    description Updated kernel packages that fix two security issues and one bug are now available for Red Hat Enterprise Linux 5.6 Extended Update Support. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * A flaw was found in the way socket buffers (skb) requiring TSO (TCP segment offloading) were handled by the sfc driver. If the skb did not fit within the minimum-size of the transmission queue, the network card could repeatedly reset itself. A remote attacker could use this flaw to cause a denial of service. (CVE-2012-3412, Important) * A buffer overflow flaw was found in the hfs_bnode_read() function in the HFS Plus (HFS+) file system implementation in the Linux kernel. A local user able to mount a specially crafted HFS+ file system image could use this flaw to cause a denial of service or escalate their privileges. (CVE-2012-2319, Low) Red Hat would like to thank Ben Hutchings of Solarflare (tm) for reporting CVE-2012-3412. This update also fixes the following bug : * Some subsystems clear the TIF_SIGPENDING flag during error handling in fork() paths. Previously, if the flag was cleared, the ERESTARTNOINTR error code could be returned. The underlying source code has been modified so that the error code is no longer returned. (BZ#855754) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

    NASL id SUSE_11_KERNEL-121203.NASL
    description The SUSE Linux Enterprise 11 SP2 kernel has been updated to 3.0.51 which fixes various bugs and security issues. It contains the following feature enhancements : - The cachefiles framework is now supported (FATE#312793, bnc#782369). The userland utilities were published seperately to support this feature. - The ipset netfilter modules are now supported (FATE#313309) The ipset userland utility will be published seperately to support this feature. - The tipc kernel module is now externally supported (FATE#305033). - Hyper-V KVP IP injection was implemented (FATE#314441). A seperate hyper-v package will be published to support this feature. - Intel Lynx Point PCH chipset support was added. (FATE#313409) - Enable various md/raid10 and DASD enhancements. (FATE#311379) These make it possible for RAID10 to cope with DASD devices being slow for various reasons - the affected device will be temporarily removed from the array. Also added support for reshaping of RAID10 arrays. mdadm changes will be published to support this feature. The following security issues have been fixed : - A race condition on hot adding memory could be used by local attackers to crash the system during hot adding new memory. (CVE-2012-5517) - A flaw has been found in the way Linux kernels KVM subsystem handled vcpu->arch.cr4 X86_CR4_OSXSAVE bit set upon guest enter. On hosts without the XSAVE feature and using qemu userspace an unprivileged local user could have used this flaw to crash the system. (CVE-2012-4461) - The KVM implementation in the Linux kernel allowed host OS users to cause a denial of service (NULL pointer dereference and host OS crash) by making a KVM_CREATE_IRQCHIP ioctl call after a virtual CPU already exists. (CVE-2012-1601) - Attempting an rds connection from the IP address of an IPoIB interface to itself causes a kernel panic due to a BUG_ON() being triggered. Making the test less strict allows rds-ping to work without crashing the machine. A local unprivileged user could use this flaw to crash the sytem. (CVE-2012-2372) - Dimitry Monakhov, one of the ext4 developers, has discovered a race involving asynchronous I/O and fallocate which can lead to the exposure of stale data --- that is, an extent which should have had the 'uninitialized' bit set indicating that its blocks have not yet been written and thus contain data from a deleted file will get exposed to anyone with read access to the file. (CVE-2012-4508) - The rds_recvmsg function in net/rds/recv.c in the Linux kernel did not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a (1) recvfrom or (2) recvmsg system call on an RDS socket.

  • NASL family Ubuntu Local Security Checks
    NASL id UBUNTU_USN-1573-1.NASL
    description Ben Hutchings reported a flaw in the Linux kernel with some network drivers that support TSO (TCP segment offload). A local or peer user could exploit this flaw to to cause a denial of service. (CVE-2012-3412) Jay Fenlason and Doug Ledford discovered a bug in the Linux kernel implementation of RDS sockets. A local unprivileged user could potentially use this flaw to read privileged information from the kernel. (CVE-2012-3430) A flaw was discovered in the madvise feature of the Linux kernel's memory subsystem. An unprivileged local use could exploit the flaw to cause a denial of service (crash the system). (CVE-2012-3511). 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.

