Detail
Problem Description: Updated kernel packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - noarch, x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: * Numerous reference count leaks were found in the Linux kernel's block layer I/O context handling implementation. This could allow a local, unprivileged user to cause a denial of service. (CVE-2012-0879, Moderate) * A flaw was found in the Linux kernel's cifs_lookup() implementation. POSIX open during lookup should only be supported for regular files. When non-regular files (for example, a named (FIFO) pipe or other special files) are opened on lookup, it could cause a denial of service. (CVE-2012-1090, Moderate) * It was found that the Linux kernel's register set (regset) common infrastructure implementation did not check if the required get and set handlers were initialized. A local, unprivileged user could use this flaw to cause a denial of service by performing a register set operation with a ptrace() PTRACE_SETREGSET or PTRACE_GETREGSET request. (CVE-2012-1097, Moderate) Red Hat would like to thank H. Peter Anvin for reporting CVE-2012-1097. This update also fixes several bugs and adds various enhancements. 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 these issues, and fix the bugs and add the enhancements noted in the Technical Notes. The system must be rebooted for this update to take effect. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system. 5. Bugs fixed (http://bugzilla.redhat.com/): 789373 - cifs: multiple process stuck waiting for page lock [rhel-6.2.z] 796829 - CVE-2012-0879 kernel: block: CLONE_IO io_context refcounting issues 798293 - CVE-2012-1090 kernel: cifs: dentry refcount leak when opening a FIFO on lookup leads to panic on unmount 799209 - CVE-2012-1097 kernel: regset: Prevent null pointer reference on readonly regsets 802379 - Anomaly in mbind memory map causing Java Hotspot JVM Seg fault with NUMA aware ParallelScavange GC [rhel-6.2.z] |

Title: | DSA-2443-1 linux-2.6 -- privilege escalation/denial of service | ||
Description: | Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2009-4307 Nageswara R Sastry reported an issue in the ext4 filesystem. Local users with the privileges to mount a filesystem can cause a denial of service by providing a s_log_groups_per_flex value greater than 31. CVE-2011-1833 Vasiliy Kulikov of Openwall and Dan Rosenberg discovered an information leak in the eCryptfs filesystem. Local users were able to mount arbitrary directories. CVE-2011-4347 Sasha Levin reported an issue in the device assignment functionality in KVM. Local users with permission to access /dev/kvm could assign unused pci devices to a guest and cause a denial of service. CVE-2012-0045 Stephan Barwolf reported an issue in KVM. Local users in a 32-bit guest running on a 64-bit system can crash the guest with a syscall instruction. CVE-2012-1090 CAI Qian reported an issue in the CIFS filesystem. A reference count leak can occur during the lookup of special files, resulting in a denial of service on umount. CVE-2012-1097 H. Peter Anvin reported an issue in the regset infrastructure. Local users can cause a denial of service by triggering the write methods of readonly regsets. | ||
