===================================================================== Red Hat Security Advisory
Synopsis: Moderate: libtirpc security update Advisory ID: RHSA-2013:0884-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-0884.html Issue date: 2013-05-30 CVE Names: CVE-2013-1950 =====================================================================
1. Summary:
Updated libtirpc packages that fix one security issue are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate 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 Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, 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, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64
3. Description:
These packages provide a transport-independent RPC (remote procedure call) implementation.
A flaw was found in the way libtirpc decoded RPC requests. A specially-crafted RPC request could cause libtirpc to attempt to free a buffer provided by an application using the library, even when the buffer was not dynamically allocated. This could cause an application using libtirpc, such as rpcbind, to crash. (CVE-2013-1950)
Red Hat would like to thank Michael Armstrong for reporting this issue.
Users of libtirpc should upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications using libtirpc must be restarted for the 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
5. Bugs fixed (http://bugzilla.redhat.com/):
