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 flaw was found in the Linux kernel's keyring handling code, where in key_reject_and_link() an uninitialized variable would eventually lead to arbitrary free address which could allow attacker to use a use-after-free style attack. (CVE-2016-4470, Important)\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, Moderate)\n\nThe CVE-2016-4470 issue was discovered by David Howells (Red Hat Inc.).\n\nBug Fix(es) :\n\n* Previously, when two NFS shares with different security settings were mounted, the I/O operations to the kerberos-authenticated mount caused the RPC_CRED_KEY_EXPIRE_SOON parameter to be set, but the parameter was not unset when performing the I/O operations on the sec=sys mount. Consequently, writes to both NFS shares had the same parameters, regardless of their security settings. This update fixes this problem by moving the NO_CRKEY_TIMEOUT parameter to the auth->au_flags field. As a result, NFS shares with different security settings are now handled as expected. (BZ#1366962)\n\n* In some circumstances, resetting a Fibre Channel over Ethernet (FCoE) interface could lead to a kernel panic, due to invalid information extracted from the FCoE header. This update adds santiy checking to the cpu number extracted from the FCoE header. This ensures that subsequent operations address a valid cpu, and eliminates the kernel panic. (BZ#1359036)\n\n* Prior to this update, the following problems occurred with the way GSF2 transitioned files and directories from the 'unlinked' state to the 'free' state :\n\nThe numbers reported for the df and the du commands in some cases got out of sync, which caused blocks in the file system to appear missing.\nThe blocks were not actually missing, but they were left in the 'unlinked' state.\n\nIn some circumstances, GFS2 referenced a cluster lock that was already deleted, which led to a kernel panic.\n\nIf an object was deleted and its space reused as a different object, GFS2 sometimes deleted the existing one, which caused file system corruption.\n\nWith this update, the transition from 'unlinked' to 'free' state has been fixed. As a result, none of these three problems occur anymore.\n(BZ#1359037)\n\n* Previously, the GFS2 file system in some cases became unresponsive due to lock dependency problems between inodes and the cluster lock.\nThis occurred most frequently on nearly full file systems where files and directories were being deleted and recreated at the same block location at the same time. With this update, a set of patches has been applied to fix these lock dependencies. As a result, GFS2 no longer hangs in the described circumstances. (BZ#1359038)\n\n* When used with controllers that do not support DCMD- MR_DCMD_PD_LIST_QUERY, the megaraid_sas driver can go into infinite error reporting loop of error reporting messages. This could cause difficulties with finding other important log messages, or even it could cause the disk to overflow. This bug has been fixed by ignoring the DCMD MR_DCMD_PD_LIST_QUERY query for controllers which do not support it and sending the DCMD SUCCESS status to the AEN functions.\nAs a result, the error messages no longer appear when there is a change in the status of one of the arrays.

(CVE-2016-5829, Moderate)\n\nThe CVE-2016-4470 issue was discovered by David Howells (Red Hat Inc.).\n\nBug Fix(es) :\n\n* Previously, when two NFS shares with different security settings were mounted, the I/O operations to the kerberos-authenticated mount caused the RPC_CRED_KEY_EXPIRE_SOON parameter to be set, but the parameter was not unset when performing the I/O operations on the sec=sys mount. Consequently, writes to both NFS shares had the same parameters, regardless of their security settings. This update fixes this problem by moving the NO_CRKEY_TIMEOUT parameter to the auth->au_flags field. As a result, NFS shares with different security settings are now handled as expected. (BZ#1366962)\n\n* In some circumstances, resetting a Fibre Channel over Ethernet (FCoE) interface could lead to a kernel panic, due to invalid information extracted from the FCoE header. This update adds santiy checking to the cpu number extracted from the FCoE header. This ensures that subsequent operations address a valid cpu, and eliminates the kernel panic. (BZ#1359036)\n\n* Prior to this update, the following problems occurred with the way GSF2 transitioned files and directories from the 'unlinked' state to the 'free' state :\n\nThe numbers reported for the df and the du commands in some cases got out of sync, which caused blocks in the file system to appear missing.\nThe blocks were not actually missing, but they were left in the 'unlinked' state.\n\nIn some circumstances, GFS2 referenced a cluster lock that was already deleted, which led to a kernel panic.\n\nIf an object was deleted and its space reused as a different object, GFS2 sometimes deleted the existing one, which caused file system corruption.\n\nWith this update, the transition from 'unlinked' to 'free' state has been fixed. As a result, none of these three problems occur anymore.\n(BZ#1359037)\n\n* Previously, the GFS2 file system in some cases became unresponsive due to lock dependency problems between inodes and the cluster lock.\nThis occurred most frequently on nearly full file systems where files and directories were being deleted and recreated at the same block location at the same time. With this update, a set of patches has been applied to fix these lock dependencies. As a result, GFS2 no longer hangs in the described circumstances. (BZ#1359038)\n\n* When used with controllers that do not support DCMD- MR_DCMD_PD_LIST_QUERY, the megaraid_sas driver can go into infinite error reporting loop of error reporting messages. This could cause difficulties with finding other important log messages, or even it could cause the disk to overflow. This bug has been fixed by ignoring the DCMD MR_DCMD_PD_LIST_QUERY query for controllers which do not support it and sending the DCMD SUCCESS status to the AEN functions.\nAs a result, the error messages no longer appear when there is a change in the status of one of the arrays.

