Severity:	high
Title:	Multiple vulnerabilities in metamail
Date:	05/21/2004
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	Architecture(s)
net-mail/metamail	< 2.7.45.3	>= 2.7.45.3	All supported architectures

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"
