3. Problem description:

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

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 can read and write) regardless of the user's umask setting. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-1999-1572 to this issue.

All users of cpio should upgrade to this updated package, which resolves this issue, and adds support for large files (> 2GB).
