RHSA-2011:1244 - Security Advisory

トピック

Updated seamonkey packages that fix one security issue are now available
for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having
important security impact.

説明

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.

解決策

Before applying this update, make sure all previously-released errata