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 flaw was found in the Linux kernel's keyring handling code, where in key_reject_and_link() an uninitialized variable would eventually lead to arbitrary free address which could allow attacker to use a use-after-free style attack. (CVE-2016-4470, Important)\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, Moderate)\n\nThe CVE-2016-4470 issue was discovered by David Howells (Red Hat Inc.).\n\nBug Fix(es) :\n\n* Previously, when two NFS shares with different security settings were mounted, the I/O operations to the kerberos-authenticated mount caused the RPC_CRED_KEY_EXPIRE_SOON parameter to be set, but the parameter was not unset when performing the I/O operations on the sec=sys mount. Consequently, writes to both NFS shares had the same parameters, regardless of their security settings. This update fixes this problem by moving the NO_CRKEY_TIMEOUT parameter to the auth->au_flags field. As a result, NFS shares with different security settings are now handled as expected. (BZ#1366962)\n\n* In some circumstances, resetting a Fibre Channel over Ethernet (FCoE) interface could lead to a kernel panic, due to invalid information extracted from the FCoE header. This update adds santiy checking to the cpu number extracted from the FCoE header. This ensures that subsequent operations address a valid cpu, and eliminates the kernel panic. (BZ#1359036)\n\n* Prior to this update, the following problems occurred with the way GSF2 transitioned files and directories from the 'unlinked' state to the 'free' state :\n\nThe numbers reported for the df and the du commands in some cases got out of sync, which caused blocks in the file system to appear missing.\nThe blocks were not actually missing, but they were left in the 'unlinked' state.\n\nIn some circumstances, GFS2 referenced a cluster lock that was already deleted, which led to a kernel panic.\n\nIf an object was deleted and its space reused as a different object, GFS2 sometimes deleted the existing one, which caused file system corruption.\n\nWith this update, the transition from 'unlinked' to 'free' state has been fixed. As a result, none of these three problems occur anymore.\n(BZ#1359037)\n\n* Previously, the GFS2 file system in some cases became unresponsive due to lock dependency problems between inodes and the cluster lock.\nThis occurred most frequently on nearly full file systems where files and directories were being deleted and recreated at the same block location at the same time. With this update, a set of patches has been applied to fix these lock dependencies. As a result, GFS2 no longer hangs in the described circumstances. (BZ#1359038)\n\n* When used with controllers that do not support DCMD- MR_DCMD_PD_LIST_QUERY, the megaraid_sas driver can go into infinite error reporting loop of error reporting messages. This could cause difficulties with finding other important log messages, or even it could cause the disk to overflow. This bug has been fixed by ignoring the DCMD MR_DCMD_PD_LIST_QUERY query for controllers which do not support it and sending the DCMD SUCCESS status to the AEN functions.\nAs a result, the error messages no longer appear when there is a change in the status of one of the arrays.

