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"
