Synopsis
========

Sylpheed and Sylpheed-claws contain a vulnerability that can be
triggered when displaying messages with specially crafted attachments.

Background
==========

Sylpheed is a lightweight email client and newsreader. Sylpheed-claws
is a 'bleeding edge' version of Sylpheed.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 mail-client/sylpheed < 1.0.4 >= 1.0.4
2 mail-client/sylpheed-claws < 1.0.4 >= 1.0.4
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------

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

Sylpheed and Sylpheed-claws fail to properly handle messages containing
attachments with MIME-encoded filenames.

Impact
======

An attacker can send a malicious email message which, when displayed,
would cause the program to crash, potentially allowing the execution of
arbitrary code with the privileges of the user running the software.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Sylpheed users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/sylpheed-1.0.4"

All Sylpheed-claws users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/sylpheed-claws-1.0.4"