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\nimpact of Important. 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 flaw was found in the Linux kernel's keyring handling code, where\nin key_reject_and_link() an uninitialized variable would eventually\nlead to arbitrary free address which could allow attacker to use a\nuse-after-free style attack. (CVE-2016-4470, Important)\n\n* A heap-based buffer overflow vulnerability was found in the Linux\nkernel's hiddev driver. This flaw could allow a local attacker to\ncorrupt kernel memory, possible privilege escalation or crashing the\nsystem. (CVE-2016-5829, Moderate)\n\nThe CVE-2016-4470 issue was discovered by David Howells (Red Hat\nInc.).\n\nBug Fix(es) :\n\n* Previously, when two NFS shares with different security settings\nwere mounted, the I/O operations to the kerberos-authenticated mount\ncaused the RPC_CRED_KEY_EXPIRE_SOON parameter to be set, but the\nparameter was not unset when performing the I/O operations on the\nsec=sys mount. Consequently, writes to both NFS shares had the same\nparameters, regardless of their security settings. This update fixes\nthis problem by moving the NO_CRKEY_TIMEOUT parameter to the\nauth->au_flags field. As a result, NFS shares with different security\nsettings are now handled as expected. (BZ#1366962)\n\n* In some circumstances, resetting a Fibre Channel over Ethernet\n(FCoE) interface could lead to a kernel panic, due to invalid\ninformation extracted from the FCoE header. This update adds santiy\nchecking to the cpu number extracted from the FCoE header. This\nensures that subsequent operations address a valid cpu, and eliminates\nthe kernel panic. (BZ#1359036)\n\n* Prior to this update, the following problems occurred with the way\nGSF2 transitioned files and directories from the 'unlinked' state to\nthe 'free' state :\n\nThe numbers reported for the df and the du commands in some cases got\nout of sync, which caused blocks in the file system to appear missing.\nThe blocks were not actually missing, but they were left in the\n'unlinked' state.\n\nIn some circumstances, GFS2 referenced a cluster lock that was already\ndeleted, which led to a kernel panic.\n\nIf an object was deleted and its space reused as a different object,\nGFS2 sometimes deleted the existing one, which caused file system\ncorruption.\n\nWith this update, the transition from 'unlinked' to 'free' state has\nbeen fixed. As a result, none of these three problems occur anymore.\n(BZ#1359037)\n\n* Previously, the GFS2 file system in some cases became unresponsive\ndue to lock dependency problems between inodes and the cluster lock.\nThis occurred most frequently on nearly full file systems where files\nand directories were being deleted and recreated at the same block\nlocation at the same time. With this update, a set of patches has been\napplied to fix these lock dependencies. As a result, GFS2 no longer\nhangs in the described circumstances. (BZ#1359038)\n\n* When used with controllers that do not support DCMD-\nMR_DCMD_PD_LIST_QUERY, the megaraid_sas driver can go into infinite\nerror reporting loop of error reporting messages. This could cause\ndifficulties with finding other important log messages, or even it\ncould cause the disk to overflow. This bug has been fixed by ignoring\nthe DCMD MR_DCMD_PD_LIST_QUERY query for controllers which do not\nsupport it and sending the DCMD SUCCESS status to the AEN functions.\nAs a result, the error messages no longer appear when there is a\nchange in the status of one of the arrays.

The\nblocks were not actually missing, but they were left in the 'unlinked'\nstate.\n\nIn some circumstances, GFS2 referenced a cluster lock that was already\ndeleted, which led to a kernel panic.\n\nIf an object was deleted and its space reused as a different object, GFS2\nsometimes deleted the existing one, which caused file system corruption.\n\nWith this update, the transition from 'unlinked' to 'free' state has been\nfixed.

This ensures that subsequent\noperations address a valid cpu, and eliminates the kernel panic.\n(BZ#1359036)\n\n* Prior to this update, the following problems occurred with the way GSF2\ntransitioned files and directories from the 'unlinked' state to the 'free'\nstate:\n\nThe numbers reported for the df and the du commands in some cases got out\nof sync, which caused blocks in the file system to appear missing. The\nblocks were not actually missing, but they were left in the 'unlinked'\nstate.\n\nIn some circumstances, GFS2 referenced a cluster lock that was already\ndeleted, which led to a kernel panic.\n\nIf an object was deleted and its space reused as a different object, GFS2\nsometimes deleted the existing one, which caused file system corruption.\n\nWith this update, the transition from 'unlinked' to 'free' state has been\nfixed. As a result, none of these three problems occur anymore.\n(BZ#1359037)\n\n* Previously, the GFS2 file system in some cases became unresponsive due to\nlock dependency problems between inodes and the cluster lock.

