webmin - session ID spoofing

miniserv.pl in the webmin package does not properly handle
metacharacters, such as line feeds and carriage returns, in
Base64-encoded strings used in Basic authentication. This
vulnerability allows remote attackers to spoof a session ID, and
thereby gain root privileges.

For the stable distribution (woody) this problem has been fixed in
version 0.94-7woody1.

The old stable distribution (potato) does not contain a webmin package.

For the unstable distribution (sid) this problem is fixed in version
1.070-1.

We recommend that you update your webmin package.
