USN-3098-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu 12.04 LTS.
Marco Grassi discovered a use-after-free condition could occur in the TCP retransmit queue handling code in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-6828)
Vladimir Benes discovered an unbounded recursion in the VLAN and TEB Generic Receive Offload (GRO) processing implementations in the Linux kernel, A remote attacker could use this to cause a stack corruption, leading to a denial of service (system crash). (CVE-2016-7039)
Pengfei Wang discovered a race condition in the audit subsystem in the Linux kernel. A local attacker could use this to corrupt audit logs or disrupt system-call auditing. (CVE-2016-6136)
Pengfei Wang discovered a race condition in the Adaptec AAC RAID controller driver in the Linux kernel when handling ioctl()s. A local attacker could use this to cause a denial of service (system crash).
(CVE-2016-6480).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

12 kernel was updated to 3.12.67 to receive various security and bugfixes. The following security bugs were fixed :\n\n - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in the Linux kernel used an incorrect buffer size for certain timeout data, which allowed local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file (bsc#1004517).\n\n - CVE-2016-7097: The filesystem implementation in the Linux kernel preserved the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions (bsc#995968).\n\n - CVE-2015-8956: The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel allowed local users to obtain sensitive information or cause a denial of service (NULL pointer dereference) via vectors involving a bind system call on a Bluetooth RFCOMM socket (bnc#1003925).\n\n - CVE-2016-5696: net/ipv4/tcp_input.c in the Linux kernel did not properly determine the rate of challenge ACK segments, which made it easier for man-in-the-middle attackers to hijack TCP sessions via a blind in-window attack (bnc#989152).\n\n - CVE-2016-6130: Race condition in the sclp_ctl_ioctl_sccb function in drivers/s390/char/sclp_ctl.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by changing a certain length value, aka a 'double fetch' vulnerability (bnc#987542).\n\n - CVE-2016-6327: drivers/infiniband/ulp/srpt/ib_srpt.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) by using an ABORT_TASK command to abort a device write operation (bnc#994748).\n\n - CVE-2016-6480: Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value, aka a 'double fetch' vulnerability (bnc#991608).\n\n - CVE-2016-6828: The tcp_check_send_head function in include/net/tcp.h in the Linux kernel did not properly maintain certain SACK state after a failed data copy, which allowed local users to cause a denial of service (tcp_xmit_retransmit_queue use-after-free and system crash) via a crafted SACK option (bnc#994296).\n\n - CVE-2016-7425: The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a certain length field, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932).\n\n - CVE-2016-8658: Stack-based buffer overflow in the brcmf_cfg80211_start_ap function in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg8021 1.c in the Linux kernel allowed local users to cause a denial of service (system crash) or possibly have unspecified other impact via a long SSID Information Element in a command to a Netlink socket (bnc#1004462).\n\n - CVE-2016-8666: The IP stack in the Linux kernel allowed remote attackers to cause a denial of service (stack consumption and panic) or possibly have unspecified other impact by triggering use of the GRO path for packets with tunnel stacking, as demonstrated by interleaved IPv4 headers and GRE headers, a related issue to CVE-2016-7039 (bsc#1001486).\n\nThe update package also includes non-security fixes.

"AV:N/AC:L/Au:N/C:N/I:N/A:C"}}, {"lastseen": "2023-03-01T14:24:09", "description": "An update for kernel is now available for Red Hat Enterprise Linux 6.\n\nRed Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands. (CVE-2016-6136, Moderate)\n\n* A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.\n(CVE-2016-9555, Moderate)\n\nBug Fix(es) :\n\n* The qlnic driver previously attempted to fetch pending transmission descriptors before all writes were complete, which lead to firmware hangs. With this update, the qlcnic driver has been fixed to complete all writes before the hardware fetches any pending transmission descriptors. As a result, the firmware no longer hangs with the qlcnic driver. (BZ#1403143)\n\n* Previously, when a NFS share was mounted, the file-system (FS) cache was incorrectly enabled even when the '-o fsc' option was not used in the mount command. Consequently, the cachefilesd service stored files in the NFS share even when not instructed to by the user. With this update, NFS does not use the FS cache if not instructed by the '-o fsc' option. As a result, NFS no longer enables caching if the '-o fsc' option is not used. (BZ# 1399172)\n\n* Previously, an NFS client and NFS server got into a NFS4 protocol loop involving a WRITE action and a NFS4ERR_EXPIRED response when the current_fileid counter got to the wraparound point by overflowing the value of 32 bits. This update fixes the NFS server to handle the current_fileid wraparound. As a result, the described NFS4 protocol loop no longer occurs. (BZ#1399174)\n\n* Previously, certain configurations of the Hewlett Packard Smart Array (HPSA) devices caused hardware to be set offline incorrectly when the HPSA driver was expected to wait for existing I/O operations to complete. Consequently, a kernel panic occurred. This update prevents the described problem. As a result, the kernel panic no longer occurs. (BZ#1399175)\n\n* Previously, memory corruption by copying data into the wrong memory locations sometimes occurred, because the __copy_tofrom_user() function was returning incorrect values. This update fixes the\n__copy_tofrom_user() function so that it no longer returns larger values than the number of bytes it was asked to copy. As a result, memory corruption no longer occurs in he described scenario.\n(BZ#1398185)\n\n* Previously, guest virtual machines (VMs) on a Hyper-V server cluster got in some cases rebooted during the graceful node failover test, because the host kept sending heartbeat packets independently of guests responding to them. This update fixes the bug by properly responding to all the heartbeat messages in the queue, even if they are pending. As a result, guest VMs no longer get rebooted under the described circumstances.

