Sylpheed, Sylpheed-claws: Message reply overflow — GLSA 200503-26

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

Affected Packages

mail-client/sylpheed on all architectures
Affected versions < 1.0.3
Unaffected versions >= 1.0.3
mail-client/sylpheed-claws on all architectures
Affected versions < 1.0.3
Unaffected versions >= 1.0.3

Background

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

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:
