Debian: DSA 486-1 Urgent: Issues with CVS Remote Access Identified

Two vulnerabilities have been discovered and fixed in CVS:

CAN-2004-0180 - Sebastian Krahmer discovered a vulnerability whereby
a malicious CVS pserver could create arbitary files on the client
system during an update or checkout operation, by supplying absolute
pathnames in RCS diffs.

CAN-2004-0405 - Derek Robert Price discovered a vulnerability whereby
a CVS pserver could be abused by a malicious client to view the
contents of certain files outside of the CVS root directory using
relative pathnames containing "../".

For the current stable distribution (woody) these problems have been
fixed in version 1.11.1p1debian-9woody2.

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you update your cvs package.
