Vasily Averin discovered that the NFS Lock Manager (NLM) incorrectly
handled unlock requests. A local attacker could exploit this to cause a
denial of service. (CVE-2011-2491)
Robert Swiecki discovered that mapping extensions were incorrectly handled.
A local attacker could exploit this to crash the system, leading to a
denial of service. (CVE-2011-2496)
It was discovered that the wireless stack incorrectly verified SSID
lengths. A local attacker could exploit this to cause a denial of service
or gain root privileges. (CVE-2011-2517)
Ben Pfaff discovered that Classless Queuing Disciplines (qdiscs) were being
incorrectly handled. A local attacker could exploit this to crash the
system, leading to a denial of service. (CVE-2011-2525)

This update modifies the tg3 driver to properly set the operstate value. (BZ#744699)\n\n* A KVM (Kernel-based Virtual Machine) guest can get preempted by the host, when a higher priority process needs to run. When a guest is not running for several timer interrupts in a row, ticks could be lost, resulting in the jiffies timer advancing slower than expected and timeouts taking longer than expected. To correct for the issue of lost ticks, do_timer_tsc_timekeeping() checks a reference clock source (kvm-clock when running as a KVM guest) to see if timer interrupts have been missed. If so, jiffies is incremented by the number of missed timer interrupts, ensuring that programs are woken up on time.\n(BZ#747874)\n\n* When a block device object was allocated, the bd_super field was not being explicitly initialized to NULL. Previously, users of the block device object could set bd_super to NULL when the object was released by calling the kill_block_super() function. Certain third-party file systems do not always use this function, and bd_super could therefore become uninitialized when the object was allocated again. This could cause a kernel panic in the blkdev_releasepage() function, when the uninitialized bd_super field was dereferenced.

Common Vulnerability Scoring System (CVSS)\nbase scores, which give detailed severity ratings, are available for\neach vulnerability from the CVE links in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux\noperating system.\n\nThis update fixes the following security issues :\n\n* A NULL pointer dereference flaw was found in the Linux kernel's\nStream Control Transmission Protocol (SCTP) implementation. A remote\nattacker could send a specially crafted SCTP packet to a target\nsystem, resulting in a denial of service. (CVE-2011-2482, Important)\n\n* A flaw in the Linux kernel's client-side NFS Lock Manager (NLM)\nimplementation could allow a local, unprivileged user to cause a\ndenial of service. (CVE-2011-2491, Important)\n\n* Buffer overflow flaws in the Linux kernel's netlink-based wireless\nconfiguration interface implementation could allow a local user, who\nhas the CAP_NET_ADMIN capability, to cause a denial of service or\nescalate their privileges on systems that have an active wireless\ninterface. (CVE-2011-2517, Important)\n\n* A flaw was found in the way the Linux kernel's Xen hypervisor\nimplementation emulated the SAHF instruction. When using a\nfully-virtualized guest on a host that does not use hardware assisted\npaging (HAP), such as those running CPUs that do not have support for\n(or those that have it disabled) Intel Extended Page Tables (EPT) or\nAMD Virtualization (AMD-V) Rapid Virtualization Indexing (RVI), a\nprivileged guest user could trigger this flaw to cause the hypervisor\nto crash. (CVE-2011-2519, Moderate)\n\n* An off-by-one flaw was found in the __addr_ok() macro in the Linux\nkernel's Xen hypervisor implementation when running on 64-bit systems.\nA privileged guest user could trigger this flaw to cause the\nhypervisor to crash. (CVE-2011-2901, Moderate)\n\n* /proc/[PID]/io is world-readable by default. Previously, these files\ncould be read without any further restrictions. A local, unprivileged\nuser could read these files, belonging to other, possibly privileged\nprocesses to gather confidential information, such as the length of a\npassword used in a process.

Local users may be able to cause a kernel memory leak, resulting in a denial of service.\n\n - CVE-2011-2484 Vasiliy Kulikov of Openwall discovered that the number of exit handlers that a process can register is not capped, resulting in local denial of service through resource exhaustion (CPU time and memory).\n\n - CVE-2011-2491 Vasily Averin discovered an issue with the NFS locking implementation. A malicious NFS server can cause a client to hang indefinitely in an unlock call.\n\n - CVE-2011-2492 Marek Kroemeke and Filip Palian discovered that uninitialized struct elements in the Bluetooth subsystem could lead to a leak of sensitive kernel memory through leaked stack memory.\n\n - CVE-2011-2495 Vasiliy Kulikov of Openwall discovered that the io file of a process' proc directory was world-readable, resulting in local information disclosure of information such as password lengths.\n\n - CVE-2011-2496 Robert Swiecki discovered that mremap() could be abused for local denial of service by triggering a BUG_ON assert.\n\n - CVE-2011-2497 Dan Rosenberg discovered an integer underflow in the Bluetooth subsystem, which could lead to denial of service or privilege escalation.\n\n - CVE-2011-2517 It was discovered that the netlink-based wireless configuration interface performed insufficient length validation when parsing SSIDs, resulting in buffer overflows. Local users with the CAP_NET_ADMIN capability can cause a denial of service.\n\n - CVE-2011-2525 Ben Pfaff reported an issue in the network scheduling code. A local user could cause a denial of service (NULL pointer dereference) by sending a specially crafted netlink message.\n\n - CVE-2011-2700 Mauro Carvalho Chehab of Red Hat reported a buffer overflow issue in the driver for the Si4713 FM Radio Transmitter driver used by N900 devices. Local users could exploit this issue to cause a denial of service or potentially gain elevated privileges.\n\n - CVE-2011-2723 Brent Meshier reported an issue in the GRO (generic receive offload) implementation. This can be exploited by remote users to create a denial of service (system crash) in certain network device configurations.\n\n - CVE-2011-2905 Christian Ohm discovered that the 'perf' analysis tool searches for its config files in the current working directory. This could lead to denial of service or potential privilege escalation if a user with elevated privileges is tricked into running 'perf' in a directory under the control of the attacker.\n\n - CVE-2011-2909 Vasiliy Kulikov of Openwall discovered that a programming error in the Comedi driver could lead to the information disclosure through leaked stack memory.\n\n - CVE-2011-2918 Vince Weaver discovered that incorrect handling of software event overflows in the 'perf' analysis tool could lead to local denial of service.\n\n - CVE-2011-2928 Timo Warns discovered that insufficient validation of Be filesystem images could lead to local denial of service if a malformed filesystem image is mounted.\n\n - CVE-2011-3188 Dan Kaminsky reported a weakness of the sequence number generation in the TCP protocol implementation. This can be used by remote attackers to inject packets into an active session.\n\n - CVE-2011-3191 Darren Lavender reported an issue in the Common Internet File System (CIFS).

