For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 3.6.9. You can find a link to the Mozilla advisories
in the References section of this erratum.
Note: After installing this update, Firefox will fail to connect (with
HTTPS) to a server using the SSL DHE (Diffie-Hellman Ephemeral) key
exchange if the server's ephemeral key is too small. Connecting to such
servers is a security risk as an ephemeral key that is too small makes the
SSL connection vulnerable to attack. Refer to the Solution section for
further information.
All Firefox users should upgrade to these updated packages, which contain
Firefox version 3.6.9, which corrects these issues. After installing the
update, Firefox must be restarted for the changes to take effect.
Affected Software/OS:
firefox on CentOS 5
Solution:
Please install the updated packages.
