CESA-2007:0979: firefox security update



Updated firefox packages that fix several security bugs 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. Several flaws were found in the way in which Firefox processed certain malformed web content. A web page containing malicious content could cause Firefox to crash or potentially execute arbitrary code as the user running Firefox. (CVE-2007-5338, CVE-2007-5339, CVE-2007-5340) Several flaws were found in the way in which Firefox displayed malformed web content. A web page containing specially-crafted content could potentially trick a user into surrendering sensitive information. (CVE-2007-1095, CVE-2007-3844, CVE-2007-3511, CVE-2007-5334) A flaw was found in the Firefox sftp protocol handler. A malicious web page could access data from a remote sftp site, possibly stealing sensitive user data. (CVE-2007-5337) A request-splitting flaw was found in the way in which Firefox generates a digest authentication request. If a user opened a specially-crafted URL, it was possible to perform cross-site scripting attacks, web cache poisoning, or other, similar exploits. (CVE-2007-2292) All users of Firefox are advised to upgrade to these updated packages, which contain backported patches that correct these issues.