Common Vulnerability Scoring System (CVSS)\nbase scores, which give detailed severity ratings, are available for\neach vulnerability from the CVE links in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux\noperating system.\n\nThis update fixes the following security issues :\n\n* A flaw was found in the way the Xen hypervisor implementation\nhandled instruction emulation during virtual machine exits. A\nmalicious user-space process running in an SMP guest could trick the\nemulator into reading a different instruction than the one that caused\nthe virtual machine to exit. An unprivileged guest user could trigger\nthis flaw to crash the host. This only affects systems with both an\nAMD x86 processor and the AMD Virtualization (AMD-V) extensions\nenabled. (CVE-2011-1780, Important)\n\n* A flaw allowed the tc_fill_qdisc() function in the Linux kernel's\npacket scheduler API implementation to be called on built-in qdisc\nstructures. A local, unprivileged user could use this flaw to trigger\na NULL pointer dereference, resulting in a denial of service.\n(CVE-2011-2525, Moderate)\n\n* A flaw was found in the way space was allocated in the Linux\nkernel's Global File System 2 (GFS2) implementation. If the file\nsystem was almost full, and a local, unprivileged user made an\nfallocate() request, it could result in a denial of service. Note:\nSetting quotas to prevent users from using all available disk space\nwould prevent exploitation of this flaw. (CVE-2011-2689, Moderate)\n\nThese updated kernel packages include a number of bug fixes and\nenhancements. Space precludes documenting all of these changes in this\nadvisory.

(CVE-2011-3191)\n\n - Timo Warns reported an issue in the Linux implementation for GUID partitions. Users with physical access could gain access to sensitive kernel memory by adding a storage device with a specially crafted corrupted invalid partition table. (CVE-2011-1776)\n\n - The dccp_rcv_state_process function in net/dccp/input.c in the Datagram Congestion Control Protocol (DCCP) implementation in the Linux kernel did not properly handle packets for a CLOSED endpoint, which allowed remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by sending a DCCP-Close packet followed by a DCCP-Reset packet. (CVE-2011-1093)\n\n - Integer overflow in the agp_generic_insert_memory function in drivers/char/agp/generic.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_BIND agp_ioctl ioctl call. (CVE-2011-1745)\n\n - Multiple integer overflows in the (1) agp_allocate_memory and (2) agp_create_user_memory functions in drivers/char/agp/generic.c in the Linux kernel allowed local users to trigger buffer overflows, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via vectors related to calls that specify a large number of memory pages. (CVE-2011-1746)\n\n - The agp_generic_remove_memory function in drivers/char/agp/generic.c in the Linux kernel before 2.6.38.5 did not validate a certain start parameter, which allowed local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_UNBIND agp_ioctl ioctl call, a different vulnerability than CVE-2011-1745.

(CVE-2011-0726)\n\n - The normal mmap paths all avoid creating a mapping where the pgoff inside the mapping could wrap around due to overflow. However, an expanding mremap() can take such a non-wrapping mapping and make it bigger and cause a wrapping condition.

(CVE-2011-3191)\n\n - Timo Warns reported an issue in the Linux implementation for GUID partitions. Users with physical access could gain access to sensitive kernel memory by adding a storage device with a specially crafted corrupted invalid partition table. (CVE-2011-1776)\n\n - The dccp_rcv_state_process function in net/dccp/input.c in the Datagram Congestion Control Protocol (DCCP) implementation in the Linux kernel did not properly handle packets for a CLOSED endpoint, which allowed remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by sending a DCCP-Close packet followed by a DCCP-Reset packet. (CVE-2011-1093)\n\n - Integer overflow in the agp_generic_insert_memory function in drivers/char/agp/generic.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_BIND agp_ioctl ioctl call. (CVE-2011-1745)\n\n - Multiple integer overflows in the (1) agp_allocate_memory and (2) agp_create_user_memory functions in drivers/char/agp/generic.c in the Linux kernel allowed local users to trigger buffer overflows, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via vectors related to calls that specify a large number of memory pages. (CVE-2011-1746)\n\n - The agp_generic_remove_memory function in drivers/char/agp/generic.c in the Linux kernel before 2.6.38.5 did not validate a certain start parameter, which allowed local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_UNBIND agp_ioctl ioctl call, a different vulnerability than CVE-2011-1745. (CVE-2011-2022)\n\n - The do_task_stat function in fs/proc/array.c in the Linux kernel did not perform an expected uid check, which made it easier for local users to defeat the ASLR protection mechanism by reading the start_code and end_code fields in the /proc/#####/stat file for a process executing a PIE binary. (CVE-2011-0726)\n\n - The normal mmap paths all avoid creating a mapping where the pgoff inside the mapping could wrap around due to overflow. However, an expanding mremap() can take such a non-wrapping mapping and make it bigger and cause a wrapping condition. (CVE-2011-2496)\n\n - A local unprivileged user able to access a NFS filesystem could use file locking to deadlock parts of an nfs server under some circumstance. (CVE-2011-2491)\n\n - The code for evaluating LDM partitions (in fs/partitions/ldm.c) contained bugs that could crash the kernel for certain corrupted LDM partitions.\n (CVE-2011-1017 / CVE-2011-2182)\n\n - When using a setuid root mount.cifs, local users could hijack password protected mounted CIFS shares of other local users.

