(RHSA-2005:806) cpio security update

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

A race condition bug was found in cpio. It is possible for a local
malicious user to modify the permissions of a local file if they have write
access to a directory in which a cpio archive is being extracted. The
Common Vulnerabilities and Exposures project has assigned the name
CVE-2005-1111 to this issue.

It was discovered that cpio uses a 0 umask when creating files using the -O
(archive) option. This creates output files with mode 0666 (all users can
read and write) regardless of the user’s umask setting. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CVE-1999-1572 to this issue.

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