  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2012-1323.NASL
    description Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * A flaw was found in the way socket buffers (skb) requiring TSO (TCP segment offloading) were handled by the sfc driver. If the skb did not fit within the minimum-size of the transmission queue, the network card could repeatedly reset itself. A remote attacker could use this flaw to cause a denial of service. (CVE-2012-3412, Important) * A use-after-free flaw was found in the xacct_add_tsk() function in the Linux kernel's taskstats subsystem. A local, unprivileged user could use this flaw to cause an information leak or a denial of service. (CVE-2012-3510, Moderate) * A buffer overflow flaw was found in the hfs_bnode_read() function in the HFS Plus (HFS+) file system implementation in the Linux kernel. A local user able to mount a specially crafted HFS+ file system image could use this flaw to cause a denial of service or escalate their privileges. (CVE-2012-2319, Low) * A flaw was found in the way the msg_namelen variable in the rds_recvmsg() function of the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation was initialized. A local, unprivileged user could use this flaw to leak kernel stack memory to user-space. (CVE-2012-3430, Low) Red Hat would like to thank Ben Hutchings of Solarflare (tm) for reporting CVE-2012-3412, and Alexander Peslyak for reporting CVE-2012-3510. The CVE-2012-3430 issue was discovered by the Red Hat InfiniBand team. This update also fixes the following bugs : * The cpuid_whitelist() function, masking the Enhanced Intel SpeedStep (EST) flag from all guests, prevented the 'cpuspeed' service from working in the privileged Xen domain (dom0). CPU scaling was therefore not possible. With this update, cpuid_whitelist() is aware whether the domain executing CPUID is privileged or not, and enables the EST flag for dom0. (BZ#846125) * If a delayed-allocation write was performed before quota was enabled, the kernel displayed the following warning message : WARNING: at fs/quota/dquot.c:988 dquot_claim_space+0x77/0x112() This was because information about the delayed allocation was not recorded in the quota structure. With this update, writes prior to enabling quota are properly accounted for, and the message is not displayed. (BZ#847326) * In Red Hat Enterprise Linux 5.9, the DSCP (Differentiated Services Code Point) netfilter module now supports mangling of the DSCP field. (BZ#847327) * Some subsystems clear the TIF_SIGPENDING flag during error handling in fork() paths. Previously, if the flag was cleared, the ERESTARTNOINTR error code could be returned. The underlying source code has been modified so that the error code is no longer returned. (BZ#847359) * An unnecessary check for the RXCW.CW bit could cause the Intel e1000e NIC (Network Interface Controller) to not work properly. The check has been removed so that the Intel e1000e NIC works as expected. (BZ#852448) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

CVE-2013-0160: Avoid a side channel attack on /dev/ptmx (keyboard input timing). CVE-2012-5374: Fixed a local denial of service in the BTRFS hashing code. CVE-2013-0309: arch/x86/include/asm/pgtable.h in the Linux kernel, when transparent huge pages are used, does not properly support PROT_NONE memory regions, which allows local users to cause a denial of service (system crash) via a crafted application. CVE-2013-0268: The msr_open function in arch/x86/kernel/msr.c in the Linux kernel allowed local users to bypass intended capability restrictions by executing a crafted application as root, as demonstrated by msr32.c. CVE-2012-0957: The override_release function in kernel/sys.c in the Linux kernel allowed local users to obtain sensitive information from kernel stack memory via a uname system call in conjunction with a UNAME26 personality. CVE-2013-0216: The Xen netback functionality in the Linux kernel allowed guest OS users to cause a denial of service (loop) by triggering ring pointer corruption. CVE-2013-0231: The pciback_enable_msi function in the PCI backend driver (drivers/xen/pciback/conf_space_capability_msi.c) in Xen for the Linux kernel allowed guest OS users with PCI device access to cause a denial of service via a large number of kernel log messages. NOTE: some of these details are obtained from third-party information. CVE-2012-4530: The load_script function in fs/binfmt_script.c in the Linux kernel did not properly handle recursion, which allowed local users to obtain sensitive information from kernel stack memory via a crafted application. CVE-2012-4508: Race condition in fs/ext4/extents.c in the Linux kernel allowed local users to obtain sensitive information from a deleted file by reading an extent that was not properly marked as uninitialized. CVE-2012-3412: The sfc (aka Solarflare Solarstorm) driver in the Linux kernel allowed remote attackers to cause a denial of service (DMA descriptor consumption and network-controller outage) via crafted TCP packets that trigger a small MSS value. CVE-2012-2745: The copy_creds function in kernel/cred.c in the Linux kernel provided an invalid replacement session keyring to a child process, which allowed local users to cause a denial of service (panic) via a crafted application that uses the fork system call. CVE-2012-3375: The epoll_ctl system call in fs/eventpoll.c in the Linux kernel did not properly handle ELOOP errors in EPOLL_CTL_ADD operations, which allowed local users to cause a denial of service (file-descriptor consumption and system crash) via a crafted application that attempts to create a circular epoll dependency. CVE-2012-3400: Heap-based buffer overflow in the udf_load_logicalvol function in fs/udf/super.c in the Linux kernel allowed remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted UDF filesystem.

