RHEL 3 : seamonkey (RHSA-2009:1432)

This script is Copyright (C) 2009-2017 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated SeaMonkey packages that fix several security issues are now
available for Red Hat Enterprise Linux 3.

This update has been rated as having critical security impact by the
Red Hat Security Response Team.

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 with the privileges of the
user running SeaMonkey. (CVE-2009-3072, CVE-2009-3075)

A use-after-free flaw was found in SeaMonkey. An attacker could use
this flaw to crash SeaMonkey or, potentially, execute arbitrary code
with the privileges of the user running SeaMonkey. (CVE-2009-3077)

Dan Kaminsky discovered flaws in the way browsers such as SeaMonkey
handle NULL characters in a certificate. If an attacker is able to get
a carefully-crafted certificate signed by a Certificate Authority
trusted by SeaMonkey, the attacker could use the certificate during a
man-in-the-middle attack and potentially confuse SeaMonkey into
accepting it by mistake. (CVE-2009-2408)

Descriptions in the dialogs when adding and removing PKCS #11 modules
were not informative. An attacker able to trick a user into installing
a malicious PKCS #11 module could use this flaw to install their own
Certificate Authority certificates on a user's machine, making it
possible to trick the user into believing they are viewing a trusted
site or, potentially, execute arbitrary code with the privileges of
the user running SeaMonkey. (CVE-2009-3076)

A flaw was found in the way SeaMonkey displays the address bar when
window.open() is called in a certain way. An attacker could use this
flaw to conceal a malicious URL, possibly tricking a user into
believing they are viewing a trusted site. (CVE-2009-2654)

Dan Kaminsky found that browsers still accept certificates with MD2
hash signatures, even though MD2 is no longer considered a
cryptographically strong algorithm. This could make it easier for an
attacker to create a malicious certificate that would be treated as
trusted by a browser. NSS (provided by SeaMonkey) now disables the use
of MD2 and MD4 algorithms inside signatures by default.

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.
