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"