    title openSUSE Security Update : kernel (openSUSE-SU-2013:0396-1)
  • NASL family CentOS Local Security Checks
    NASL id CENTOS_RHSA-2012-1323.NASL
    description Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * A flaw was found in the way socket buffers (skb) requiring TSO (TCP segment offloading) were handled by the sfc driver. If the skb did not fit within the minimum-size of the transmission queue, the network card could repeatedly reset itself. A remote attacker could use this flaw to cause a denial of service. (CVE-2012-3412, Important) * A use-after-free flaw was found in the xacct_add_tsk() function in the Linux kernel's taskstats subsystem. A local, unprivileged user could use this flaw to cause an information leak or a denial of service. (CVE-2012-3510, Moderate) * A buffer overflow flaw was found in the hfs_bnode_read() function in the HFS Plus (HFS+) file system implementation in the Linux kernel. A local user able to mount a specially crafted HFS+ file system image could use this flaw to cause a denial of service or escalate their privileges. (CVE-2012-2319, Low) * A flaw was found in the way the msg_namelen variable in the rds_recvmsg() function of the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation was initialized. A local, unprivileged user could use this flaw to leak kernel stack memory to user-space. (CVE-2012-3430, Low) Red Hat would like to thank Ben Hutchings of Solarflare (tm) for reporting CVE-2012-3412, and Alexander Peslyak for reporting CVE-2012-3510. The CVE-2012-3430 issue was discovered by the Red Hat InfiniBand team. This update also fixes the following bugs : * The cpuid_whitelist() function, masking the Enhanced Intel SpeedStep (EST) flag from all guests, prevented the 'cpuspeed' service from working in the privileged Xen domain (dom0). CPU scaling was therefore not possible. With this update, cpuid_whitelist() is aware whether the domain executing CPUID is privileged or not, and enables the EST flag for dom0. (BZ#846125) * If a delayed-allocation write was performed before quota was enabled, the kernel displayed the following warning message : WARNING: at fs/quota/dquot.c:988 dquot_claim_space+0x77/0x112() This was because information about the delayed allocation was not recorded in the quota structure. With this update, writes prior to enabling quota are properly accounted for, and the message is not displayed. (BZ#847326) * In Red Hat Enterprise Linux 5.9, the DSCP (Differentiated Services Code Point) netfilter module now supports mangling of the DSCP field. (BZ#847327) * Some subsystems clear the TIF_SIGPENDING flag during error handling in fork() paths. Previously, if the flag was cleared, the ERESTARTNOINTR error code could be returned. The underlying source code has been modified so that the error code is no longer returned. (BZ#847359) * An unnecessary check for the RXCW.CW bit could cause the Intel e1000e NIC (Network Interface Controller) to not work properly. The check has been removed so that the Intel e1000e NIC works as expected. (BZ#852448) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

