Sylpheed < 1.0.3 Invalid Header Overflow

High

Synopsis

The remote host is vulnerable to a buffer overflow.

Description

The remote client is running Sylpheed, an email client for Unix and Unix-like operating systems. This version is vulnerable to a buffer overflow via invalid headers. Specifically, if a specially crafted email message is replied to, a buffer overflow may occur on the local machine. To exploit this, an attacker would need to be able to craft an email and entice a local user to both read and reply to the email. Successful exploitation would result in the attacker executing arbitrary code on the remote client.

Solution

Upgrade to version 1.0.3 or higher.
