1. Summary:

An updated cpio package that fixes a security issue and various bugs is now
available.

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

3. Problem description:

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

A buffer overflow was found in cpio on 64-bit platforms. By tricking a
user into adding a specially crafted large file to a cpio archive, a local
attacker may be able to exploit this flaw to execute arbitrary code with
the target user's privileges. (CVE-2005-4268)

This erratum also addresses the following bugs:

* cpio did not set exit codes appropriately.

* cpio did not create a ram disk properly.

All users of cpio are advised to upgrade to this updated package, which
contains backported fixes to correct these issues.
