Description |
A remote overflow exists in Concurrent Versions System. The CVS fails to handle an empty data line input resulting in a potential single byte overflow. With a specially crafted request, an attacker can cause the execution of the supplied code resulting in a loss of confidentiality, integrity, and/or availability. Since the CVS system is used to version control source code, these flaws put the source code in the repository at risk of being changed. This could lead to future exploits of any software that was checked into the system. These problems were discovered after a system compromise. The subsequent CVS code audit discovered several issues. This should be considered a critical issue and any source code located on public CVS servers should be verified to be correct.