(CVE-2011-1093)\n\n - The add_del_listener function in kernel/taskstats.c in\n the Linux kernel did not prevent multiple registrations\n of exit handlers, which allowed local users to cause a\n denial of service (memory and CPU consumption), and\n bypass the OOM Killer, via a crafted application.\n (CVE-2011-2484)\n\n - Integer overflow in the agp_generic_insert_memory\n function in drivers/char/agp/generic.c in the Linux\n kernel allowed local users to gain privileges or cause a\n denial of service (system crash) via a crafted\n AGPIOC_BIND agp_ioctl ioctl call. (CVE-2011-1745)\n\n - Multiple integer overflows in the (1)\n agp_allocate_memory and (2) agp_create_user_memory\n functions in drivers/char/agp/generic.c in the Linux\n kernel allowed local users to trigger buffer overflows,\n and consequently cause a denial of service (system\n crash) or possibly have unspecified other impact, via\n vectors related to calls that specify a large number of\n memory pages. (CVE-2011-1746)\n\n - The agp_generic_remove_memory function in\n drivers/char/agp/generic.c in the Linux kernel before\n 2.6.38.5 did not validate a certain start parameter,\n which allowed local users to gain privileges or cause a\n denial of service (system crash) via a crafted\n AGPIOC_UNBIND agp_ioctl ioctl call, a different\n vulnerability than CVE-2011-1745. (CVE-2011-2022)\n\n - When using a setuid root mount.cifs, local users could\n hijack password protected mounted CIFS shares of other\n local users. (CVE-2011-1585)\n\n - The do_task_stat function in fs/proc/array.c in the\n Linux kernel did not perform an expected uid check,\n which made it easier for local users to defeat the ASLR\n protection mechanism by reading the start_code and\n end_code fields in the /proc/#####/stat file for a\n process executing a PIE binary. (CVE-2011-0726)\n\n - The normal mmap paths all avoid creating a mapping where\n the pgoff inside the mapping could wrap around due to\n overflow. However, an expanding mremap() can take such a\n non-wrapping mapping and make it bigger and cause a\n wrapping condition. (CVE-2011-2496)\n\n - A local unprivileged user able to access a NFS\n filesystem could use file locking to deadlock parts of\n an nfs server under some circumstance. (CVE-2011-2491)\n\n - The code for evaluating LDM partitions (in\n fs/partitions/ldm.c) contained bugs that could crash the\n kernel for certain corrupted LDM partitions.\n (CVE-2011-1017 / CVE-2011-2182)\n\n - Multiple integer overflows in the next_pidmap function\n in kernel/pid.c in the Linux kernel allowed local users\n to cause a denial of service (system crash) via a\n crafted (1) getdents or (2) readdir system call.\n (CVE-2011-1593)\n\n - Integer overflow in the _ctl_do_mpt_command function in\n drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel\n might have allowed local users to gain privileges or\n cause a denial of service (memory corruption) via an\n ioctl call specifying a crafted value that triggers a\n heap-based buffer overflow.

of bugs\nand security issues.\n\nFollowing security issues have been fixed: CVE-2011-2495: The\n/proc/PID/io interface could be used by local attackers to gain\ninformation on other processes like number of password characters\ntyped or similar.\n\nCVE-2011-2484: The add_del_listener function in kernel/taskstats.c in\nthe Linux kernel did not prevent multiple registrations of exit\nhandlers, which allowed local users to cause a denial of service\n(memory and CPU consumption), and bypass the OOM Killer, via a crafted\napplication.\n\nCVE-2011-2022: The agp_generic_remove_memory function in\ndrivers/char/agp/generic.c in the Linux kernel before 2.6.38.5 did not\nvalidate a certain start parameter, which allowed local users to gain\nprivileges or cause a denial of service (system crash) via a crafted\nAGPIOC_UNBIND agp_ioctl ioctl call, a different vulnerability than\nCVE-2011-1745.\n\nCVE-2011-1745: Integer overflow in the agp_generic_insert_memory\nfunction in drivers/char/agp/generic.c in the Linux kernel allowed\nlocal users to gain privileges or cause a denial of service (system\ncrash) via a crafted AGPIOC_BIND agp_ioctl ioctl call.\n\nCVE-2011-2493: A denial of service on mounting invalid ext4\nfilesystems was fixed.\n\nCVE-2011-2491: A local unprivileged user able to access a NFS\nfilesystem could use file locking to deadlock parts of an nfs server\nunder some circumstance.\n\nCVE-2011-2498: Also account PTE pages when calculating OOM scoring,\nwhich could have lead to a denial of service.\n\nCVE-2011-2496: The normal mmap paths all avoid creating a mapping\nwhere the pgoff inside the mapping could wrap around due to overflow.\nHowever, an expanding mremap() can take such a non-wrapping mapping\nand make it bigger and cause a wrapping condition.\n\nCVE-2011-1017,CVE-2011-2182: The code for evaluating LDM partitions\n(in fs/partitions/ldm.c) contained bugs that could crash the kernel\nfor certain corrupted LDM partitions.\n\nCVE-2011-1479: A regression in inotify fix for a memory leak could\nlead to a double free corruption which could crash the system.\n\nCVE-2011-1927: A missing route validation issue in ip_expire() could\nbe used by remote attackers to trigger a NULL ptr dereference,\ncrashing parts of the kernel.\n\nCVE-2011-1593: Multiple integer overflows in the next_pidmap function\nin kernel/pid.c in the Linux kernel allowed local users to cause a\ndenial of service (system crash) via a crafted (1) getdents or (2)\nreaddir system call.\n\nCVE-2011-1020: The proc filesystem implementation in the Linux kernel\ndid not restrict access to the /proc directory tree of a process after\nthis process performs an exec of a setuid program, which allowed local\nusers to obtain sensitive information or cause a denial of service via\nopen, lseek, read, and write system calls.\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n