Space precludes documenting\nall of these bug fixes in this advisory. To see the complete list of bug\nfixes, users are directed to the related Knowledge Article:\n'https://access.redhat.com/articles/2460971'.\n\nSecurity Fix(es):\n\n* A flaw was found in the Linux kernel's keyring handling code, where in\nkey_reject_and_link() an uninitialised variable would eventually lead to\narbitrary free address which could allow attacker to use a use-after-free\nstyle attack. (CVE-2016-4470, Important)\n\n* The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel\nthrough 4.3.3 attempts to merge distinct setattr operations, which allows\nlocal users to bypass intended access restrictions and modify the\nattributes of arbitrary overlay files via a crafted application.\n(CVE-2015-8660, Moderate)\n\n* It was reported that on s390x, the fork of a process with four page table\nlevels will cause memory corruption with a variety of symptoms. All\nprocesses are created with three level page table and a limit of 4TB for\nthe address space. If the parent process has four page table levels with a\nlimit of 8PB, the function that duplicates the address space will try to\ncopy memory areas outside of the address space limit for the child process.\n(CVE-2016-2143, Moderate)\n\nRed Hat would like to thank Nathan Williams for reporting CVE-2015-8660.\nThe CVE-2016-4470 issue was discovered by David Howells (Red Hat Inc.).\n\nBug Fix(es):\n\n* The glibc headers and the Linux headers share certain definitions of\nkey structures that are required to be defined in kernel and in userspace.\nIn some instances both userspace and sanitized kernel headers have to be\nincluded in order to get the structure definitions required by the user\nprogram.

All\nprocesses are created with three level page table and a limit of 4TB for\nthe address space. If the parent process has four page table levels with a\nlimit of 8PB, the function that duplicates the address space will try to\ncopy memory areas outside of the address space limit for the child process.\n(CVE-2016-2143, Moderate)\n\nRed Hat would like to thank Nathan Williams for reporting CVE-2015-8660.\nThe CVE-2016-4470 issue was discovered by David Howells (Red Hat Inc.).\n\nBug Fix(es):\n\n * The glibc headers and the Linux headers share certain definitions of\nkey structures that are required to be defined in kernel and in userspace.\nIn some instances both userspace and sanitized kernel headers have to be\nincluded in order to get the structure definitions required by the user\nprogram.

This flaw could allow a local attacker to\ncorrupt kernel memory, possible privilege escalation or crashing the\nsystem. (CVE-2016-5829, Moderate)\n\nThe CVE-2016-4470 issue was discovered by David Howells (Red Hat\nInc.).\n\nBug Fix(es) :\n\n* Previously, when two NFS shares with different security settings\nwere mounted, the I/O operations to the kerberos-authenticated mount\ncaused the RPC_CRED_KEY_EXPIRE_SOON parameter to be set, but the\nparameter was not unset when performing the I/O operations on the\nsec=sys mount. Consequently, writes to both NFS shares had the same\nparameters, regardless of their security settings. This update fixes\nthis problem by moving the NO_CRKEY_TIMEOUT parameter to the\nauth->au_flags field. As a result, NFS shares with different security\nsettings are now handled as expected. (BZ# 1366962)\n\n* In some circumstances, resetting a Fibre Channel over Ethernet\n(FCoE) interface could lead to a kernel panic, due to invalid\ninformation extracted from the FCoE header. This update adds santiy\nchecking to the cpu number extracted from the FCoE header. This\nensures that subsequent operations address a valid cpu, and eliminates\nthe kernel panic. (BZ# 1359036)\n\n* Prior to this update, the following problems occurred with the way\nGSF2 transitioned files and directories from the 'unlinked' state to\nthe 'free' state :\n\nThe numbers reported for the df and the du commands in some cases got\nout of sync, which caused blocks in the file system to appear missing.\nThe blocks were not actually missing, but they were left in the\n'unlinked' state.\n\nIn some circumstances, GFS2 referenced a cluster lock that was already\ndeleted, which led to a kernel panic.\n\nIf an object was deleted and its space reused as a different object,\nGFS2 sometimes deleted the existing one, which caused file system\ncorruption.\n\nWith this update, the transition from 'unlinked' to 'free' state has\nbeen fixed. As a result, none of these three problems occur anymore.\n(BZ#1359037)\n\n* Previously, the GFS2 file system in some cases became unresponsive\ndue to lock dependency problems between inodes and the cluster lock.\nThis occurred most frequently on nearly full file systems where files\nand directories were being deleted and recreated at the same block\nlocation at the same time. With this update, a set of patches has been\napplied to fix these lock dependencies. As a result, GFS2 no longer\nhangs in the described circumstances. (BZ#1359038)\n\n* When used with controllers that do not support DCMD-\nMR_DCMD_PD_LIST_QUERY, the megaraid_sas driver can go into infinite\nerror reporting loop of error reporting messages. This could cause\ndifficulties with finding other important log messages, or even it\ncould cause the disk to overflow. This bug has been fixed by ignoring\nthe DCMD MR_DCMD_PD_LIST_QUERY query for controllers which do not\nsupport it and sending the DCMD SUCCESS status to the AEN functions.\nAs a result, the error messages no longer appear when there is a\nchange in the status of one of the arrays.

