RHEL 4 : firefox (RHSA-2006:0733)
High Nessus Plugin ID 23680
SynopsisThe remote Red Hat host is missing a security update.
DescriptionUpdated 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.
(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 126.96.36.199, 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 188.8.131.52 that corrects these issues.
SolutionUpdate the affected firefox package.
