RHEL 3 : seamonkey (RHSA-2009:1185)

high Nessus Plugin ID 40440

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated SeaMonkey packages that fix a security issue are now available for Red Hat Enterprise Linux 3.

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

SeaMonkey is an open source Web browser, email and newsgroup client, IRC chat client, and HTML editor.

Moxie Marlinspike reported a heap overflow flaw in a regular expression parser in the NSS library (provided by SeaMonkey) used to match common names in certificates. A malicious website could present a carefully-crafted certificate in such a way as to trigger the heap overflow, leading to a crash or, possibly, arbitrary code execution with the permissions of the user running SeaMonkey. (CVE-2009-2404)

Note: in order to exploit this issue without further user interaction, the carefully-crafted certificate would need to be signed by a Certificate Authority trusted by SeaMonkey, otherwise SeaMonkey presents the victim with a warning that the certificate is untrusted.
Only if the user then accepts the certificate will the overflow take place.

All SeaMonkey users should upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the updated packages, SeaMonkey must be restarted for the update to take effect.

Solution

Update the affected packages.
