1. Summary:

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

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

3. Description:

GNU cpio copies files into or out of a cpio or tar archive.

A heap-based buffer overflow flaw was found in the way cpio expanded
archive files. If a user were tricked into expanding a specially-crafted
archive, it could cause the cpio executable to crash or execute arbitrary
code with the privileges of the user running cpio. (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 cpio expanded archive files.
If a user expanded a specially-crafted archive, it could cause the cpio
executable to crash. (CVE-2007-4476)

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