Oracle alert ELSA-2012-0350 (kernel)
Oracle Linux Security Advisory ELSA-2012-0350 https://rhn.redhat.com/errata/RHSA-2012-0350.html The following updated rpms for Oracle Linux 6 have been uploaded to the Unbreakable Linux Network: i386: kernel-2.6.32-220.7.1.el6.i686.rpm kernel-debug-2.6.32-220.7.1.el6.i686.rpm kernel-debug-devel-2.6.32-220.7.1.el6.i686.rpm kernel-devel-2.6.32-220.7.1.el6.i686.rpm kernel-doc-2.6.32-220.7.1.el6.noarch.rpm kernel-firmware-2.6.32-220.7.1.el6.noarch.rpm kernel-headers-2.6.32-220.7.1.el6.i686.rpm perf-2.6.32-220.7.1.el6.i686.rpm python-perf-2.6.32-220.7.1.el6.i686.rpm x86_64: kernel-2.6.32-220.7.1.el6.x86_64.rpm kernel-debug-2.6.32-220.7.1.el6.x86_64.rpm kernel-debug-devel-2.6.32-220.7.1.el6.x86_64.rpm kernel-devel-2.6.32-220.7.1.el6.x86_64.rpm kernel-doc-2.6.32-220.7.1.el6.noarch.rpm kernel-firmware-2.6.32-220.7.1.el6.noarch.rpm kernel-headers-2.6.32-220.7.1.el6.x86_64.rpm perf-2.6.32-220.7.1.el6.x86_64.rpm python-perf-2.6.32-220.7.1.el6.x86_64.rpm SRPMS: http://oss.oracle.com/ol6/SRPMS-updates/kernel-2.6.32-220... Users with Oracle Linux Premier Support can now use Ksplice to patch against this Security Advisory. We recommend that all users of Oracle Linux 6 install these updates. Users of Ksplice Uptrack can install these updates by running : # /usr/sbin/uptrack-upgrade -y On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf, these updates will be installed automatically and you do not need to take any additional action. Description of changes: * CVE-2011-4077: Buffer overflow in xfs_readlink. A flaw in the way the XFS filesystem implementation handled links with pathnames larger than MAXPATHLEN allowed an attacker to mount a malicious XFS image that could crash the system or result in privilege escalation. * CVE-2011-4081: NULL pointer dereference in GHASH cryptographic algorithm. Nick Bowler reported an issue in the GHASH message digest algorithm. ghash_update can pass a NULL pointer to gf128mul_4k_lle in some cases, leading to a NULL pointer dereference (kernel OOPS). * CVE-2011-4132: Denial of service in Journaling Block Device layer. A flaw in the way the Journaling Block Device (JBD) layer handled an invalid log first block value allowed an attacker to mount a malicious ext3 or ext4 image that would crash the system. * CVE-2011-4347: Denial of service in KVM device assignment. Several bugs that allowed unprivileged users to improperly assign devices to KVM guests could result in a denial of service. * CVE-2011-4622: NULL pointer deference in KVM interval timer emulation. Starting PIT timers in the absence of irqchip support could cause a NULL pointer dereference and kernel OOPs. * CVE-2012-0038: In-memory corruption in XFS ACL processing. A missing check in xfs_acl_from_disk on the number of XFS ACLs could result in in-memory corruption and a kernel panic. * CVE-2012-0045: Denial of service in KVM system call emulation. A bug in the system call emulation for allowed local users on a 32-bit KVM guest system to cause the guest system to panic. * CVE-2012-0207: Denial of service bug in IGMP. The IGMP subsystem's compatibility handling of v2 packets had a bug in the computation of a delay field which could result in division by zero (causing a kernel panic). * CVE-2011-4594: Denial of service in network message batching. Two flaws were found in the way the Linux kernel's __sys_sendmsg() function, when invoked via the sendmmsg() system call, accessed user-space memory. A local, unprivileged user could use these flaws to cause a denial of service.
