medium Nessus Plugin ID 14920

Synopsis

The remote Debian host is missing a security-related update.

Description

Using older versions of procmail it was possible to make procmail crash by sending it signals. On systems where procmail is installed setuid this could be exploited to obtain unauthorized privileges.

Upgrade the procmail package immediately.

This problem has been fixed in version 3.20 by the upstream maintainer, included in Debian unstable, and was ported back to version 3.15.2 which is available for the stable Debian GNU/Linux 2.2.
