An audit of the cvs codebase performed by Stefan Esser and Sebastian Krahmer 
has found some potential remote vulnerabilities in cvs.

While no exploits are known to exist for these bugs under OpenBSD at this time, 
some of the bugs have proven exploitable on other operating systems.  Therefore, 
we encourage users running cvs servers to patch their systems.  Users running 
cvs clients (but not servers) do not need to update.

The fixes have been committed to OpenBSD-current as well as the 3.4 and 3.5 -stable branches.

Patches against OpenBSD 3.4 and 3.5 are also available:
