Debian DSA-505-1 : cvs - heap overflow

high Nessus Plugin ID 15342

Synopsis

The remote Debian host is missing a security-related update.

Description

Stefan Esser discovered a heap overflow in the CVS server, which serves the popular Concurrent Versions System. Malformed 'Entry' Lines in combination with Is-modified and Unchanged can be used to overflow malloc()ed memory. This was proven to be exploitable.

Solution

Upgrade the cvs package immediately.

For the stable distribution (woody) this problem has been fixed in version 1.11.1p1debian-9woody4.
