Red Hat 6: RHSA-2013:1418-01 Moderate: libtar Buffer Overflow

red hat
Calendar Grey October 10, 2013
Dist Redhat Esm H88
The libtar package for Red Hat has been revised to address a moderate security vulnerability. It is advisable to upgrade if your systems are impacted.
An updated libtar package that fixes one security issue is now available for Red Hat Enterprise Linux 6

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/site/articles/11258

Summary

The libtar package contains a C library for manipulating tar archives. The library supports both the strict POSIX tar format and many of the commonly used GNU extensions.
Two heap-based buffer overflow flaws were found in the way libtar handled certain archives. If a user were tricked into expanding a specially-crafted archive, it could cause the libtar executable or an application using libtar to crash or, potentially, execute arbitrary code. (CVE-2013-4397)
Note: This issue only affected 32-bit builds of libtar.
Red Hat would like to thank Timo Warns for reporting this issue.
All libtar users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.