    NASL id REDHAT-RHSA-2012-1401.NASL
    description Updated kernel packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6.2 Extended Update Support. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issue : * A flaw was found in the way socket buffers (skb) requiring TSO (TCP segment offloading) were handled by the sfc driver. If the skb did not fit within the minimum-size of the transmission queue, the network card could repeatedly reset itself. A remote attacker could use this flaw to cause a denial of service. (CVE-2012-3412, Important) Red Hat would like to thank Ben Hutchings of Solarflare (tm) for reporting CVE-2012-3412. This update also fixes the following bugs : * Previously, when a server attempted to shut down a socket, the svc_tcp_sendto() function set the XPT_CLOSE variable if the entire reply failed to be transmitted. However, before XPT_CLOSE could be acted upon, other threads could send further replies before the socket was really shut down. Consequently, data corruption could occur in the RPC record marker. With this update, send operations on a closed socket are stopped immediately, thus preventing this bug. (BZ#853256) * When a PIT (Programmable Interval Timer) MSB (Most Significant Byte) transition occurred very close to an SMI (System Management Interrupt) execution, the pit_verify_msb() function did not see the MSB transition. Consequently, the pit_expect_msb() function returned success incorrectly, eventually causing a large clock drift in the quick_pit_calibrate() function. As a result, the TSC (Time Stamp Counter) calibration on some systems was off by +- 20 MHz, which led to inaccurate timekeeping or ntp synchronization failures. This update fixes pit_expect_msb() and the clock drift no longer occurs in the described scenario. (BZ#853952) * Sometimes, the crypto allocation code could become unresponsive for 60 seconds or multiples thereof due to an incorrect notification mechanism. This could cause applications, like Openswan, to become unresponsive. The notification mechanism has been improved to avoid such hangs. (BZ#854475) * Traffic to the NFS server could trigger a kernel oops in the svc_tcp_clear_pages() function. The source code has been modified, and the kernel oops no longer occurs in this scenario. (BZ#856105) * Under certain circumstances, a system crash could result in data loss on XFS file systems. If files were created immediately before the file system was left to idle for a long period of time and then the system crashed, those files could appear as zero-length once the file system was remounted. This occurred even if a sync or fsync was run on the files. This was because XFS was not correctly idling the journal, and therefore it incorrectly replayed the inode allocation transactions upon mounting after the system crash, which zeroed the file size. This problem has been fixed by re-instating the periodic journal idling logic to ensure that all metadata is flushed within 30 seconds of modification, and the journal is updated to prevent incorrect recovery operations from occurring. (BZ#856685) * On architectures with the 64-bit cputime_t type, it was possible to trigger the 'divide by zero' error, namely, on long-lived processes. A patch has been applied to address this problem, and the 'divide by zero' error no longer occurs under these circumstances. (BZ#856702) Users should upgrade to these updated packages, which contain backported patches to resolve these issues. The system must be rebooted for this update to take effect.

    description Updated kernel packages that fix one security issue and three bugs are now available for Red Hat Enterprise Linux 6.1 Extended Update Support. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system.

(CVE-2012-3412, Important) Red Hat would like to thank Ben Hutchings of Solarflare (tm) for reporting this issue. This update also fixes the following bugs : * In the hpet_next_event() function, an interrupt could have occurred between the read and write of the HPET (High Precision Event Timer) and the value of HPET_COUNTER was then beyond that being written to the comparator (HPET_Tn_CMP). Consequently, the timers were overdue for up to several minutes. Now, a comparison is performed between the value of the counter and the comparator in the HPET code. If the counter is beyond the comparator, the '-ETIME' error code is returned, which fixes this bug. (BZ#855280) * Traffic to the NFS server could trigger a kernel oops in the svc_tcp_clear_pages() function. The source code has been modified, and the kernel oops no longer occurs in this scenario. (BZ#856104) * A kernel oops occurred in the nf_nat code when a bogus pointer was dereferenced in the nf_conn_nat structure. Consequently, if Source Network Address Translation (SNAT) was performed, incorrect information could be received by other CTS (Clear to Send) signals. A conntrack entry is now placed in the source hash after SNAT has been completed, which prevents the described problems. (BZ#865714) Users should upgrade to these updated packages, which contain backported patches to resolve these issues. The system must be rebooted for this update to take effect.

