Synopsis
=======

Sylpheed and Sylpheed-claws contain a vulnerability that can be triggered when replying to specially crafted messages.



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 < 1.0.3 >= 1.0.3
2 mail-client/sylpheed-claws < 1.0.3 >= 1.0.3
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------

Description
==========

Sylpheed and Sylpheed-claws fail to properly handle non-ASCII characters in email headers when composing reply messages.

Impact
=====

An attacker can send an email containing a malicious non-ASCII header which, when replied to, 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-1.0.3"

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

# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/sylpheed-claws-1.0.3"
