Vulnerability Assessment Details

RHSA-2006-0734: seamonkey

Vulnerability Assessment Summary
Check for the version of the seamonkey packages

Detailed Explanation for this Vulnerability Assessment


Updated seamonkey packages that fix several security bugs 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.

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

Several flaws were found in the way SeaMonkey processes certain malformed
Javascript code. A malicious web page could cause the execution of
Javascript code in such a way that could cause SeaMonkey to crash or
execute arbitrary code as the user running SeaMonkey. (CVE-2006-5463,
CVE-2006-5747, CVE-2006-5748)

Several flaws were found in the way SeaMonkey renders web pages. A
malicious web page could cause the browser to crash or possibly execute
arbitrary code as the user running SeaMonkey. (CVE-2006-5464)

A flaw was found in the way SeaMonkey verifies RSA signatures. For RSA keys
with exponent 3 it is possible for a possible hacker to forge a signature that
would be incorrectly verified by the NSS library. SeaMonkey as shipped
trusts several root Certificate Authorities that use exponent 3. An
attacker could have created a carefully crafted SSL certificate which be
incorrectly trusted when their site was visited by a victim. This flaw was
previously thought to be fixed in SeaMonkey 1.0.5, however Ulrich Kuehn
discovered the fix was incomplete (CVE-2006-5462)

Users of SeaMonkey are advised to upgrade to these erratum packages, which
contains SeaMonkey version 1.0.6 that corrects these issues.
