"An updated cpio package that fixes multiple issues is now available.

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

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."