Common Vulnerability Scoring System (CVSS)\nbase scores, which give detailed severity ratings, are available for\neach vulnerability from the CVE links in the References section.\n\nSecurity issues :\n\n* Using PCI passthrough without interrupt remapping support allowed\nKVM guests to generate MSI interrupts and thus potentially inject\ntraps. A privileged guest user could use this flaw to crash the host\nor possibly escalate their privileges on the host. The fix for this\nissue can prevent PCI passthrough working and guests starting. Refer\nto Red Hat Bugzilla bug 715555 for details. (CVE-2011-1898, Important)\n\n* Flaw in the client-side NLM implementation could allow a local,\nunprivileged user to cause a denial of service. (CVE-2011-2491,\nImportant)\n\n* Integer underflow in the Bluetooth implementation could allow a\nremote attacker to cause a denial of service or escalate their\nprivileges by sending a specially crafted request to a target system\nvia Bluetooth. (CVE-2011-2497, Important)\n\n* Buffer overflows in the netlink-based wireless configuration\ninterface implementation could allow a local user, who has the\nCAP_NET_ADMIN capability, to cause a denial of service or escalate\ntheir privileges on systems that have an active wireless interface.\n(CVE-2011-2517, Important)\n\n* Flaw in the way the maximum file offset was handled for ext4 file\nsystems could allow a local, unprivileged user to cause a denial of\nservice. (CVE-2011-2695, Important)\n\n* Flaw allowed napi_reuse_skb() to be called on VLAN packets. An\nattacker on the local network could use this flaw to send crafted\npackets to a target, possibly causing a denial of service.\n(CVE-2011-1576, Moderate)\n\n* Integer signedness error in next_pidmap() could allow a local,\nunprivileged user to cause a denial of service. (CVE-2011-1593,\nModerate)\n\n* Race condition in the memory merging support (KSM) could allow a\nlocal, unprivileged user to cause a denial of service. KSM is off by\ndefault, but on systems running VDSM, or on KVM hosts, it is likely\nturned on by the ksm/ksmtuned services. (CVE-2011-2183, Moderate)\n\n* Flaw in inet_diag_bc_audit() could allow a local, unprivileged user\nto cause a denial of service. (CVE-2011-2213, Moderate)\n\n* Flaw in the way space was allocated in the Global File System 2\n(GFS2) implementation. If the file system was almost full, and a\nlocal, unprivileged user made an fallocate() request, it could result\nin a denial of service. Setting quotas to prevent users from using all\navailable disk space would prevent exploitation of this flaw.\n(CVE-2011-2689, Moderate)\n\n* Local, unprivileged users could send signals via the sigqueueinfo\nsystem call, with si_code set to SI_TKILL and with spoofed process and\nuser IDs, to other processes. This flaw does not allow existing\npermission checks to be bypassed; signals can only be sent if your\nprivileges allow you to already do so. (CVE-2011-1182, Low)\n\n* Heap overflow in the EFI GUID Partition Table (GPT) implementation\ncould allow a local attacker to cause a denial of service by mounting\na disk containing crafted partition tables. (CVE-2011-1776, Low)\n\n* Structure padding in two structures in the Bluetooth implementation\nwas not initialized properly before being copied to user-space,\npossibly allowing local, unprivileged users to leak kernel stack\nmemory to user-space. (CVE-2011-2492, Low)\n\n* /proc/[PID]/io is world-readable by default. Previously, these files\ncould be read without any further restrictions. A local, unprivileged\nuser could read these files, belonging to other, possibly privileged\nprocesses to gather confidential information, such as the length of a\npassword used in a process.

