APP: CVS Excessive Max-dotdot Argument

This signature detects attempts to exploit a vulnerability in Concurrent Versions Systems (CVS). CVS versions 1.11.15 and earlier are vulnerable. Attackers can send excessively large "Max-dotdot" arguments to the CVS server to crash the server, or perform a directory traversal attack against the CVS client.

Extended Description

CVS is prone to multiple vulnerabilities. The issues include a double free vulnerability, format string vulnerabilities, and integer overflows. There is also a null termination issue in the security patch for BID 10384, potentially leading to a server crash. Some of these issues may be leveraged to execute arbitrary code, while other issues may only result in a denial of service.
