Package: nmh
Vulnerability type: remote exploit
Debian-specific: no

The version of nmh that was distributed in Debian GNU/Linux 2.1 (aka slink)
did not check incoming mail messages properly. This could be exploited by
using carefully designed MIME headers to trick mhshow into executing
arbitrary shell code.

This has been fixed in version 0.27-0.28-pre8-4. We recommend you upgrade
your nmh package immediately.