security issues have been fixed: CVE-2011-2495: The /proc/PID/io interface could be used by local attackers to gain information on other processes like number of password characters typed or similar.\n\nCVE-2011-2484: The add_del_listener function in kernel/taskstats.c in the Linux kernel did not prevent multiple registrations of exit handlers, which allowed local users to cause a denial of service (memory and CPU consumption), and bypass the OOM Killer, via a crafted application.\n\nCVE-2011-2491: A local unprivileged user able to access a NFS filesystem could use file locking to deadlock parts of an nfs server under some circumstance.\n\nCVE-2011-2496: The normal mmap paths all avoid creating a mapping where the pgoff inside the mapping could wrap around due to overflow.\nHowever, an expanding mremap() can take such a non-wrapping mapping and make it bigger and cause a wrapping condition.\n\nCVE-2011-1017,CVE-2011-2182: The code for evaluating LDM partitions (in fs/partitions/ldm.c) contained bugs that could crash the kernel for certain corrupted LDM partitions.\n\nCVE-2011-1479: A regression in inotify fix for a memory leak could lead to a double free corruption which could crash the system.\n\nCVE-2011-1593: Multiple integer overflows in the next_pidmap function in kernel/pid.c in the Linux kernel allowed local users to cause a denial of service (system crash) via a crafted (1) getdents or (2) readdir system call.\n\nCVE-2011-1020: The proc filesystem implementation in the Linux kernel did not restrict access to the /proc directory tree of a process after this process performs an exec of a setuid program, which allowed local users to obtain sensitive information or cause a denial of service via open, lseek, read, and write system calls.\n\nCVE-2011-1585: When using a setuid root mount.cifs, local users could hijack password protected mounted CIFS shares of other local users.\n\nCVE-2011-1160: Kernel information via the TPM devices could by used by local attackers to read kernel memory.\n\nCVE-2011-1577: The Linux kernel automatically evaluated partition tables of storage devices. The code for evaluating EFI GUID partitions (in fs/partitions/efi.c) contained a bug that causes a kernel oops on certain corrupted GUID partition tables, which might be used by local attackers to crash the kernel or potentially execute code.\n\nCVE-2011-1180: In the IrDA module, length fields provided by a peer for names and attributes may be longer than the destination array sizes and were not checked, this allowed local attackers (close to the irda port) to potentially corrupt memory.\n\nCVE-2011-1016: The Radeon GPU drivers in the Linux kernel did not properly validate data related to the AA resolve registers, which allowed local users to write to arbitrary memory locations associated with (1) Video RAM (aka VRAM) or (2) the Graphics Translation Table (GTT) via crafted

to 2.6.32.43 and fixes various bugs and security issues.\n\nThe following security issues were fixed :\n\n - The normal mmap paths all avoid creating a mapping where the pgoff inside the mapping could wrap around due to overflow. However, an expanding mremap() can take such a non-wrapping mapping and make it bigger and cause a wrapping condition. (CVE-2011-2496)\n\n - A local unprivileged user able to access a NFS filesystem could use file locking to deadlock parts of an nfs server under some circumstance. (CVE-2011-2491)\n\n - Fixed a race between ksmd and other memory management code, which could result in a NULL ptr dereference and kernel crash. (CVE-2011-2183)\n\n - In both trigger_scan and sched_scan operations, we were checking for the SSID length before assigning the value correctly. Since the memory was just kzalloced, the check was always failing and SSID with over 32 characters were allowed to go through. This required CAP_NET_ADMIN privileges to be exploited.\n (CVE-2011-2517)\n\n - A malicious user or buggy application could inject diagnosing byte code and trigger an infinite loop in inet_diag_bc_audit(). (CVE-2011-2213)\n\n - The code for evaluating LDM partitions (in fs/partitions/ldm.c) contained bugs that could crash the kernel for certain corrupted LDM partitions.\n (CVE-2011-1017 / CVE-2011-1012 / CVE-2011-2182)\n\n - Multiple integer overflows in the next_pidmap function in kernel/pid.c in the Linux kernel allowed local users to cause a denial of service (system crash) via a crafted (1) getdents or (2) readdir system call.\n (CVE-2011-1593)\n\n - The proc filesystem implementation in the Linux kernel did not restrict access to the /proc directory tree of a process after this process performs an exec of a setuid program, which allowed local users to obtain sensitive information or cause a denial of service via open, lseek, read, and write system calls. (CVE-2011-1020)\n\n - When using a setuid root mount.cifs, local users could hijack password protected mounted CIFS shares of other local users. (CVE-2011-1585)\n\n - Kernel information via the TPM devices could by used by local attackers to read kernel memory. (CVE-2011-1160)\n\n - The Linux kernel automatically evaluated partition tables of storage devices. The code for evaluating EFI GUID partitions (in fs/partitions/efi.c) contained a bug that causes a kernel oops on certain corrupted GUID partition tables, which might be used by local attackers to crash the kernel or potentially execute code.\n (CVE-2011-1577)\n\n - In a bluetooth ioctl, struct sco_conninfo has one padding byte in the end. Local variable cinfo of type sco_conninfo was copied to userspace with this uninizialized one byte, leading to an old stack contents leak. (CVE-2011-1078)\n\n - In a bluetooth ioctl, struct ca is copied from userspace. It was not checked whether the 'device' field was NULL terminated. This potentially leads to BUG() inside of alloc_netdev_mqs() and/or information leak by creating a device with a name made of contents of kernel stack. (CVE-2011-1079)\n\n - In ebtables rule loading, struct tmp is copied from userspace. It was not checked whether the 'name' field is NULL terminated. This may have lead to buffer overflow and passing contents of kernel stack as a module name to try_then_request_module() and, consequently, to modprobe commandline. It would be seen by all userspace processes. (CVE-2011-1080)\n\n - The econet_sendmsg function in net/econet/af_econet.c in the Linux kernel on the x86_64 platform allowed remote attackers to obtain potentially sensitive information from kernel stack memory by reading uninitialized data in the ah field of an Acorn Universal Networking (AUN) packet. (CVE-2011-1173)\n\n - net/ipv4/netfilter/arp_tables.c in the IPv4 implementation in the Linux kernel did not place the expected '0' character at the end of string data in the values of certain structure members, which allowed local users to obtain potentially sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability to issue a crafted request, and then reading the argument to the resulting modprobe process.\n (CVE-2011-1170)\n\n - net/ipv4/netfilter/ip_tables.c in the IPv4 implementation in the Linux kernel did not place the expected '0' character at the end of string data in the values of certain structure members, which allowed local users to obtain potentially sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability to issue a crafted request, and then reading the argument to the resulting modprobe process.\n (CVE-2011-1171)\n\n - net/ipv6/netfilter/ip6_tables.c in the IPv6 implementation in the Linux kernel did not place the expected '0' character at the end of string data in the values of certain structure members, which allowed local users to obtain potentially sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability to issue a crafted request, and then reading the argument to the resulting modprobe process.\n (CVE-2011-1172)\n\n - Multiple integer overflows in the (1) agp_allocate_memory and (2) agp_create_user_memory functions in drivers/char/agp/generic.c in the Linux kernel before allowed local users to trigger buffer overflows, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via vectors related to calls that specify a large number of memory pages. (CVE-2011-1746)\n\n - Integer overflow in the agp_generic_insert_memory function in drivers/char/agp/generic.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_BIND agp_ioctl ioctl call. (CVE-2011-1745)\n\n - The bcm_release function in net/can/bcm.c in the Linux kernel did not properly validate a socket data structure, which allowed local users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a crafted release operation.

