Addendum

Based on source code analysis, cvs-29 from the Darwin Projects Directory appears to be vulnerable. However, the Apple OS X malloc(3) implementation (phkmalloc) may safely handle the double-free condition. If malloc(3) is configured such that all warnings are fatal ("A" option), the impact of this vulnerability on Darwin cvs-29 may be limited to a denial of service.

Darwin cvs-29 may not be the same cvs code that is shipped with the Apple OS X Developer Tools package.
