Description

An updated tar package that fixes two security issues is now available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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.
