CVS exploit leads to project server compromise
Users of Concurrent Versions System (CVS) software are being urged to patch their systems against an exploit used to hack the project's web site.

The vulnerability in CVS, which allows a buffer overflow, was discovered May 2 by Stefan Esser of e-matters and made public, along with a patch, on May 19.