(CVE-2016-5829, Moderate)\n\nThe CVE-2016-4470 issue was discovered by David Howells (Red Hat\nInc.).\n\nBug Fix(es) :\n\n* Previously, when two NFS shares with different security settings\nwere mounted, the I/O operations to the kerberos-authenticated mount\ncaused the RPC_CRED_KEY_EXPIRE_SOON parameter to be set, but the\nparameter was not unset when performing the I/O operations on the\nsec=sys mount. Consequently, writes to both NFS shares had the same\nparameters, regardless of their security settings. This update fixes\nthis problem by moving the NO_CRKEY_TIMEOUT parameter to the\nauth->au_flags field. As a result, NFS shares with different security\nsettings are now handled as expected. (BZ# 1366962)\n\n* In some circumstances, resetting a Fibre Channel over Ethernet\n(FCoE) interface could lead to a kernel panic, due to invalid\ninformation extracted from the FCoE header. This update adds santiy\nchecking to the cpu number extracted from the FCoE header. This\nensures that subsequent operations address a valid cpu, and eliminates\nthe kernel panic. (BZ# 1359036)\n\n* Prior to this update, the following problems occurred with the way\nGSF2 transitioned files and directories from the 'unlinked' state to\nthe 'free' state :\n\nThe numbers reported for the df and the du commands in some cases got\nout of sync, which caused blocks in the file system to appear missing.\nThe blocks were not actually missing, but they were left in the\n'unlinked' state.\n\nIn some circumstances, GFS2 referenced a cluster lock that was already\ndeleted, which led to a kernel panic.\n\nIf an object was deleted and its space reused as a different object,\nGFS2 sometimes deleted the existing one, which caused file system\ncorruption.\n\nWith this update, the transition from 'unlinked' to 'free' state has\nbeen fixed. As a result, none of these three problems occur anymore.\n(BZ#1359037)\n\n* Previously, the GFS2 file system in some cases became unresponsive\ndue to lock dependency problems between inodes and the cluster lock.\nThis occurred most frequently on nearly full file systems where files\nand directories were being deleted and recreated at the same block\nlocation at the same time. With this update, a set of patches has been\napplied to fix these lock dependencies. As a result, GFS2 no longer\nhangs in the described circumstances. (BZ#1359038)\n\n* When used with controllers that do not support DCMD-\nMR_DCMD_PD_LIST_QUERY, the megaraid_sas driver can go into infinite\nerror reporting loop of error reporting messages. This could cause\ndifficulties with finding other important log messages, or even it\ncould cause the disk to overflow. This bug has been fixed by ignoring\nthe DCMD MR_DCMD_PD_LIST_QUERY query for controllers which do not\nsupport it and sending the DCMD SUCCESS status to the AEN functions.\nAs a result, the error messages no longer appear when there is a\nchange in the status of one of the arrays.

