3. Description:

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 the
CVE-2010-0624 issue.

A denial of service flaw was found in the way tar expanded archive files.
If a user expanded a specially-crafted archive, it could cause the tar
executable to crash. (CVE-2007-4476)

Users of tar are advised to upgrade to this updated package, which contains
backported patches to correct these issues.

4. Solution:

Before applying this update, make sure all previously-released errata
