Package : cpio
Vulnerability : broken file permissions
Problem-Type : local
Debian-specific: no
CVE ID : CAN-1999-1572

It has been discovered, that cpio, a program to manage archives of files, creates output files with -O and -F with broken permissions due to a reset zero umask which allows local users to read or overwrite those files.

For the stable distribution (woody) this problem has been fixed in version 2.4.2-39woody1

We recommend that you upgrade your cpio package.
