CESA-2007:1084: seamonkey security update

Description

Updated seamonkey packages that fix several security issues are now available for CentOS 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. A cross-site scripting flaw was found in the way SeaMonkey 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 SeaMonkey. (CVE-2007-5947) Several flaws were found in the way SeaMonkey processed certain malformed web content. A webpage containing malicious content could cause SeaMonkey to crash, or potentially execute arbitrary code as the user running SeaMonkey. (CVE-2007-5959) A race condition existed when Seamonkey 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 SeaMonkey are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.