A Common Vulnerability Scoring System (CVSS) base\nscore, which gives a detailed severity rating, is available for each\nvulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux\noperating system.\n\nSecurity Fix(es) :\n\n* When creating audit records for parameters to executed children\nprocesses, an attacker can convince the Linux kernel audit subsystem\ncan create corrupt records which may allow an attacker to misrepresent\nor evade logging of executing commands. (CVE-2016-6136, Moderate)\n\n* A flaw was found in the Linux kernel's implementation of the SCTP\nprotocol. A remote attacker could trigger an out-of-bounds read with\nan offset of up to 64kB potentially causing the system to crash.\n(CVE-2016-9555, Moderate)\n\nBug Fix(es) :\n\n* The qlnic driver previously attempted to fetch pending transmission\ndescriptors before all writes were complete, which lead to firmware\nhangs. With this update, the qlcnic driver has been fixed to complete\nall writes before the hardware fetches any pending transmission\ndescriptors. As a result, the firmware no longer hangs with the qlcnic\ndriver. (BZ#1403143)\n\n* Previously, when a NFS share was mounted, the file-system (FS) cache\nwas incorrectly enabled even when the '-o fsc' option was not used in\nthe mount command. Consequently, the cachefilesd service stored files\nin the NFS share even when not instructed to by the user. With this\nupdate, NFS does not use the FS cache if not instructed by the '-o\nfsc' option. As a result, NFS no longer enables caching if the '-o\nfsc' option is not used. (BZ# 1399172)\n\n* Previously, an NFS client and NFS server got into a NFS4 protocol\nloop involving a WRITE action and a NFS4ERR_EXPIRED response when the\ncurrent_fileid counter got to the wraparound point by overflowing the\nvalue of 32 bits. This update fixes the NFS server to handle the\ncurrent_fileid wraparound. As a result, the described NFS4 protocol\nloop no longer occurs. (BZ#1399174)\n\n* Previously, certain configurations of the Hewlett Packard Smart\nArray (HPSA) devices caused hardware to be set offline incorrectly\nwhen the HPSA driver was expected to wait for existing I/O operations\nto complete. Consequently, a kernel panic occurred. This update\nprevents the described problem. As a result, the kernel panic no\nlonger occurs. (BZ#1399175)\n\n* Previously, memory corruption by copying data into the wrong memory\nlocations sometimes occurred, because the __copy_tofrom_user()\nfunction was returning incorrect values. This update fixes the\n__copy_tofrom_user() function so that it no longer returns larger\nvalues than the number of bytes it was asked to copy. As a result,\nmemory corruption no longer occurs in he described scenario.\n(BZ#1398185)\n\n* Previously, guest virtual machines (VMs) on a Hyper-V server cluster\ngot in some cases rebooted during the graceful node failover test,\nbecause the host kept sending heartbeat packets independently of\nguests responding to them. This update fixes the bug by properly\nresponding to all the heartbeat messages in the queue, even if they\nare pending. As a result, guest VMs no longer get rebooted under the\ndescribed circumstances. (BZ#1397739)\n\n* When the 'punching hole' feature of the fallocate utility was used\non an ext4 file system inode with extent depth of 1, the extent tree\nof the inode sometimes became corrupted.

update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands. (CVE-2016-6136, Moderate)\n\n* A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.\n(CVE-2016-9555, Moderate)\n\nBug Fix(es) :\n\n* The qlnic driver previously attempted to fetch pending transmission descriptors before all writes were complete, which lead to firmware hangs. With this update, the qlcnic driver has been fixed to complete all writes before the hardware fetches any pending transmission descriptors. As a result, the firmware no longer hangs with the qlcnic driver. (BZ#1403143)\n\n* Previously, when a NFS share was mounted, the file-system (FS) cache was incorrectly enabled even when the '-o fsc' option was not used in the mount command. Consequently, the cachefilesd service stored files in the NFS share even when not instructed to by the user. With this update, NFS does not use the FS cache if not instructed by the '-o fsc' option. As a result, NFS no longer enables caching if the '-o fsc' option is not used. (BZ# 1399172)\n\n* Previously, an NFS client and NFS server got into a NFS4 protocol loop involving a WRITE action and a NFS4ERR_EXPIRED response when the current_fileid counter got to the wraparound point by overflowing the value of 32 bits. This update fixes the NFS server to handle the current_fileid wraparound. As a result, the described NFS4 protocol loop no longer occurs. (BZ#1399174)\n\n* Previously, certain configurations of the Hewlett Packard Smart Array (HPSA) devices caused hardware to be set offline incorrectly when the HPSA driver was expected to wait for existing I/O operations to complete. Consequently, a kernel panic occurred. This update prevents the described problem. As a result, the kernel panic no longer occurs. (BZ#1399175)\n\n* Previously, memory corruption by copying data into the wrong memory locations sometimes occurred, because the __copy_tofrom_user() function was returning incorrect values. This update fixes the\n__copy_tofrom_user() function so that it no longer returns larger values than the number of bytes it was asked to copy. As a result, memory corruption no longer occurs in he described scenario.\n(BZ#1398185)\n\n* Previously, guest virtual machines (VMs) on a Hyper-V server cluster got in some cases rebooted during the graceful node failover test, because the host kept sending heartbeat packets independently of guests responding to them. This update fixes the bug by properly responding to all the heartbeat messages in the queue, even if they are pending. As a result, guest VMs no longer get rebooted under the described circumstances. (BZ#1397739)\n\n* When the 'punching hole' feature of the fallocate utility was used on an ext4 file system inode with extent depth of 1, the extent tree of the inode sometimes became corrupted. With this update, the underlying source code has been fixed, and extent tree corruption no longer occurs in the described situation.

With this update, the qlcnic driver has been fixed to complete\nall writes before the hardware fetches any pending transmission\ndescriptors. As a result, the firmware no longer hangs with the qlcnic\ndriver. (BZ#1403143)\n\n* Previously, when a NFS share was mounted, the file-system (FS) cache\nwas incorrectly enabled even when the '-o fsc' option was not used in\nthe mount command. Consequently, the cachefilesd service stored files\nin the NFS share even when not instructed to by the user. With this\nupdate, NFS does not use the FS cache if not instructed by the '-o\nfsc' option. As a result, NFS no longer enables caching if the '-o\nfsc' option is not used. (BZ# 1399172)\n\n* Previously, an NFS client and NFS server got into a NFS4 protocol\nloop involving a WRITE action and a NFS4ERR_EXPIRED response when the\ncurrent_fileid counter got to the wraparound point by overflowing the\nvalue of 32 bits. This update fixes the NFS server to handle the\ncurrent_fileid wraparound. As a result, the described NFS4 protocol\nloop no longer occurs. (BZ#1399174)\n\n* Previously, certain configurations of the Hewlett Packard Smart\nArray (HPSA) devices caused hardware to be set offline incorrectly\nwhen the HPSA driver was expected to wait for existing I/O operations\nto complete. Consequently, a kernel panic occurred. This update\nprevents the described problem. As a result, the kernel panic no\nlonger occurs. (BZ#1399175)\n\n* Previously, memory corruption by copying data into the wrong memory\nlocations sometimes occurred, because the __copy_tofrom_user()\nfunction was returning incorrect values. This update fixes the\n__copy_tofrom_user() function so that it no longer returns larger\nvalues than the number of bytes it was asked to copy. As a result,\nmemory corruption no longer occurs in he described scenario.\n(BZ#1398185)\n\n* Previously, guest virtual machines (VMs) on a Hyper-V server cluster\ngot in some cases rebooted during the graceful node failover test,\nbecause the host kept sending heartbeat packets independently of\nguests responding to them. This update fixes the bug by properly\nresponding to all the heartbeat messages in the queue, even if they\nare pending. As a result, guest VMs no longer get rebooted under the\ndescribed circumstances. (BZ#1397739)\n\n* When the 'punching hole' feature of the fallocate utility was used\non an ext4 file system inode with extent depth of 1, the extent tree\nof the inode sometimes became corrupted. With this update, the\nunderlying source code has been fixed, and extent tree corruption no\nlonger occurs in the described situation.

