Synopsis
========

Balsa is vulnerable to a buffer overflow allowing for the user-assisted
execution of arbitrary code.

Background
==========

Balsa is a highly configurable email client for GNOME.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 mail-client/balsa < 2.3.20 >= 2.3.20

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

Evil Ninja Squirrel discovered a stack-based buffer overflow in the
ir_fetch_seq() function when receiving a long response to a FETCH
command (CVE-2007-5007).

Impact
======

A remote attacker could entice a user to connect to a malicious or
compromised IMAP server, possibly leading to the execution of arbitrary
code with the rights of the user running Balsa.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Balsa users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/balsa-2.3.20"
