Solution
Please Install the Updated Packages.
Insight
SeaMonkey is an open source web browser, email and newsgroup client, IRC chat client, and HTML editor.
It was found that a Certificate Authority (CA) issued a fraudulent HTTPS certificate. This update renders any HTTPS certificates signed by that CA as untrusted, except for a select few. The now untrusted certificates that were issued before July 1, 2011 can be manually re-enabled and used again at your own risk in SeaMonkey
however, affected certificates issued
after this date cannot be re-enabled or used. (BZ#734316)
All SeaMonkey users should upgrade to these updated packages, which correct this issue. After installing the update, SeaMonkey must be restarted for the changes to take effect.
Affected
seamonkey on CentOS 4