Applications using the splice() and tcp_splice_read() functionality can allow a remote attacker to force the kernel to enter a condition in which it can loop indefinitely.\n\n - It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and could subsequently perform any type of a fragmentation-based attack against legacy IPv6 nodes that do not implement RFC6946.\n\n - It was found that the blk_rq_map_user_iov() function in the Linux kernel's block device implementation did not properly restrict the type of iterator, which could allow a local attacker to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging write access to a /dev/sg device.\n\n - A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.\n\n - A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto().\n\n - It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared.

Applications using the\n splice() and tcp_splice_read() functionality can allow\n a remote attacker to force the kernel to enter a\n condition in which it can loop indefinitely.\n\n - It was discovered that a remote attacker could leverage\n the generation of IPv6 atomic fragments to trigger the\n use of fragmentation in an arbitrary IPv6 flow (in\n scenarios in which actual fragmentation of packets is\n not needed) and could subsequently perform any type of\n a fragmentation-based attack against legacy IPv6 nodes\n that do not implement RFC6946.\n\n - It was found that the blk_rq_map_user_iov() function in\n the Linux kernel's block device implementation did not\n properly restrict the type of iterator, which could\n allow a local attacker to read or write to arbitrary\n kernel memory locations or cause a denial of service\n (use-after-free) by leveraging write access to a\n /dev/sg device.\n\n - A flaw was found in the Linux kernel's implementation\n of the SCTP protocol. A remote attacker could trigger\n an out-of-bounds read with an offset of up to 64kB\n potentially causing the system to crash.\n\n - A flaw was found in the Linux networking subsystem\n where a local attacker with CAP_NET_ADMIN capabilities\n could cause an out-of-bounds memory access by creating\n a smaller-than-expected ICMP header and sending to its\n destination via sendto().\n\n - It was found that when file permissions were modified\n via chmod and the user modifying them was not in the\n owning group or capable of CAP_FSETID, the setgid bit\n would be cleared. Setting a POSIX ACL via setxattr sets\n the file permissions as well as the new ACL, but\n doesn't clear the setgid bit in a similar way. This\n could allow a local user to gain group privileges via\n certain setgid applications.\n\n - It was found that when the gcc stack protector was\n enabled, reading the /proc/keys file could cause a\n panic in the Linux kernel due to stack corruption. This\n happened because an incorrect buffer size was used to\n hold a 64-bit timeout value rendered as weeks.\n\n - A race condition flaw was found in the ioctl_send_fib()\n function in the Linux kernel's aacraid implementation.\n A local attacker could use this flaw to cause a denial\n of service (out-of-bounds access or system crash) by\n changing a certain size value.\n\n - When creating audit records for parameters to executed\n children processes, an attacker can convince the Linux\n kernel audit subsystem can create corrupt records which\n may allow an attacker to misrepresent or evade logging\n of executing commands.\n\n - A flaw was discovered in the way the Linux kernel dealt\n with paging structures.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nThese updated kernel packages include several security issues and numerous bug fixes, some of which you can see below. Space precludes documenting all of these bug fixes in this advisory. To see the complete list of bug fixes, users are directed to the related Knowledge Article: https://access.redhat.com/ articles/2857831.\n\nSecurity Fix(es) :\n\n* A use-after-free vulnerability was found in the kernel's socket recvmmsg subsystem. This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg() function.\n(CVE-2016-7117, Important)\n\n* A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and other tcp_* functions. This condition could allow an attacker to send an incorrect selective acknowledgment to existing connections, possibly resetting a connection.\n(CVE-2016-6828, Moderate)\n\n* A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.\n(CVE-2016-9555, Moderate)\n\nBug Fix(es) :\n\n* Previously, the performance of Internet Protocol over InfiniBand (IPoIB) was suboptimal due to a conflict of IPoIB with the Generic Receive Offload (GRO) infrastructure. With this update, the data cached by the IPoIB driver has been moved from a control block into the IPoIB hard header, thus avoiding the GRO problem and the corruption of IPoIB address information. As a result, the performance of IPoIB has been improved. (BZ#1390668)\n\n* Previously, when a virtual machine (VM) with PCI-Passthrough interfaces was recreated, a race condition between the eventfd daemon and the virqfd daemon occurred. Consequently, the operating system rebooted. This update fixes the race condition. As a result, the operating system no longer reboots in the described situation.\n(BZ#1391611)\n\n* Previously, a packet loss occurred when the team driver in round-robin mode was sending a large number of packets. This update fixes counting of the packets in the round-robin runner of the team driver, and the packet loss no longer occurs in the described situation. (BZ#1392023)\n\n* Previously, the virtual network devices contained in the deleted namespace could be deleted in any order. If the loopback device was not deleted as the last item, other netns devices, such as vxlan devices, could end up with dangling references to the loopback device.\nConsequently, deleting a network namespace (netns) occasionally ended by a kernel oops. With this update, the underlying source code has been fixed to ensure the correct order when deleting the virtual network devices on netns deletion. As a result, the kernel oops no longer occurs under the described circumstances. (BZ#1392024)\n\n* Previously, a Kabylake system with a Sunrise Point Platform Controller Hub (PCH) with a PCI device ID of 0xA149 showed the following warning messages during the boot :\n\n'Unknown Intel PCH (0xa149) detected.' 'Warning: Intel Kabylake processor with unknown PCH - this hardware has not undergone testing by Red Hat and might not be certified. Please consult https:/ /hardware.redhat.com for certified hardware.'\n\nThe messages were shown because this PCH was not properly recognized.\nWith this update, the problem has been fixed, and the operating system now boots without displaying the warning messages. (BZ#1392033)\n\n* Previously, the operating system occasionally became unresponsive after a long run. This was caused by a race condition between the try_to_wake_up() function and a woken up task in the core scheduler.\nWith this update, the race condition has been fixed, and the operating system no longer locks up in the described scenario.

