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 messages containing attachments with MIME-encoded filenames.

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

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