kernel/signal.c in the Linux kernel before 2.6.39 allows local users to spoof the uid and pid of a signal sender via a sigqueueinfo system call. (CVE-2011-1182)\n\n - The Generic Receive Offload (GRO) implementation in the Linux kernel 2.6.18 on Red Hat Enterprise Linux 5 and 2.6.32 on Red Hat Enterprise Linux 6, as used in Red Hat Enterprise Virtualization (RHEV) Hypervisor and other products, allows remote attackers to cause a denial of service via crafted VLAN packets that are processed by the napi_reuse_skb function, leading to (1) a memory leak or (2) memory corruption, a different vulnerability than CVE-2011-1478. (CVE-2011-1576)\n\n - Multiple integer overflows in the next_pidmap function in kernel/pid.c in the Linux kernel before 2.6.38.4 allow local users to cause a denial of service (system crash) via a crafted (1) getdents or (2) readdir system call. (CVE-2011-1593)\n\n - The is_gpt_valid function in fs/partitions/efi.c in the Linux kernel before 2.6.39 does not check the size of an Extensible Firmware Interface (EFI) GUID Partition Table (GPT) entry, which allows physically proximate attackers to cause a denial of service (heap-based buffer overflow and OOPS) or obtain sensitive information from kernel heap memory by connecting a crafted GPT storage device, a different vulnerability than CVE-2011-1577. (CVE-2011-1776)\n\n - Xen 4.1 before 4.1.1 and 4.0 before 4.0.2, when using PCI passthrough on Intel VT-d chipsets that do not have interrupt remapping, allows guest OS users to gain host OS privileges by using DMA to generate MSI interrupts by writing to the interrupt injection registers. (CVE-2011-1898)\n\n - Race condition in the scan_get_next_rmap_item function in mm/ksm.c in the Linux kernel before 2.6.39.3, when Kernel SamePage Merging (KSM) is enabled, allows local users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a crafted application. (CVE-2011-2183)\n\n - The inet_diag_bc_audit function in net/ipv4/inet_diag.c in the Linux kernel before 2.6.39.3 does not properly audit INET_DIAG bytecode, which allows local users to cause a denial of service (kernel infinite loop) via crafted INET_DIAG_REQ_BYTECODE instructions in a netlink message, as demonstrated by an INET_DIAG_BC_JMP instruction with a zero yes value, a different vulnerability than CVE-2010-3880.\n (CVE-2011-2213)\n\n - The Network Lock Manager (NLM) protocol implementation in the NFS client functionality in the Linux kernel before 3.0 allows local users to cause a denial of service (system hang) via a LOCK_UN flock system call.\n (CVE-2011-2491)\n\n - The bluetooth subsystem in the Linux kernel before 3.0-rc4 does not properly initialize certain data structures, which allows local users to obtain potentially sensitive information from kernel memory via a crafted getsockopt system call, related to (1) the l2cap_sock_getsockopt_old function in net/bluetooth/l2cap_sock.c and (2) the rfcomm_sock_getsockopt_old function in net/bluetooth/rfcomm/sock.c.\n (CVE-2011-2492)\n\n - fs/proc/base.c in the Linux kernel before 2.6.39.4 does not properly restrict access to /proc/#####/io files, which allows local users to obtain sensitive I/O statistics by polling a file, as demonstrated by discovering the length of another user's password. (CVE-2011-2495)\n\n - Integer underflow in the l2cap_config_req function in net/bluetooth/l2cap_core.c in the Linux kernel before 3.0 allows remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a small command-size value within the command header of a Logical Link Control and Adaptation Protocol (L2CAP) configuration request, leading to a buffer overflow.\n (CVE-2011-2497)\n\n - Multiple buffer overflows in net/wireless/nl80211.c in the Linux kernel before 2.6.39.2 allow local users to gain privileges by leveraging the CAP_NET_ADMIN capability during scan operations with a long SSID value. (CVE-2011-2517)\n\n - The gfs2_fallocate function in fs/gfs2/file.c in the Linux kernel before 3.0-rc1 does not ensure that the size of a chunk allocation is a multiple of the block size, which allows local users to cause a denial of service (BUG and system crash) by arranging for all resource groups to have too little free space.\n (CVE-2011-2689)\n\n - Multiple off-by-one errors in the ext4 subsystem in the Linux kernel before 3.0-rc5 allow local users to cause a denial of service (BUG_ON and system crash) by accessing a sparse file in extent format with a write operation involving a block number corresponding to the largest possible 32-bit unsigned integer.\n (CVE-2011-2695)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.", "cvss3": {"exploitabilityScore": 0.9, "cvssV3": {"baseSeverity": "MEDIUM", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "PHYSICAL", "availabilityImpact": "HIGH", "integrityImpact": "NONE", "privilegesRequired": "NONE", "baseScore": 6.1, "vectorString": "CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.2}, "published": "2013-07-12T00:00:00", "type": "nessus", "title": "Oracle Linux 6 : kernel (ELSA-2011-1189)", "bulletinFamily": "scanner", "cvss2": {"severity": "HIGH", "exploitabilityScore": 6.5, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 8.3, "vectorString": "AV:A/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "ADJACENT_NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "obtainUserPrivilege": false}, "cvelist": ["CVE-2010-3880", "CVE-2011-1182", "CVE-2011-1478", "CVE-2011-1576", "CVE-2011-1577", "CVE-2011-1593", "CVE-2011-1776", "CVE-2011-1898", "CVE-2011-2183", "CVE-2011-2213", "CVE-2011-2491", "CVE-2011-2492", "CVE-2011-2495", "CVE-2011-2497", "CVE-2011-2517", "CVE-2011-2689", "CVE-2011-2695"], "modified": "2021-09-08T00:00:00", "cpe": ["cpe:/o:oracle:linux:6", "p-cpe:/a:oracle:linux:kernel", "p-cpe:/a:oracle:linux:kernel-debug", "p-cpe:/a:oracle:linux:kernel-debug-devel", "p-cpe:/a:oracle:linux:kernel-devel", "p-cpe:/a:oracle:linux:kernel-firmware", "p-cpe:/a:oracle:linux:kernel-headers", "p-cpe:/a:oracle:linux:perf"], "id": "ORACLELINUX_ELSA-2011-1189.NASL", "href": "https://www.tenable.com/plugins/nessus/68331", "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 Oracle Linux Security Advisory ELSA-2011-1189.\n##\n\ninclude('deprecated_nasl_level.inc');\ninclude('compat.inc');\n\nif (description)\n{\n script_id(68331);\n script_version(\"1.19\");\n script_set_attribute(attribute:\"plugin_modification_date\", value:\"2021/09/08\");\n\n script_cve_id(\n \"CVE-2011-1182\",\n \"CVE-2011-1576\",\n \"CVE-2011-1593\",\n \"CVE-2011-1776\",\n \"CVE-2011-1898\",\n \"CVE-2011-2183\",\n \"CVE-2011-2213\",\n \"CVE-2011-2491\",\n \"CVE-2011-2492\",\n \"CVE-2011-2495\",\n \"CVE-2011-2497\",\n \"CVE-2011-2517\",\n \"CVE-2011-2689\",\n \"CVE-2011-2695\"\n );\n script_bugtraq_id(\n 47003,\n 47497,\n 47796,\n 48333,\n 48441,\n 48472,\n 48515,\n 48538,\n 48677,\n 48697,\n 48907,\n 49141\n );\n script_xref(name:\"RHSA\", value:\"2011:1189\");\n\n script_name(english:\"Oracle Linux 6 : kernel (ELSA-2011-1189)\");\n\n script_set_attribute(attribute:\"synopsis\", value:\n\"The remote Oracle Linux host is missing one or more security updates.\");\n script_set_attribute(attribute:\"description\", value:\n\"The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the\nELSA-2011-1189 advisory.\n\n - kernel/signal.c in the Linux kernel before 2.6.39 allows local users to spoof the uid and pid of a signal\n sender via a sigqueueinfo system call.

