Title: Sylpheed, Sylpheed-claws: Message reply overflow
Date: March 20, 2005
Bugs: #84056
ID: 200503-26

---

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"