If the loopback device was\nnot deleted as the last item, other netns devices, such as vxlan\ndevices, could end up with dangling references to the loopback device.\nConsequently, deleting a network namespace (netns) occasionally ended\nby a kernel oops. With this update, the underlying source code has\nbeen fixed to ensure the correct order when deleting the virtual\nnetwork devices on netns deletion. As a result, the kernel oops no\nlonger occurs under the described circumstances. (BZ#1392024)\n\n* Previously, a Kabylake system with a Sunrise Point Platform\nController Hub (PCH) with a PCI device ID of 0xA149 showed the\nfollowing warning messages during the boot :\n\n'Unknown Intel PCH (0xa149) detected.' 'Warning: Intel Kabylake\nprocessor with unknown PCH - this hardware has not undergone testing\nby Red Hat and might not be certified. Please consult https:/\n/hardware.redhat.com for certified hardware.'\n\nThe messages were shown because this PCH was not properly recognized.\nWith this update, the problem has been fixed, and the operating system\nnow boots without displaying the warning messages. (BZ#1392033)\n\n* Previously, the operating system occasionally became unresponsive\nafter a long run. This was caused by a race condition between the\ntry_to_wake_up() function and a woken up task in the core scheduler.\nWith this update, the race condition has been fixed, and the operating\nsystem no longer locks up in the described scenario.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* A use-after-free vulnerability was found in the kernels socket recvmmsg subsystem. This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg() function.\n(CVE-2016-7117, Important)\n\n* An out-of-bounds heap memory access leading to a Denial of Service, heap disclosure, or further impact was found in setsockopt(). The function call is normally restricted to root, however some processes with cap_sys_admin may also be able to trigger this flaw in privileged container environments. (CVE-2016-4998, Moderate)\n\n* A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and other tcp_* functions. This condition could allow an attacker to send an incorrect selective acknowledgment to existing connections, possibly resetting a connection.\n(CVE-2016-6828, Moderate)\n\nBug Fix(es) :\n\n* When parallel NFS returned a file layout, a kernel crash sometimes occurred. This update removes the call to the BUG_ON() function from a code path of a client that returns the file layout. As a result, the kernel no longer crashes in the described situation. (BZ#1385480)\n\n* When a guest virtual machine (VM) on Microsoft Hyper-V was set to crash on a Nonmaskable Interrupt (NMI) that was injected from the host, this VM became unresponsive and did not create the vmcore dump file. This update applies a set of patches to the Virtual Machine Bus kernel driver (hv_vmbus) that fix this bug. As a result, the VM now first creates and saves the vmcore dump file and then reboots.\n(BZ#1385482)\n\n* From Red Hat Enterprise Linux 6.6 to 6.8, the IPv6 routing cache occasionally showed incorrect values. This update fixes the DST_NOCOUNT mechanism, and the IPv6 routing cache now shows correct values. (BZ# 1391974)\n\n* When using the ixgbe driver and the software Fibre Channel over Ethernet (FCoE) stack, suboptimal performance in some cases occurred on systems with a large number of CPUs. This update fixes the fc_exch_alloc() function to try all the available exchange managers in the list for an available exchange ID. This change avoids failing allocations, which previously led to the host busy status.\n(BZ#1392818)\n\n* When the vmwgfx kernel module loads, it overrides the boot resolution automatically. Consequently, users were not able to change the resolution by manual setting of the kernel's 'vga=' parameter in the /boot/grub/ grub.conf file. This update adds the 'nomodeset' parameter, which can be set in the /boot/grub/grub.conf file. The 'nomodeset' parameter allows the users to prevent the vmwgfx driver from loading. As a result, the setting of the 'vga=' parameter works as expected, in case that vmwgfx does not load. (BZ#1392875)\n\n* When Red Hat Enterprise Linux 6.8 was booted on SMBIOS 3.0 based systems, Desktop Management Interface (DMI) information, which is referenced by several applications, such as NEC server's memory RAS utility, was missing entries in the sysfs virtual file system. This update fixes the underlying source code, and sysfs now shows the DMI information as expected. (BZ# 1393464)\n\n* Previously, bonding mode active backup and the propagation of the media access control (MAC) address to a VLAN interface did not work in Red Hat Enterprise Linux 6.8, when the fail_over_mac bonding parameter was set to fail_over_mac=active. With this update, the underlying source code has been fixed so that the VLANs continue inheriting the MAC address of the active physical interface until the VLAN MAC address is explicitly set to any value. As a result, IPv6 EUI64 addresses for the VLAN can reflect any changes to the MAC address of the physical interface, and Duplicate Address Detection (DAD) behaves as expected.

"AV:N/AC:L/Au:N/C:C/I:C/A:C"}}, {"lastseen": "2023-02-05T14:20:58", "description": "An update for kernel is now available for Red Hat Enterprise Linux 6.\n\nRed Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* A use-after-free vulnerability was found in the kernels socket recvmmsg subsystem. This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg() function.\n(CVE-2016-7117, Important)\n\n* An out-of-bounds heap memory access leading to a Denial of Service, heap disclosure, or further impact was found in setsockopt(). The function call is normally restricted to root, however some processes with cap_sys_admin may also be able to trigger this flaw in privileged container environments. (CVE-2016-4998, Moderate)\n\n* A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and other tcp_* functions. This condition could allow an attacker to send an incorrect selective acknowledgment to existing connections, possibly resetting a connection.\n(CVE-2016-6828, Moderate)\n\nBug Fix(es) :\n\n* When parallel NFS returned a file layout, a kernel crash sometimes occurred. This update removes the call to the BUG_ON() function from a code path of a client that returns the file layout. As a result, the kernel no longer crashes in the described situation. (BZ#1385480)\n\n* When a guest virtual machine (VM) on Microsoft Hyper-V was set to crash on a Nonmaskable Interrupt (NMI) that was injected from the host, this VM became unresponsive and did not create the vmcore dump file. This update applies a set of patches to the Virtual Machine Bus kernel driver (hv_vmbus) that fix this bug. As a result, the VM now first creates and saves the vmcore dump file and then reboots.\n(BZ#1385482)\n\n* From Red Hat Enterprise Linux 6.6 to 6.8, the IPv6 routing cache occasionally showed incorrect values. This update fixes the DST_NOCOUNT mechanism, and the IPv6 routing cache now shows correct values. (BZ# 1391974)\n\n* When using the ixgbe driver and the software Fibre Channel over Ethernet (FCoE) stack, suboptimal performance in some cases occurred on systems with a large number of CPUs. This update fixes the fc_exch_alloc() function to try all the available exchange managers in the list for an available exchange ID. This change avoids failing allocations, which previously led to the host busy status.\n(BZ#1392818)\n\n* When the vmwgfx kernel module loads, it overrides the boot resolution automatically. Consequently, users were not able to change the resolution by manual setting of the kernel's 'vga=' parameter in the /boot/grub/ grub.conf file. This update adds the 'nomodeset' parameter, which can be set in the /boot/grub/grub.conf file. The 'nomodeset' parameter allows the users to prevent the vmwgfx driver from loading. As a result, the setting of the 'vga=' parameter works as expected, in case that vmwgfx does not load. (BZ#1392875)\n\n* When Red Hat Enterprise Linux 6.8 was booted on SMBIOS 3.0 based systems, Desktop Management Interface (DMI) information, which is referenced by several applications, such as NEC server's memory RAS utility, was missing entries in the sysfs virtual file system. This update fixes the underlying source code, and sysfs now shows the DMI information as expected. (BZ# 1393464)\n\n* Previously, bonding mode active backup and the propagation of the media access control (MAC) address to a VLAN interface did not work in Red Hat Enterprise Linux 6.8, when the fail_over_mac bonding parameter was set to fail_over_mac=active. With this update, the underlying source code has been fixed so that the VLANs continue inheriting the MAC address of the active physical interface until the VLAN MAC address is explicitly set to any value. As a result, IPv6 EUI64 addresses for the VLAN can reflect any changes to the MAC address of the physical interface, and Duplicate Address Detection (DAD) behaves as expected.

