CESA-2007:1082: firefox security update

Description

Updated firefox packages that fix several security issues are now available for CentOS Linux 4 and 5. 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. A cross-site scripting flaw was found in the way Firefox handled the jar: URI scheme. It was possible for a malicious website to leverage this flaw and conduct a cross-site scripting attack against a user running Firefox. (CVE-2007-5947) Several flaws were found in the way Firefox processed certain malformed web content. A webpage containing malicious content could cause Firefox to crash, or potentially execute arbitrary code as the user running Firefox. (CVE-2007-5959) A race condition existed when Firefox set the "window.location" property for a webpage. This flaw could allow a webpage to set an arbitrary Referer header, which may lead to a Cross-site Request Forgery (CSRF) attack against websites that rely only on the Referer header for protection. (CVE-2007-5960) Users of Firefox are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.
