1. Summary:

An updated sylpheed package that fixes a buffer overflow issue is now
available.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

3. Problem description:

Sylpheed is a GTK+ based fast email client.

A buffer overflow bug has been found in the way Sylpheed handles non-ASCII
characters in the header of a message to which a victim replies.  A
carefully crafted email message could potentially allow an attacker to
execute arbitrary code on a victim's machine if they reply to such a
message. The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2005-0667 to this issue.

Users of Sylpheed should upgrade to this updated package, which contains a
backported patch, and is not vulnerable to this issue.
