Synopsis
Critical: seamonkey security update
Type/Severity
Security Advisory: Critical
Topic
Updated seamonkey packages that fix security issues are now available for
Red Hat Enterprise Linux 2.1, 3, and 4.
This update has been rated as having critical security impact by the Red
Hat Security Response Team.
Description
SeaMonkey is an open source Web browser, email and newsgroup client, IRC
chat client, and HTML editor.
Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause SeaMonkey to crash or,
potentially, execute arbitrary code as the user running SeaMonkey.
(CVE-2009-0040, CVE-2009-0772, CVE-2009-0774, CVE-2009-0775)
A flaw was found in the way malformed content was processed. A website
containing specially-crafted content could, potentially, trick a SeaMonkey
user into surrendering sensitive information. (CVE-2009-0776)
All SeaMonkey users should upgrade to these updated packages, which contain
backported patches that correct these issues. After installing the update,
SeaMonkey must be restarted for the changes to take effect.
