cvs - doubly freed memory

Stefan Esser
discovered a problem in cvs, a concurrent versions
system, which is used for many Free Software projects. The current
version contains a flaw that can be used by a remote attacker to
execute arbitrary code on the CVS server under the user id the CVS
server runs as. Anonymous read-only access is sufficient to exploit
this problem.

For the stable distribution (woody) this problem has been
fixed in version 1.11.1p1debian-8.1.

For the old stable distribution (potato) this problem has been fixed
in version 1.10.7-9.2.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your cvs package immediately.