A Common Vulnerability Scoring System (CVSS) base\nscore, which gives a detailed severity rating, is available for each\nvulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux\noperating system.\n\nSecurity Fix(es) :\n\n* A use-after-free vulnerability was found in the kernels socket\nrecvmmsg subsystem. This may allow remote attackers to corrupt memory\nand may allow execution of arbitrary code. This corruption takes place\nduring the error handling routines within __sys_recvmmsg() function.\n(CVE-2016-7117, Important)\n\n* An out-of-bounds heap memory access leading to a Denial of Service,\nheap disclosure, or further impact was found in setsockopt(). The\nfunction call is normally restricted to root, however some processes\nwith cap_sys_admin may also be able to trigger this flaw in privileged\ncontainer environments. (CVE-2016-4998, Moderate)\n\n* A use-after-free vulnerability was found in\ntcp_xmit_retransmit_queue and other tcp_* functions. This condition\ncould allow an attacker to send an incorrect selective acknowledgment\nto existing connections, possibly resetting a connection.\n(CVE-2016-6828, Moderate)\n\nBug Fix(es) :\n\n* When parallel NFS returned a file layout, a kernel crash sometimes\noccurred. This update removes the call to the BUG_ON() function from a\ncode path of a client that returns the file layout. As a result, the\nkernel no longer crashes in the described situation. (BZ#1385480)\n\n* When a guest virtual machine (VM) on Microsoft Hyper-V was set to\ncrash on a Nonmaskable Interrupt (NMI) that was injected from the\nhost, this VM became unresponsive and did not create the vmcore dump\nfile. This update applies a set of patches to the Virtual Machine Bus\nkernel driver (hv_vmbus) that fix this bug. As a result, the VM now\nfirst creates and saves the vmcore dump file and then reboots.\n(BZ#1385482)\n\n* From Red Hat Enterprise Linux 6.6 to 6.8, the IPv6 routing cache\noccasionally showed incorrect values. This update fixes the\nDST_NOCOUNT mechanism, and the IPv6 routing cache now shows correct\nvalues. (BZ# 1391974)\n\n* When using the ixgbe driver and the software Fibre Channel over\nEthernet (FCoE) stack, suboptimal performance in some cases occurred\non systems with a large number of CPUs. This update fixes the\nfc_exch_alloc() function to try all the available exchange managers in\nthe list for an available exchange ID. This change avoids failing\nallocations, which previously led to the host busy status.\n(BZ#1392818)\n\n* When the vmwgfx kernel module loads, it overrides the boot\nresolution automatically. Consequently, users were not able to change\nthe resolution by manual setting of the kernel's 'vga=' parameter in\nthe /boot/grub/ grub.conf file. This update adds the 'nomodeset'\nparameter, which can be set in the /boot/grub/grub.conf file. The\n'nomodeset' parameter allows the users to prevent the vmwgfx driver\nfrom loading. As a result, the setting of the 'vga=' parameter works\nas expected, in case that vmwgfx does not load. (BZ#1392875)\n\n* When Red Hat Enterprise Linux 6.8 was booted on SMBIOS 3.0 based\nsystems, Desktop Management Interface (DMI) information, which is\nreferenced by several applications, such as NEC server's memory RAS\nutility, was missing entries in the sysfs virtual file system. This\nupdate fixes the underlying source code, and sysfs now shows the DMI\ninformation as expected. (BZ# 1393464)\n\n* Previously, bonding mode active backup and the propagation of the\nmedia access control (MAC) address to a VLAN interface did not work in\nRed Hat Enterprise Linux 6.8, when the fail_over_mac bonding parameter\nwas set to fail_over_mac=active. With this update, the underlying\nsource code has been fixed so that the VLANs continue inheriting the\nMAC address of the active physical interface until the VLAN MAC\naddress is explicitly set to any value. As a result, IPv6 EUI64\naddresses for the VLAN can reflect any changes to the MAC address of\nthe physical interface, and Duplicate Address Detection (DAD) behaves\nas expected.

