Severity: High
Title: Multiple vulnerabilities in metamail
Date: May 21, 2004
Bugs: #42133
ID: 200405-17

---

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"
