Debian CVS Password Protection Bypass and Denial of Service

   
LinuxDebian has issued an update for cvs. This fixes two vulnerabilities, which can be exploited by malicious people to bypass password protection or cause a DoS (Denial of Service).

1) A security issue makes it possible to bypass the password protection and gain access to a repository when using the pserver access method.

2) A vulnerability can be exploited to crash the CVS server when the cvs-repouids file exists but doesn't contain a mapping for the current repository.

OPERATING SYSTEM:
Debian GNU/Linux unstable alias sid
Debian GNU/Linux 3.0

SOLUTION:
Apply updated packages.

-- Debian GNU/Linux 3.0 alias woody --
