Detail
Problem Description: Updated kernel packages that fix one security issue are now available for Red Hat Enterprise Linux 6.2 Advanced 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux AUS (v. 6.2 server) - noarch, x86_64 Red Hat Enterprise Linux Server Optional AUS (v. 6.2) - x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. * It was found that the Linux kernel's ptrace subsystem allowed a traced process' instruction pointer to be set to a non-canonical memory address without forcing the non-sysret code path when returning to user space. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-4699, Important) Note: The CVE-2014-4699 issue only affected systems using an Intel CPU. Red Hat would like to thank Andy Lutomirski for reporting this issue. All kernel users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. 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/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 (https://bugzilla.redhat.com/): 1115927 - CVE-2014-4699 kernel: x86_64: ptrace: sysret to non-canonical address |
