3. Problem description:
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 (cve.mitre.org) has assigned
the name CAN-2005-1111 to this issue.
Additionally, this update adds cpio support for archives larger than 2GB.
However, the size of individual files within an archive is limited to 4GB.
All users of cpio are advised to upgrade to this updated package, which
contains backported fixes for these issues.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied. Use Red Hat
Network to download and update your packages. To launch the Red Hat
Update Agent, use the following command:
