Package        : util-linux
Vulnerability  : privilege escalation
Problem type   : local
Debian-specific: no
CVE ID         : CAN-2005-2876
Debian Bug     : 328141 329063

David Watson discoverd a bug in mount as provided by util-linux and
other packages such as loop-aes-utils that allows local users to
bypass filesystem access restrictions by re-mounting it read-only.

For the old stable distribution (woody) this problem has been fixed in
version 2.11n-7woody1.

For the stable distribution (sarge) this problem has been fixed in
version 2.12p-4sarge1.

For the unstable distribution (sid) this problem has been fixed in
version 2.12p-8.

We recommend that you upgrade your loop-aes-utils package.
