Synopsis
========

Several format string bugs and buffer overflows were discovered in
metamail, potentially allowing execution of arbitrary code remotely.

Background
==========

Metamail is a program that decodes MIME encoded mail. It is therefore
often automatically called when an email is received or read.

Affected packages
=================

    -------------------------------------------------------------------
     Package            /   Vulnerable   /                  Unaffected
    -------------------------------------------------------------------
  1  net-mail/metamail      < 2.7.45.3                     >= 2.7.45.3

Description
===========

Ulf Harnhammar found two format string bugs and two buffer overflow
bugs in Metamail.

Impact
======

A remote attacker could send a malicious email message and execute
arbitrary code with the rights of the process calling the Metamail
program.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All users of Metamail should upgrade to the latest stable version:

    # emerge sync

    # emerge -pv ">=net-mail/metamail-2.7.45.3"
    # emerge ">=net-mail/metamail-2.7.45.3"