Consequently, users were not able to change the resolution by manual setting of the kernel's 'vga=' parameter in the /boot/grub/grub.conf file. This update adds the 'nomodeset' parameter, which can be set in the /boot/grub/grub.conf file. The 'nomodeset' parameter allows the users to prevent the vmwgfx driver from loading. As a result, the setting of the 'vga=' parameter works as expected, in case that vmwgfx does not load.\n\n - When Scientific Linux 6.8 was booted on SMBIOS 3.0 based systems, Desktop Management Interface (DMI) information, which is referenced by several applications, such as NEC server's memory RAS utility, was missing entries in the sysfs virtual file system. This update fixes the underlying source code, and sysfs now shows the DMI information as expected.\n\n - Previously, bonding mode active backup and the propagation of the media access control (MAC) address to a VLAN interface did not work in Scientific Linux 6.8, when the fail_over_mac bonding parameter was set to fail_over_mac=active. With this update, the underlying source code has been fixed so that the VLANs continue inheriting the MAC address of the active physical interface until the VLAN MAC address is explicitly set to any value. As a result, IPv6 EUI64 addresses for the VLAN can reflect any changes to the MAC address of the physical interface, and Duplicate Address Detection (DAD) behaves as expected.", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 9.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2017-01-13T00:00:00", "type": "nessus", "title": "Scientific Linux Security Update : kernel on SL6.x i386/x86_64 (20170110)", "bulletinFamily": "scanner", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "obtainUserPrivilege": false}, "cvelist": ["CVE-2016-4998", "CVE-2016-6828", "CVE-2016-7117"], "modified": "2021-01-14T00:00:00", "cpe": ["p-cpe:/a:fermilab:scientific_linux:kernel", "p-cpe:/a:fermilab:scientific_linux:kernel-abi-whitelists", "p-cpe:/a:fermilab:scientific_linux:kernel-debug", "p-cpe:/a:fermilab:scientific_linux:kernel-debug-debuginfo", "p-cpe:/a:fermilab:scientific_linux:kernel-debug-devel", "p-cpe:/a:fermilab:scientific_linux:kernel-debuginfo", "p-cpe:/a:fermilab:scientific_linux:kernel-debuginfo-common-i686", "p-cpe:/a:fermilab:scientific_linux:kernel-debuginfo-common-x86_64", "p-cpe:/a:fermilab:scientific_linux:kernel-devel", "p-cpe:/a:fermilab:scientific_linux:kernel-doc", "p-cpe:/a:fermilab:scientific_linux:kernel-firmware", "p-cpe:/a:fermilab:scientific_linux:kernel-headers", "p-cpe:/a:fermilab:scientific_linux:perf", "p-cpe:/a:fermilab:scientific_linux:perf-debuginfo", "p-cpe:/a:fermilab:scientific_linux:python-perf", "p-cpe:/a:fermilab:scientific_linux:python-perf-debuginfo", "x-cpe:/o:fermilab:scientific_linux"], "id": "SL_20170110_KERNEL_ON_SL6_X.NASL", "href": "https://www.tenable.com/plugins/nessus/96481", "sourceData": "#%NASL_MIN_LEVEL 70300\n#\n# (C) Tenable Network Security, Inc.\n#\n# The descriptive text is (C) Scientific Linux.\n#\n\ninclude('deprecated_nasl_level.inc');\ninclude('compat.inc');\n\nif (description)\n{\n script_id(96481);\n script_version(\"3.7\");\n script_set_attribute(attribute:\"plugin_modification_date\", value:\"2021/01/14\");\n\n script_cve_id(\"CVE-2016-4998\", \"CVE-2016-6828\", \"CVE-2016-7117\");\n\n script_name(english:\"Scientific Linux Security Update : kernel on SL6.x i386/x86_64 (20170110)\");\n script_summary(english:\"Checks rpm output for the updated packages\");\n\n script_set_attribute(\n attribute:\"synopsis\", \n value:\n\"The remote Scientific Linux host is missing one or more security\nupdates.\"\n );\n script_set_attribute(\n attribute:\"description\", \n value:\n\"Security Fix(es) :\n\n - A use-after-free vulnerability was found in the kernels\n socket recvmmsg subsystem. This may allow remote\n attackers to corrupt memory and may allow execution of\n arbitrary code. This corruption takes place during the\n error handling routines within __sys_recvmmsg()\n function. (CVE-2016-7117, Important)\n\n - An out-of-bounds heap memory access leading to a Denial\n of Service, heap disclosure, or further impact was found\n in setsockopt(). The function call is normally\n restricted to root, however some processes with\n cap_sys_admin may also be able to trigger this flaw in\n privileged container environments. (CVE-2016-4998,\n Moderate)\n\n - A use-after-free vulnerability was found in\n tcp_xmit_retransmit_queue and other tcp_* functions.\n This condition could allow an attacker to send an\n incorrect selective acknowledgment to existing\n connections, possibly resetting a connection.\n (CVE-2016-6828, Moderate)\n\nBug Fix(es) :\n\n - When parallel NFS returned a file layout, a kernel crash\n sometimes occurred. This update removes the call to the\n BUG_ON() function from a code path of a client that\n returns the file layout. As a result, the kernel no\n longer crashes in the described situation.\n\n - When a guest virtual machine (VM) on Microsoft Hyper-V\n was set to crash on a Nonmaskable Interrupt (NMI) that\n was injected from the host, this VM became unresponsive\n and did not create the vmcore dump file. This update\n applies a set of patches to the Virtual Machine Bus\n kernel driver (hv_vmbus) that fix this bug. As a result,\n the VM now first creates and saves the vmcore dump file\n and then reboots.\n\n - From Scientific Linux 6.6 to 6.8, the IPv6 routing cache\n occasionally showed incorrect values. This update fixes\n the DST_NOCOUNT mechanism, and the IPv6 routing cache\n now shows correct values.\n\n - When using the ixgbe driver and the software Fibre\n Channel over Ethernet (FCoE) stack, suboptimal\n performance in some cases occurred on systems with a\n large number of CPUs. This update fixes the\n fc_exch_alloc() function to try all the available\n exchange managers in the list for an available exchange\n ID. This change avoids failing allocations, which\n previously led to the host busy status.\n\n - When the vmwgfx kernel module loads, it overrides the\n boot resolution automatically. Consequently, users were\n not able to change the resolution by manual setting of\n the kernel's 'vga=' parameter in the\n /boot/grub/grub.conf file. This update adds the\n 'nomodeset' parameter, which can be set in the\n /boot/grub/grub.conf file. The 'nomodeset' parameter\n allows the users to prevent the vmwgfx driver from\n loading. As a result, the setting of the 'vga='\n parameter works as expected, in case that vmwgfx does\n not load.\n\n - When Scientific Linux 6.8 was booted on SMBIOS 3.0 based\n systems, Desktop Management Interface (DMI) information,\n which is referenced by several applications, such as NEC\n server's memory RAS utility, was missing entries in the\n sysfs virtual file system.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nThese updated kernel packages include several security issues and numerous bug fixes, some of which you can see below. Space precludes documenting all of these bug fixes in this advisory. To see the complete list of bug fixes, users are directed to the related Knowledge Article: https://access.redhat.com/ articles/2857831.\n\nSecurity Fix(es) :\n\n* A use-after-free vulnerability was found in the kernel's socket recvmmsg subsystem. This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg() function.\n(CVE-2016-7117, Important)\n\n* A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and other tcp_* functions. This condition could allow an attacker to send an incorrect selective acknowledgment to existing connections, possibly resetting a connection.\n(CVE-2016-6828, Moderate)\n\n* A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.\n(CVE-2016-9555, Moderate)\n\nBug Fix(es) :\n\n* Previously, the performance of Internet Protocol over InfiniBand (IPoIB) was suboptimal due to a conflict of IPoIB with the Generic Receive Offload (GRO) infrastructure. With this update, the data cached by the IPoIB driver has been moved from a control block into the IPoIB hard header, thus avoiding the GRO problem and the corruption of IPoIB address information. As a result, the performance of IPoIB has been improved. (BZ#1390668)\n\n* Previously, when a virtual machine (VM) with PCI-Passthrough interfaces was recreated, a race condition between the eventfd daemon and the virqfd daemon occurred. Consequently, the operating system rebooted. This update fixes the race condition. As a result, the operating system no longer reboots in the described situation.\n(BZ#1391611)\n\n* Previously, a packet loss occurred when the team driver in round-robin mode was sending a large number of packets. This update fixes counting of the packets in the round-robin runner of the team driver, and the packet loss no longer occurs in the described situation. (BZ#1392023)\n\n* Previously, the virtual network devices contained in the deleted namespace could be deleted in any order. If the loopback device was not deleted as the last item, other netns devices, such as vxlan devices, could end up with dangling references to the loopback device.\nConsequently, deleting a network namespace (netns) occasionally ended by a kernel oops. With this update, the underlying source code has been fixed to ensure the correct order when deleting the virtual network devices on netns deletion. As a result, the kernel oops no longer occurs under the described circumstances. (BZ#1392024)\n\n* Previously, a Kabylake system with a Sunrise Point Platform Controller Hub (PCH) with a PCI device ID of 0xA149 showed the following warning messages during the boot :\n\n'Unknown Intel PCH (0xa149) detected.' 'Warning: Intel Kabylake processor with unknown PCH - this hardware has not undergone testing by Red Hat and might not be certified. Please consult https:/ /hardware.redhat.com for certified hardware.'\n\nThe messages were shown because this PCH was not properly recognized.\nWith this update, the problem has been fixed, and the operating system now boots without displaying the warning messages. (BZ#1392033)\n\n* Previously, the operating system occasionally became unresponsive after a long run. This was caused by a race condition between the try_to_wake_up() function and a woken up task in the core scheduler.\nWith this update, the race condition has been fixed, and the operating system no longer locks up in the described scenario.

