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, Red Hat Enterprise Linux 3, and Red Hat
Enterprise Linux 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-2008-5500, CVE-2008-5501, CVE-2008-5502, CVE-2008-5504, CVE-2008-5511,
CVE-2008-5512, CVE-2008-5513)

Several flaws were 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-2008-5503,
CVE-2008-5506, CVE-2008-5507)

A flaw was found in the way malformed URLs were processed by SeaMonkey.
This flaw could prevent various URL sanitization mechanisms from properly
parsing a malicious URL. (CVE-2008-5508)

Note: after the errata packages are installed, SeaMonkey must be restarted
for the update to take effect.

All SeaMonkey users should upgrade to these updated packages, which contain
backported patches to resolve these issues.