(CVE-2012-3412, Important) Red Hat would like to thank Ben Hutchings of Solarflare (tm) for reporting this issue. This update also fixes several bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. Users should upgrade to these updated packages, which contain backported patches to correct this issue, and fix the bugs noted in the Technical Notes. The system must be rebooted for this update to take effect.

    description From Red Hat Security Advisory 2012:1323 : Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * A flaw was found in the way socket buffers (skb) requiring TSO (TCP segment offloading) were handled by the sfc driver. If the skb did not fit within the minimum-size of the transmission queue, the network card could repeatedly reset itself. A remote attacker could use this flaw to cause a denial of service. (CVE-2012-3412, Important) * A use-after-free flaw was found in the xacct_add_tsk() function in the Linux kernel's taskstats subsystem. A local, unprivileged user could use this flaw to cause an information leak or a denial of service. (CVE-2012-3510, Moderate) * A buffer overflow flaw was found in the hfs_bnode_read() function in the HFS Plus (HFS+) file system implementation in the Linux kernel. A local user able to mount a specially crafted HFS+ file system image could use this flaw to cause a denial of service or escalate their privileges. (CVE-2012-2319, Low) * A flaw was found in the way the msg_namelen variable in the rds_recvmsg() function of the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation was initialized. A local, unprivileged user could use this flaw to leak kernel stack memory to user-space. (CVE-2012-3430, Low) Red Hat would like to thank Ben Hutchings of Solarflare (tm) for reporting CVE-2012-3412, and Alexander Peslyak for reporting CVE-2012-3510. The CVE-2012-3430 issue was discovered by the Red Hat InfiniBand team. This update also fixes the following bugs : * The cpuid_whitelist() function, masking the Enhanced Intel SpeedStep (EST) flag from all guests, prevented the 'cpuspeed' service from working in the privileged Xen domain (dom0). CPU scaling was therefore not possible. With this update, cpuid_whitelist() is aware whether the domain executing CPUID is privileged or not, and enables the EST flag for dom0. (BZ#846125) * If a delayed-allocation write was performed before quota was enabled, the kernel displayed the following warning message : WARNING: at fs/quota/dquot.c:988 dquot_claim_space+0x77/0x112() This was because information about the delayed allocation was not recorded in the quota structure. With this update, writes prior to enabling quota are properly accounted for, and the message is not displayed. (BZ#847326) * In Red Hat Enterprise Linux 5.9, the DSCP (Differentiated Services Code Point) netfilter module now supports mangling of the DSCP field. (BZ#847327) * Some subsystems clear the TIF_SIGPENDING flag during error handling in fork() paths. Previously, if the flag was cleared, the ERESTARTNOINTR error code could be returned. The underlying source code has been modified so that the error code is no longer returned. (BZ#847359) * An unnecessary check for the RXCW.CW bit could cause the Intel e1000e NIC (Network Interface Controller) to not work properly. The check has been removed so that the Intel e1000e NIC works as expected. (BZ#852448) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

    description An updated rhev-hypervisor6 package that fixes one security issue and one bug is now available. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. A flaw was found in the way socket buffers (skb) requiring TSO (TCP segment offloading) were handled by the sfc driver. If the skb did not fit within the minimum-size of the transmission queue, the network card could repeatedly reset itself. A remote attacker could use this flaw to cause a denial of service. (CVE-2012-3412) Red Hat would like to thank Ben Hutchings of Solarflare (tm) for reporting this issue. This updated package provides updated components that include a fix for one security issue. This issue had no security impact on Red Hat Enterprise Virtualization Hypervisor itself, however. The security fix included in this update addresses the following CVE number : CVE-2012-4423 (libvirt issue) This update also fixes the following bug : * A dependency issue was found between the rhev-hypervisor-tools and rhev-hypervisor6-tools packages. Every time a user with one of the -tools packages installed ran 'yum update', the -tools package they had installed was removed and the other one installed. Even though rhev-hypervisor-tools obsoleted rhev-hypervisor6-tools, this update includes an updated rhev-hypervisor6-tools package that corrects this issue. Note that the package does not have meaningful content, is only here to fix the dependency issue, and may be removed by a future update. (BZ#855391) This update includes the ovirt-node build from RHBA-2012:1374 : https://rhn.redhat.com/errata/RHBA-2012-1374.html Users of the Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which fixes these issues.
