RHSA-2009:1096 - Security Advisory

Topic

Updated seamonkey packages that fix several security issues are now
available for Red Hat Enterprise Linux 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-2009-1392, CVE-2009-1833, CVE-2009-1838, CVE-2009-1841)

A flaw was found in the processing of malformed, local file content. If a
user loaded malicious, local content via the file:// URL, it was possible
for that content to access other local data. (CVE-2009-1835)

All SeaMonkey users should upgrade to these updated packages, which correct
these issues. After installing the update, SeaMonkey must be restarted for
the changes to take effect.
