Description

Mozilla Firefox is an open source web browser. XULRunner provides the XULRuntime environment for Mozilla Firefox.Several flaws were found in the processing of malformed web content. A webpage containing malicious content could cause Firefox to crash or,potentially, execute arbitrary code with the privileges of the user runningFirefox. (CVE-2010-3169, CVE-2010-2762)Several use-after-free and dangling pointer flaws were found in Firefox. Aweb page containing malicious content could cause Firefox to crash or,potentially, execute arbitrary code with the privileges of the user runningFirefox. (CVE-2010-2760, CVE-2010-2766, CVE-2010-2767, CVE-2010-3167,CVE-2010-3168)Multiple buffer overflow flaws were found in Firefox. A web page containingmalicious content could cause Firefox to crash or, potentially, executearbitrary code with the privileges of the user running Firefox.(CVE-2010-2765, CVE-2010-3166)Multiple cross-site scripting (XSS) flaws were found in Firefox. A web pagecontaining malicious content could cause Firefox to run JavaScript codewith the permissions of a different website. (CVE-2010-2768, CVE-2010-2769)A flaw was found in the Firefox XMLHttpRequest object. A remote site coulduse this flaw to gather information about servers on an internal privatenetwork. (CVE-2010-2764)For technical details regarding these flaws, refer to the Mozilla securityadvisories for Firefox 3.6.9. You can find a link to the Mozilla advisoriesin the References section of this erratum.Note: After installing this update, Firefox will fail to connect (withHTTPS) to a server using the SSL DHE (Diffie-Hellman Ephemeral) keyexchange if the server's ephemeral key is too small. Connecting to suchservers is a security risk as an ephemeral key that is too small makes theSSL connection vulnerable to attack. Refer to the Solution section forfurther information.All Firefox users should upgrade to these updated packages, which containFirefox version 3.6.9, which corrects these issues. After installing theupdate, Firefox must be restarted for the changes to take effect.