(CVE-2016-4470, Important)\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, Moderate)\n\nThe CVE-2016-4470 issue was discovered by David Howells (Red Hat Inc.).\n\nBug Fix(es):\n\n* Previously, when two NFS shares with different security settings were mounted, the I/O operations to the kerberos-authenticated mount caused the RPC_CRED_KEY_EXPIRE_SOON parameter to be set, but the parameter was not unset when performing the I/O operations on the sec=sys mount. Consequently, writes to both NFS shares had the same parameters, regardless of their security settings. This update fixes this problem by moving the NO_CRKEY_TIMEOUT parameter to the auth->au_flags field. As a result, NFS shares with different security settings are now handled as expected. (BZ#1366962)\n\n* In some circumstances, resetting a Fibre Channel over Ethernet (FCoE) interface could lead to a kernel panic, due to invalid information extracted from the FCoE header. This update adds santiy checking to the cpu number extracted from the FCoE header. This ensures that subsequent operations address a valid cpu, and eliminates the kernel panic. (BZ#1359036)\n\n* Prior to this update, the following problems occurred with the way GSF2 transitioned files and directories from the \"unlinked\" state to the \"free\" state:\n\nThe numbers reported for the df and the du commands in some cases got out of sync, which caused blocks in the file system to appear missing. The blocks were not actually missing, but they were left in the \"unlinked\" state.\n\nIn some circumstances, GFS2 referenced a cluster lock that was already deleted, which led to a kernel panic.\n\nIf an object was deleted and its space reused as a different object, GFS2 sometimes deleted the existing one, which caused file system corruption.\n\nWith this update, the transition from \"unlinked\" to \"free\" state has been fixed. As a result, none of these three problems occur anymore. (BZ#1359037)\n\n* Previously, the GFS2 file system in some cases became unresponsive due to lock dependency problems between inodes and the cluster lock. This occurred most frequently on nearly full file systems where files and directories were being deleted and recreated at the same block location at the same time. With this update, a set of patches has been applied to fix these lock dependencies. As a result, GFS2 no longer hangs in the described circumstances. (BZ#1359038)\n\n* When used with controllers that do not support DCMD- MR_DCMD_PD_LIST_QUERY, the megaraid_sas driver can go into infinite error reporting loop of error reporting messages. This could cause difficulties with finding other important log messages, or even it could cause the disk to overflow. This bug has been fixed by ignoring the DCMD MR_DCMD_PD_LIST_QUERY query for controllers which do not support it and sending the DCMD SUCCESS status to the AEN functions. As a result, the error messages no longer appear when there is a change in the status of one of the arrays.

This flaw could allow a local attacker to corrupt kernel memory, possible privilege escalation or crashing the system. (CVE-2016-5829, Moderate)\n\nThe CVE-2016-4470 issue was discovered by David Howells (Red Hat Inc.).\n\nBug Fix(es):\n\n* Previously, when two NFS shares with different security settings were mounted, the I/O operations to the kerberos-authenticated mount caused the RPC_CRED_KEY_EXPIRE_SOON parameter to be set, but the parameter was not unset when performing the I/O operations on the sec=sys mount. Consequently, writes to both NFS shares had the same parameters, regardless of their security settings. This update fixes this problem by moving the NO_CRKEY_TIMEOUT parameter to the auth->au_flags field. As a result, NFS shares with different security settings are now handled as expected. (BZ#1366962)\n\n* In some circumstances, resetting a Fibre Channel over Ethernet (FCoE) interface could lead to a kernel panic, due to invalid information extracted from the FCoE header. This update adds santiy checking to the cpu number extracted from the FCoE header. This ensures that subsequent operations address a valid cpu, and eliminates the kernel panic. (BZ#1359036)\n\n* Prior to this update, the following problems occurred with the way GSF2 transitioned files and directories from the \"unlinked\" state to the \"free\" state:\n\nThe numbers reported for the df and the du commands in some cases got out of sync, which caused blocks in the file system to appear missing. The blocks were not actually missing, but they were left in the \"unlinked\" state.\n\nIn some circumstances, GFS2 referenced a cluster lock that was already deleted, which led to a kernel panic.\n\nIf an object was deleted and its space reused as a different object, GFS2 sometimes deleted the existing one, which caused file system corruption.\n\nWith this update, the transition from \"unlinked\" to \"free\" state has been fixed. As a result, none of these three problems occur anymore. (BZ#1359037)\n\n* Previously, the GFS2 file system in some cases became unresponsive due to lock dependency problems between inodes and the cluster lock. This occurred most frequently on nearly full file systems where files and directories were being deleted and recreated at the same block location at the same time. With this update, a set of patches has been applied to fix these lock dependencies. As a result, GFS2 no longer hangs in the described circumstances. (BZ#1359038)\n\n* When used with controllers that do not support DCMD- MR_DCMD_PD_LIST_QUERY, the megaraid_sas driver can go into infinite error reporting loop of error reporting messages. This could cause difficulties with finding other important log messages, or even it could cause the disk to overflow. This bug has been fixed by ignoring the DCMD MR_DCMD_PD_LIST_QUERY query for controllers which do not support it and sending the DCMD SUCCESS status to the AEN functions. As a result, the error messages no longer appear when there is a change in the status of one of the arrays.