(CVE-2011-1833, Moderate)\n\n* A denial of service flaw was found in the way the taskstats subsystem handled the registration of process exit handlers. A local, unprivileged user could register an unlimited amount of these handlers, leading to excessive CPU time and memory use.\n(CVE-2011-2484, Moderate)\n\n* A flaw was found in the way mapping expansions were handled. A local, unprivileged user could use this flaw to cause a wrapping condition, triggering a denial of service. (CVE-2011-2496, Moderate)\n\n* A flaw was found in the Linux kernel's Performance Events implementation. It could falsely lead the NMI (Non-Maskable Interrupt) Watchdog to detect a lockup and panic the system. A local, unprivileged user could use this flaw to cause a denial of service (kernel panic) using the perf tool. (CVE-2011-2521, Moderate)\n\n* A flaw in skb_gro_header_slow() in the Linux kernel could lead to GRO (Generic Receive Offload) fields being left in an inconsistent state. An attacker on the local network could use this flaw to trigger a denial of service. GRO is enabled by default in all network drivers that support it. (CVE-2011-2723, Moderate)\n\n* A flaw was found in the way the Linux kernel's Performance Events implementation handled PERF_COUNT_SW_CPU_CLOCK counter overflow. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2011-2918, Moderate)\n\n* A flaw was found in the Linux kernel's Trusted Platform Module (TPM) implementation. A local, unprivileged user could use this flaw to leak information to user-space. (CVE-2011-1160, Low)\n\n* Flaws were found in the tpacket_rcv() and packet_recvmsg() functions in the Linux kernel.

