Package: cvsweb
Vulnerability type: remote shell
Debian-specific: no

The versions of cvsweb distributed in Debian GNU/Linux 2.1 (aka slink) as
well as in the frozen (potato) and unstable (woody) distributions, are
vulnerable to a remote shell exploit. An attacker with write access to the
cvs repository can execute arbitrary code on the server, as the www-data
user.

The vulnerability is fixed in version 109 of cvsweb for the current stable
release (Debian 2.1), in version 1.79-3potato1 for the frozen distribution,
and in version 1.86-1 for the unstable distribution.
