The remote host seems to be running cvstrac, 
a web-based bug and patch-set tracking system for CVS.

This version contains a flaw related to the timeline_page() function
in timeline.c that may allow an attacker to cause a buffer overflow.
An attacker, exploiting this flaw, would be potentially able to
run exploit code on the remote machine.

***** Nessus has determined the vulnerability exists on the target
***** simply by looking at the version number(s) of CVSTrac
***** installed there. 


Solution : Update to version 1.1.4 or disable this CGI suite
Risk factor : High";
