1. Summary:

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

The Red Hat Security Response Team has rated this update as having critical
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Description:

SeaMonkey is an open source web browser, email and newsgroup client, IRC
chat client, and HTML editor.

A flaw was found in the way SeaMonkey handled malformed JPEG images. A
website containing a malicious JPEG image could cause SeaMonkey to crash
or, potentially, execute arbitrary code with the privileges of the user
running SeaMonkey. (CVE-2011-2377)

Multiple dangling pointer flaws were found in SeaMonkey. A web page
containing malicious content could cause SeaMonkey to crash or,
potentially, execute arbitrary code with the privileges of the user running
SeaMonkey. (CVE-2011-0083, CVE-2011-0085, CVE-2011-2363)

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 with the privileges of the user running
SeaMonkey. (CVE-2011-2364, CVE-2011-2365, CVE-2011-2374, CVE-2011-2375,
CVE-2011-2376)

An integer overflow flaw was found in the way SeaMonkey handled JavaScript
Array objects. A website containing malicious JavaScript could cause
SeaMonkey to execute that JavaScript with the privileges of the user
running SeaMonkey. (CVE-2011-2371)

A use-after-free flaw was found in the way SeaMonkey handled malformed
JavaScript. A website containing malicious JavaScript could cause SeaMonkey
to execute that JavaScript with the privileges of the user running
SeaMonkey. (CVE-2011-2373)

It was found that SeaMonkey could treat two separate cookies as
interchangeable if both were for the same domain name but one of those
domain names had a trailing "." character. This violates the same-origin
policy and could possibly lead to data being leaked to the wrong domain.
(CVE-2011-2362)

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.