The\n OABI compatibility layer is enabled in all kernel flavours for\n armel and armhf.\n\nCVE-2016-4470\n\n Wade Mealing of the Red Hat Product Security Team reported that\n in some error cases the KEYS subsystem will dereference an\n uninitialised pointer. A local user can use the keyctl()\n system call for denial of service (crash) or possibly for\n privilege escalation.\n\nCVE-2016-5696\n\n Yue Cao, Zhiyun Qian, Zhongjie Wang, Tuan Dao, and Srikanth V.\n Krishnamurthy of the University of California, Riverside; and Lisa\n M. Marvel of the United States Army Research Laboratory discovered\n that Linux&#x27;s implementation of the TCP Challenge ACK feature\n results in a side channel that can be used to find TCP connections\n between specific IP addresses, and to inject messages into those\n connections.\n\n Where a service is made available through TCP, this may allow\n remote attackers to impersonate another connected user to the\n server or to impersonate the server to another connected user. In\n case the service uses a protocol with message authentication\n (e.g. TLS or SSH), this vulnerability only allows denial of\n service (connection failure). An attack takes tens of seconds, so\n short-lived TCP connections are also unlikely to be vulnerable.\n\n This may be mitigated by increasing the rate limit for TCP\n Challenge ACKs so that it is never exceeded:\n sysctl net.ipv4.tcp_challenge_ack_limit=1000000000\n\nCVE-2016-5829\n\n Several heap-based buffer overflow vulnerabilities were found in\n the hiddev driver, allowing a local user with access to a HID\n device to cause a denial of service or potentially escalate their\n privileges.\n\nCVE-2016-6136\n\n Pengfei Wang discovered that the audit subsystem has a\n &#x27;double-fetch&#x27; or &#x27;TOCTTOU&#x27; bug in its handling of special\n characters in the name of an executable. Where audit logging of\n execve() is enabled, this allows a local user to generate\n misleading log messages.\n\nCVE-2016-6480\n\n Pengfei Wang discovered that the aacraid driver for Adaptec RAID\n controllers has a &#x27;double-fetch&#x27; or &#x27;TOCTTOU&#x27; bug in its\n validation of &#x27;FIB&#x27; messages passed through the ioctl() system\n call. This has no practical security impact in current Debian\n releases.\n\nCVE-2016-6828\n\n Marco Grassi reported a &#x27;use-after-free&#x27; bug in the TCP\n implementation, which can be triggered by local users. The\n security impact is unclear, but might include denial of service or\n privilege escalation.\n\nCVE-2016-7118\n\n Marcin Szewczyk reported that calling fcntl() on a file descriptor\n for a directory on an aufs filesystem would result in am &#x27;oops&#x27;.\n This allows local users to cause a denial of service. This is a\n Debian-specific regression introduced in version 3.2.81-1.\n\nFor Debian 7 &quot;Wheezy&quot;, these problems have been fixed in version\n3.2.81-2. This version also fixes a build failure (bug #827561) for\ncustom kernels with CONFIG_MODULES disabled, a regression in version\n3.2.81-1. It also updates the PREEMPT_RT featureset to version\n3.2.81-rt117.\n\nFor Debian 8 &quot;Jessie&quot;, CVE-2016-3857 has no impact; CVE-2016-4470 and\nCVE-2016-5829 were fixed in linux version 3.16.7-ckt25-2+deb8u3 or\nearlier; and the remaining issues are fixed in version 3.16.36-1+deb8u1.\n\nWe recommend that you upgrade your linux packages.\n\nFurther information about Debian LTS security advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://wiki.debian.org/LTS\n\n-- \nBen Hutchings - Debian developer, member of kernel, installer and LTS teams", "modified": "2016-09-03T11:54:21", "published": "2016-09-03T11:54:21", "id": "DEBIAN:DLA-609-1:1025A", "href": "https://lists.debian.org/debian-lts-announce/2016/debian-lts-announce-201609/msg00002.html", "title": "[SECURITY] [DLA 609-1] linux security update", "type": "debian", "cvss": {"score": 9.3, "vector": "AV:NETWORK/AC:MEDIUM/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}]}
