tar security update

CentOS Errata and Security Advisory CESA-2010:0142

The GNU tar program saves many files together in one archive and can
restore individual files (or all of the files) from that archive.

A heap-based buffer overflow flaw was found in the way tar expanded archive
files. If a user were tricked into expanding a specially-crafted archive,
it could cause the tar executable to crash or execute arbitrary code with
the privileges of the user running tar. (CVE-2010-0624)

Red Hat would like to thank Jakob Lell for responsibly reporting this
issue.

Users of tar are advised to upgrade to this updated package, which contains
a backported patch to correct this issue.
