls\n\n Service Console package gnutil updated to version 1.4.1-3.el5_3.5\n\n A flaw was discovered in the way GnuTLS handles NULL characters in certain fields of X.509 certificates. If an attacker is able to get a carefully-crafted certificate signed by a Certificate Authority trusted by an application using GnuTLS, the attacker could use the certificate during a man-in-the-middle attack and potentially confuse the application into accepting it by mistake.\n\n The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-2730

Updated Service Console package python\n\n Service Console package Python update to version 2.4.3-24.el5.\n\n When the assert() system call was disabled, an input sanitization\n flaw was revealed in the Python string object implementation that\n led to a buffer overflow. The missing check for negative size values\n meant the Python memory allocator could allocate less memory than\n expected. This could result in arbitrary code execution with the\n Python interpreter's privileges.\n\n Multiple buffer and integer overflow flaws were found in the Python\n Unicode string processing and in the Python Unicode and string\n object implementations. An attacker could use these flaws to cause\n a denial of service.\n\n Multiple integer overflow flaws were found in the Python imageop\n module. If a Python application used the imageop module to\n process untrusted images, it could cause the application to\n disclose sensitive information, crash or, potentially, execute\n arbitrary code with the Python interpreter's privileges.\n\n Multiple integer underflow and overflow flaws were found in the\n Python snprintf() wrapper implementation. An attacker could use\n these flaws to cause a denial of service (memory corruption).\n\n Multiple integer overflow flaws were found in various Python\n modules. An attacker could use these flaws to cause a denial of\n service.\n\n An integer signedness error, leading to a buffer overflow, was\n found in the Python zlib extension module. If a Python application\n requested the negative byte count be flushed for a decompression\n stream, it could cause the application to crash or, potentially,\n execute arbitrary code with the Python interpreter's privileges.\n\n A flaw was discovered in the strxfrm() function of the Python\n locale module. Strings generated by this function were not properly\n NULL-terminated, which could possibly cause disclosure of data\n stored in the memory of a Python application using this function.\n\n The Common Vulnerabilities and Exposures project (cve.mitre.org)\n has assigned the names CVE-2007-2052 CVE-2007-4965 CVE-2008-1721\n CVE-2008-1887 CVE-2008-2315 CVE-2008-3142 CVE-2008-3143\n CVE-2008-3144 CVE-2008-4864 CVE-2008-5031 to these issues.\n\n g. Updated Service Console package bind\n\n Service Console package bind updated to version 9.3.6-4.P1.el5\n\n The Berkeley Internet Name Domain (BIND) is an implementation of the\n Domain Name System (DNS) protocols. BIND includes a DNS server\n (named); a resolver library (routines for applications to use when\n interfacing with DNS); and tools for verifying that the DNS server\n is operating correctly.\n\n A flaw was found in the way BIND handles dynamic update message\n packets containing the 'ANY' record type. A remote attacker could\n use this flaw to send a specially crafted dynamic update packet\n that could cause named to exit with an assertion failure.\n\n The Common Vulnerabilities and Exposures project (cve.mitre.org)\n has assigned the name CVE-2009-0696 to this issue.\n\n h. Updated Service Console package libxml2\n\n Service Console package libxml2 updated to version 2.6.26-2.1.2.8.\n\n libxml is a library for parsing and manipulating XML files. A\n Document Type Definition (DTD) defines the legal syntax (and also\n which elements can be used) for certain types of files, such as XML\n files.\n\n A stack overflow flaw was found in the way libxml processes the\n root XML document element definition in a DTD. A remote attacker\n could provide a specially crafted XML file, which once opened by a\n local, unsuspecting user, would lead to denial of service.\n\n Multiple use-after-free flaws were found in the way libxml parses\n the Notation and Enumeration attribute types. A remote attacker\n could provide a specially crafted XML file, which once opened by a\n local, unsuspecting user, would lead to denial of service.\n\n The Common Vulnerabilities and Exposures project (cve.mitre.org)\n has assigned the names CVE-2009-2414 and CVE-2009-2416 to these\n issues.\n\n i. Updated Service Console package curl\n\n Service Console package curl updated to version 7.15.5-2.1.el5_3.5\n\n A cURL is affected by the previously published 'null prefix attack',\n caused by incorrect handling of NULL characters in X.509\n certificates. If an attacker is able to get a carefully-crafted\n certificate signed by a trusted Certificate Authority, the attacker\n could use the certificate during a man-in-the-middle attack and\n potentially confuse cURL into accepting it by mistake.\n\n The Common Vulnerabilities and Exposures project (cve.mitre.org)\n has assigned the name CVE-2009-2417 to this issue\n\n j. Updated Service Console package gnutls\n\n Service Console package gnutil updated to version 1.4.1-3.el5_3.5\n\n A flaw was discovered in the way GnuTLS handles NULL characters in\n certain fields of X.509 certificates. If an attacker is able to get\n a carefully-crafted certificate signed by a Certificate Authority\n trusted by an application using GnuTLS, the attacker could use the\n certificate during a man-in-the-middle attack and potentially\n confuse the application into accepting it by mistake.\n\n The Common Vulnerabilities and Exposures project (cve.mitre.org)\n has assigned the name CVE-2009-2730 to this issue\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"http://lists.vmware.com/pipermail/security-announce/2010/000087.html\"\n );\n
