Discovery 2004-05-02
Entry 2004-05-19

Due to a programming error in code used to parse data received from the client, malformed data can cause a heap buffer to overflow, allowing the client to overwrite arbitrary portions of the server's memory.

A malicious CVS client can exploit this to run arbitrary code on the server at the privilege level of the CVS server software.
