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
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