AGPGART driver implementation when handling certain IOCTL commands could allow a local user to cause a denial of service or escalate their privileges.\n (CVE-2011-1745, CVE-2011-2022, Important)\n\n - An integer overflow flaw in agp_allocate_memory() could allow a local user to cause a denial of service or escalate their privileges. (CVE-2011-1746, Important)\n\n - A race condition flaw was found in the Linux kernel's eCryptfs implementation. A local attacker could use the mount.ecryptfs_private utility to mount (and then access) a directory they would otherwise not have access to. Note: To correct this issue, a previous ecryptfs-utils update, which provides the user-space part of the fix, must also be installed. (CVE-2011-1833, Moderate)\n\n - A denial of service flaw was found in the way the taskstats subsystem handled the registration of process exit handlers. A local, unprivileged user could register an unlimited amount of these handlers, leading to excessive CPU time and memory use. (CVE-2011-2484, Moderate)\n\n - A flaw was found in the way mapping expansions were handled. A local, unprivileged user could use this flaw to cause a wrapping condition, triggering a denial of service. (CVE-2011-2496, Moderate)\n\n - A flaw was found in the Linux kernel's Performance Events implementation. It could falsely lead the NMI (Non-Maskable Interrupt) Watchdog to detect a lockup and panic the system. A local, unprivileged user could use this flaw to cause a denial of service (kernel panic) using the perf tool. (CVE-2011-2521, Moderate)\n\n - A flaw in skb_gro_header_slow() in the Linux kernel could lead to GRO (Generic Receive Offload) fields being left in an inconsistent state. An attacker on the local network could use this flaw to trigger a denial of service. GRO is enabled by default in all network drivers that support it. (CVE-2011-2723, Moderate)\n\n - A flaw was found in the way the Linux kernel's Performance Events implementation handled PERF_COUNT_SW_CPU_CLOCK counter overflow. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2011-2918, Moderate)\n\n - A flaw was found in the Linux kernel's Trusted Platform Module (TPM) implementation. A local, unprivileged user could use this flaw to leak information to user-space.\n (CVE-2011-1160, Low)\n\n - Flaws were found in the tpacket_rcv() and packet_recvmsg() functions in the Linux kernel.

A local attacker could use the\n mount.ecryptfs_private utility to mount (and then\n access) a directory they would otherwise not have access\n to. Note: To correct this issue, a previous\n ecryptfs-utils update, which provides the user-space\n part of the fix, must also be installed. (CVE-2011-1833,\n Moderate)\n\n - A denial of service flaw was found in the way the\n taskstats subsystem handled the registration of process\n exit handlers. A local, unprivileged user could register\n an unlimited amount of these handlers, leading to\n excessive CPU time and memory use. (CVE-2011-2484,\n Moderate)\n\n - A flaw was found in the way mapping expansions were\n handled. A local, unprivileged user could use this flaw\n to cause a wrapping condition, triggering a denial of\n service. (CVE-2011-2496, Moderate)\n\n - A flaw was found in the Linux kernel's Performance\n Events implementation. It could falsely lead the NMI\n (Non-Maskable Interrupt) Watchdog to detect a lockup and\n panic the system. A local, unprivileged user could use\n this flaw to cause a denial of service (kernel panic)\n using the perf tool. (CVE-2011-2521, Moderate)\n\n - A flaw in skb_gro_header_slow() in the Linux kernel\n could lead to GRO (Generic Receive Offload) fields being\n left in an inconsistent state. An attacker on the local\n network could use this flaw to trigger a denial of\n service. GRO is enabled by default in all network\n drivers that support it.

a specific socket, it's possible to corrupt (kernel) memory over network, with an ICMP packet, if the B.A.T.M.A.N. mesh protocol is used.\n\nCVE-2011-2525: A flaw allowed the tc_fill_qdisc() function in the Linux kernels packet scheduler API implementation to be called on built-in qdisc structures. A local, unprivileged user could have used this flaw to trigger a NULL pointer dereference, resulting in a denial of service.\n\nCVE-2011-2699: Fernando Gont discovered that the IPv6 stack used predictable fragment identification numbers. A remote attacker could exploit this to exhaust network resources, leading to a denial of service.\n\nCVE-2011-2213: The inet_diag_bc_audit function in net/ipv4/inet_diag.c in the Linux kernel did not properly audit INET_DIAG bytecode, which allowed local users to cause a denial of service (kernel infinite loop) via crafted INET_DIAG_REQ_BYTECODE instructions in a netlink message, as demonstrated by an INET_DIAG_BC_JMP instruction with a zero yes value, a different vulnerability than CVE-2010-3880.\n\nCVE-2011-1576: The Generic Receive Offload (GRO) implementation in the Linux kernel allowed remote attackers to cause a denial of service via crafted VLAN packets that are processed by the napi_reuse_skb function, leading to (1) a memory leak or (2) memory corruption, a different vulnerability than CVE-2011-1478.\n\nCVE-2011-2534: Buffer overflow in the clusterip_proc_write function in net/ipv4/netfilter/ipt_CLUSTERIP.c in the Linux kernel might have allowed local users to cause a denial of service or have unspecified other impact via a crafted write operation, related to string data that lacks a terminating '\\0' character.\n\nCVE-2011-1770: Integer underflow in the dccp_parse_options function (net/dccp/options.c) in the Linux kernel allowed remote attackers to cause a denial of service via a Datagram Congestion Control Protocol (DCCP) packet with an invalid feature options length, which triggered a buffer over-read.\n\nCVE-2011-2723: The skb_gro_header_slow function in include/linux/netdevice.h in the Linux kernel, when Generic Receive Offload (GRO) is enabled, reset certain fields in incorrect situations, which allowed remote attackers to cause a denial of service (system crash) via crafted network traffic.\n\nCVE-2011-2898: A kernel information leak in the AF_PACKET protocol was fixed which might have allowed local attackers to read kernel memory.\n\nCVE-2011-2203: A NULL ptr dereference on mounting corrupt hfs filesystems was fixed which
