Description:
A vulnerability was reported in Sylpheed. A remote user may be able to execute arbitrary code on the target system in certain cases.
A remote user can send a message with specially crafted headers to the target user. Then, when the target user replies to the affected message, a buffer overflow may occur. It may be possible to execute arbitrary code, however, the report did not confirm this.
Certain headers containing non-ASCII characters can trigger the overflow.

Impact:
A remote user may be able to execute arbitrary code on the target user's system.
[Editor's note: The report did not confirm code execution.]

Solution:
Red Hat has released a fix.

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.
