Double-free vulnerability in CVS 1.11.4 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via a malformed Directory request, as demonstrated by bypassing write checks to execute Update-prog and Checkin-prog commands.
The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
