Openwall GNU/*/Linux Information for VU#650937

Concurrent Versions System (CVS) server improperly deallocates memory


Not Affected

Vendor Statement

We don't yet re-distribute CVS in Openwall GNU/*/Linux.

We do, however, provide public anonymous CVS access to a copy of our repository, hosted off a separate machine and in a chroot jail. This kind of vulnerabilities in CVS was expected, and our anoncvs setup is mostly resistant to them: read-only access to the repository is achieved primarily with the use of regular Unix permissions, not controls built into CVS. CVS LockDir option is used to direct CVS lock files to a separate directory tree, actually writable to the pseudo-user. Nevertheless, the anoncvs server has been upgraded to CVS 1.11.5 a few hours after it was released.

Vendor Information

The vendor has not provided us with any further information regarding this vulnerability.
