The vulnerability is caused due to an array-indexing error in the "apply_rcs_change()" function in ccvs/src/rcs.c while processing delta fragment changes from a file in RCS (Revision Control System) format. This can be exploited to cause a heap-based buffer overflow by tricking a user to checkout a specially crafted file. The vulnerability is reported in version 1.11.23. Other versions may also be affected. SOLUTION: Fixed in the CVS repository.