available for Red Hat Enterprise Linux 6.\n\nRed Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* A use-after-free vulnerability was found in the kernels socket recvmmsg subsystem. This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg() function.\n(CVE-2016-7117, Important)\n\n* An out-of-bounds heap memory access leading to a Denial of Service, heap disclosure, or further impact was found in setsockopt(). The function call is normally restricted to root, however some processes with cap_sys_admin may also be able to trigger this flaw in privileged container environments. (CVE-2016-4998, Moderate)\n\n* A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and other tcp_* functions. This condition could allow an attacker to send an incorrect selective acknowledgment to existing connections, possibly resetting a connection.\n(CVE-2016-6828, Moderate)\n\nBug Fix(es) :\n\n* When parallel NFS returned a file layout, a kernel crash sometimes occurred. This update removes the call to the BUG_ON() function from a code path of a client that returns the file layout. As a result, the kernel no longer crashes in the described situation. (BZ#1385480)\n\n* When a guest virtual machine (VM) on Microsoft Hyper-V was set to crash on a Nonmaskable Interrupt (NMI) that was injected from the host, this VM became unresponsive and did not create the vmcore dump file. This update applies a set of patches to the Virtual Machine Bus kernel driver (hv_vmbus) that fix this bug. As a result, the VM now first creates and saves the vmcore dump file and then reboots.\n(BZ#1385482)\n\n* From Red Hat Enterprise Linux 6.6 to 6.8, the IPv6 routing cache occasionally showed incorrect values. This update fixes the DST_NOCOUNT mechanism, and the IPv6 routing cache now shows correct values. (BZ# 1391974)\n\n* When using the ixgbe driver and the software Fibre Channel over Ethernet (FCoE) stack, suboptimal performance in some cases occurred on systems with a large number of CPUs. This update fixes the fc_exch_alloc() function to try all the available exchange managers in the list for an available exchange ID. This change avoids failing allocations, which previously led to the host busy status.\n(BZ#1392818)\n\n* When the vmwgfx kernel module loads, it overrides the boot resolution automatically. Consequently, users were not able to change the resolution by manual setting of the kernel's 'vga=' parameter in the /boot/grub/ grub.conf file. This update adds the 'nomodeset' parameter, which can be set in the /boot/grub/grub.conf file. The 'nomodeset' parameter allows the users to prevent the vmwgfx driver from loading. As a result, the setting of the 'vga=' parameter works as expected, in case that vmwgfx does not load. (BZ#1392875)\n\n* When Red Hat Enterprise Linux 6.8 was booted on SMBIOS 3.0 based systems, Desktop Management Interface (DMI) information, which is referenced by several applications, such as NEC server's memory RAS utility, was missing entries in the sysfs virtual file system. This update fixes the underlying source code, and sysfs now shows the DMI information as expected. (BZ# 1393464)\n\n* Previously, bonding mode active backup and the propagation of the media access control (MAC) address to a VLAN interface did not work in Red Hat Enterprise Linux 6.8, when the fail_over_mac bonding parameter was set to fail_over_mac=active. With this update, the underlying source code has been fixed so that the VLANs continue inheriting the MAC address of the active physical interface until the VLAN MAC address is explicitly set to any value. As a result, IPv6 EUI64 addresses for the VLAN can reflect any changes to the MAC address of the physical interface, and Duplicate Address Detection (DAD) behaves as expected.

A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.\n(CVE-2016-9555, Moderate)\n\nBug Fix(es) :\n\n* Previously, the performance of Internet Protocol over InfiniBand (IPoIB) was suboptimal due to a conflict of IPoIB with the Generic Receive Offload (GRO) infrastructure. With this update, the data cached by the IPoIB driver has been moved from a control block into the IPoIB hard header, thus avoiding the GRO problem and the corruption of IPoIB address information. As a result, the performance of IPoIB has been improved. (BZ#1390668)\n\n* Previously, when a virtual machine (VM) with PCI-Passthrough interfaces was recreated, a race condition between the eventfd daemon and the virqfd daemon occurred. Consequently, the operating system rebooted. This update fixes the race condition. As a result, the operating system no longer reboots in the described situation.\n(BZ#1391611)\n\n* Previously, a packet loss occurred when the team driver in round-robin mode was sending a large number of packets. This update fixes counting of the packets in the round-robin runner of the team driver, and the packet loss no longer occurs in the described situation. (BZ#1392023)\n\n* Previously, the virtual network devices contained in the deleted namespace could be deleted in any order. If the loopback device was not deleted as the last item, other netns devices, such as vxlan devices, could end up with dangling references to the loopback device.\nConsequently, deleting a network namespace (netns) occasionally ended by a kernel oops. With this update, the underlying source code has been fixed to ensure the correct order when deleting the virtual network devices on netns deletion. As a result, the kernel oops no longer occurs under the described circumstances. (BZ#1392024)\n\n* Previously, a Kabylake system with a Sunrise Point Platform Controller Hub (PCH) with a PCI device ID of 0xA149 showed the following warning messages during the boot :\n\n'Unknown Intel PCH (0xa149) detected.' 'Warning: Intel Kabylake processor with unknown PCH - this hardware has not undergone testing by Red Hat and might not be certified. Please consult https:/ /hardware.redhat.com for certified hardware.'\n\nThe messages were shown because this PCH was not properly recognized.\nWith this update, the problem has been fixed, and the operating system now boots without displaying the warning messages. (BZ#1392033)\n\n* Previously, the operating system occasionally became unresponsive after a long run. This was caused by a race condition between the try_to_wake_up() function and a woken up task in the core scheduler.\nWith this update, the race condition has been fixed, and the operating system no longer locks up in the described scenario.

