-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: kernel security update Advisory ID: RHSA-2013:0695-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-0695.html Issue date: 2013-04-02 CVE Names: CVE-2013-0871 ===================================================================== 1. Summary: Updated kernel packages that fix one security issue 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. 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 EUS (v. 5.6 server) - i386, ia64, noarch, ppc, s390x, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issue: * A race condition was found in the way the Linux kernel's ptrace implementation handled PTRACE_SETREGS requests when the debuggee was woken due to a SIGKILL signal instead of being stopped. A local, unprivileged user could use this flaw to escalate their privileges. (CVE-2013-0871, Important) Users should 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/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/): 911937 - CVE-2013-0871 kernel: race condition with PTRACE_SETREGS 6.
