Package : cvs
Vulnerability : heap overflow
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2004-0396

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 prooven to be exploitable.

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

We recommend that you upgrade your cvs package immediately.
