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

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your cpio package.
