Insight
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. For the unstable distribution (sid) this problem has been fixed in version 1.12.5-6. We recommend that you upgrade your cvs package immediately.
