Synopsis
========

A vulnerability in SquirrelMail might allow remote attackers to execute
arbitrary code.

Background
==========

SquirrelMail is a webmail package written in PHP. It supports IMAP and
SMTP and can optionally be installed with SQL support.

Affected packages

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 mail-client/squirrelmail
< 1.4.23_pre20140426 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.

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

It was discovered that the sendmail.cf file is mishandled in a popen
call.

Impact
======

A remote attacker, by enticing a user to open an e-mail attachment,
could execute arbitrary shell commands.

Workaround

There is no known workaround at this time.

Resolution
==========

Gentoo has discontinued support for SquirrelMail and recommends that
users unmerge the package:

# emerge --unmerge "mail-client/squirrelmail"