With this update, the data\ncached by the IPoIB driver has been moved from a control block into\nthe IPoIB hard header, thus avoiding the GRO problem and the\ncorruption of IPoIB address information. As a result, the performance\nof IPoIB has been improved. (BZ#1390668)\n\n* Previously, when a virtual machine (VM) with PCI-Passthrough\ninterfaces was recreated, a race condition between the eventfd daemon\nand the virqfd daemon occurred. Consequently, the operating system\nrebooted. This update fixes the race condition. As a result, the\noperating system no longer reboots in the described situation.\n(BZ#1391611)\n\n* Previously, a packet loss occurred when the team driver in\nround-robin mode was sending a large number of packets. This update\nfixes counting of the packets in the round-robin runner of the team\ndriver, and the packet loss no longer occurs in the described\nsituation. (BZ#1392023)\n\n* Previously, the virtual network devices contained in the deleted\nnamespace could be deleted in any order. If the loopback device was\nnot deleted as the last item, other netns devices, such as vxlan\ndevices, could end up with dangling references to the loopback device.\nConsequently, deleting a network namespace (netns) occasionally ended\nby a kernel oops. With this update, the underlying source code has\nbeen fixed to ensure the correct order when deleting the virtual\nnetwork devices on netns deletion. As a result, the kernel oops no\nlonger occurs under the described circumstances. (BZ#1392024)\n\n* Previously, a Kabylake system with a Sunrise Point Platform\nController Hub (PCH) with a PCI device ID of 0xA149 showed the\nfollowing warning messages during the boot :\n\n'Unknown Intel PCH (0xa149) detected.' 'Warning: Intel Kabylake\nprocessor with unknown PCH - this hardware has not undergone testing\nby Red Hat and might not be certified. Please consult https:/\n/hardware.redhat.com for certified hardware.'\n\nThe messages were shown because this PCH was not properly recognized.\nWith this update, the problem has been fixed, and the operating system\nnow boots without displaying the warning messages. (BZ#1392033)\n\n* Previously, the operating system occasionally became unresponsive\nafter a long run. This was caused by a race condition between the\ntry_to_wake_up() function and a woken up task in the core scheduler.\nWith this update, the race condition has been fixed, and the operating\nsystem no longer locks up in the described scenario. (BZ#1393719)\n\nNote that Tenable Network Security has attempted to extract the\npreceding description block directly from the corresponding Red Hat\nsecurity advisory.

There is an information leak in file 'sound/core/timer.c' of the latest mainline Linux kernel, the stack object aEURoetreadaEUR has a total size of 32 bytes. It contains a 8-bytes padding, which is not initialized but sent to user via copy_to_user(), resulting a kernel leak.(CVE-2016-4569)\n\n - A vulnerability was found in Linux kernel. There is an information leak in file sound/core/timer.c of the latest mainline Linux kernel. The stack object aEURoer1aEUR has a total size of 32 bytes. Its field aEURoeeventaEUR and aEURoevalaEUR both contain 4 bytes padding. These 8 bytes padding bytes are sent to user without being initialized.(CVE-2016-4578)\n\n - The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does not properly initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request.(CVE-2016-4580)\n\n - fs/pnode.c in the Linux kernel before 4.5.4 does not properly traverse a mount propagation tree in a certain case involving a slave mount, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted series of mount system calls.(CVE-2016-4581)\n\n - Use after free vulnerability was found in percpu using previously allocated memory in bpf. First\n __alloc_percpu_gfp() is called, then the memory is freed with free_percpu() which triggers async pcpu_balance_work and then pcpu_extend_area_map could use a chunk after it has been freed.(CVE-2016-4794)\n\n - Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel before 4.5.2 allows local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions.(CVE-2016-4805)\n\n - A vulnerability was found in the Linux kernel. Payloads of NM entries are not supposed to contain NUL. When such entry is processed, only the part prior to the first NUL goes into the concatenation (i.e. the directory entry name being encoded by a bunch of NM entries). The process stops when the amount collected so far + the claimed amount in the current NM entry exceed 254. However, the value returned as the total length is the sum of *claimed* sizes, not the actual amount collected. And that's what will be passed to readdir() callback as the name length - 8Kb\n __copy_to_user() from a buffer allocated by\n __get_free_page().(CVE-2016-4913)\n\n - A flaw was discovered in processing setsockopt for 32 bit processes on 64 bit systems. This flaw will allow attackers to alter arbitrary kernel memory when unloading a kernel module. This action is usually restricted to root-privileged users but can also be leveraged if the kernel is compiled with CONFIG_USER_NS and CONFIG_NET_NS and the user is granted elevated privileges.(CVE-2016-4997)\n\n - An out-of-bounds heap memory access leading to a Denial of Service, heap disclosure, or further impact was found in setsockopt(). The function call is normally restricted to root, however some processes with cap_sys_admin may also be able to trigger this flaw in privileged container environments.(CVE-2016-4998)\n\n - A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.(CVE-2016-5195)\n\n - It was found that the RFC 5961 challenge ACK rate limiting as implemented in the Linux kernel's networking subsystem allowed an off-path attacker to leak certain information about a given connection by creating congestion on the global challenge ACK rate limit counter and then measuring the changes by probing packets. An off-path attacker could use this flaw to either terminate TCP connection and/or inject payload into non-secured TCP connection between two endpoints on the network.(CVE-2016-5696)\n\n - A heap-based buffer overflow vulnerability was found in the Linux kernel's hiddev driver. This flaw could allow a local attacker to corrupt kernel memory, possible privilege escalation or crashing the system.(CVE-2016-5829)\n\n - When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands.(CVE-2016-6136)\n\n - It was found that the unlink and rename functionality in overlayfs did not verify the upper dentry for staleness. A local, unprivileged user could use the rename syscall on overlayfs on top of xfs to panic or crash the system.(CVE-2016-6197)\n\n - A flaw was found that the vfs_rename() function did not detect hard links on overlayfs. A local, unprivileged user could use the rename syscall on overlayfs on top of xfs to crash the system.(CVE-2016-6198)\n\n - System using the infiniband support module ib_srpt were vulnerable to a denial of service by system crash by a local attacker who is able to abort writes to a device using this initiator.(CVE-2016-6327)\n\n - A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation.\n A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value.(CVE-2016-6480)\n\n - kernel/events/core.c in the performance subsystem in the Linux kernel before 4.0 mismanages locks during certain migrations, which allows local users to gain privileges via a crafted application, aka Android internal bug 30955111.(CVE-2016-6786)\n\n - kernel/events/core.c in the performance subsystem in the Linux kernel before 4.0 mismanages locks during certain migrations, which allows local users to gain privileges via a crafted application, aka Android internal bug 31095224.(CVE-2016-6787)\n\n - A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and other tcp_* functions.\n This condition could allow an attacker to send an incorrect selective acknowledgment to existing connections, possibly resetting a connection.(CVE-2016-6828)\n\n - Linux kernel built with the 802.1Q/802.1ad VLAN(CONFIG_VLAN_8021Q) OR Virtual eXtensible Local Area Network(CONFIG_VXLAN) with Transparent Ethernet Bridging(TEB) GRO support, is vulnerable to a stack overflow issue. It could occur while receiving large packets via GRO path, as an unlimited recursion could unfold in both VLAN and TEB modules, leading to a stack corruption in the kernel.(CVE-2016-7039)\n\n - It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks.(CVE-2016-7042)\n\n - It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications.(CVE-2016-7097)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.
