libtar security update

CentOS Errata and Security Advisory CESA-2013:1418

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.
