RHEL 4 : firefox (RHSA-2006:0733)

high Nessus Plugin ID 23680

Synopsis

The remote Red Hat host is missing a security update.

Description

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

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

Mozilla Firefox is an open source Web browser.

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

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

A flaw was found in the way Firefox verifies RSA signatures. For RSA keys with exponent 3 it is possible for an attacker to forge a signature that would be incorrectly verified by the NSS library.
Firefox 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 Firefox 1.5.0.7, however Ulrich Kuehn discovered the fix was incomplete (CVE-2006-5462)

Users of Firefox are advised to upgrade to these erratum packages, which contain Firefox version 1.5.0.8 that corrects these issues.

Solution

Update the affected firefox package.
