Synopsis

Description

Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox.

A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2012-1948, CVE-2012-1951, CVE-2012-1952, CVE-2012-1953, CVE-2012-1954, CVE-2012-1958, CVE-2012-1962, CVE-2012-1967)

A malicious web page could bypass same-compartment security wrappers (SCSW) and execute arbitrary code with chrome privileges.
(CVE-2012-1959)

A flaw in the context menu functionality in Firefox could allow a malicious website to bypass intended restrictions and allow a cross-site scripting attack. (CVE-2012-1966)

A page different to that in the address bar could be displayed when dragging and dropping to the address bar, possibly making it easier for a malicious site or user to perform a phishing attack.
(CVE-2012-1950)

A flaw in the way Firefox called history.forward and history.back could allow an attacker to conceal a malicious URL, possibly tricking a user into believing they are viewing a trusted site. (CVE-2012-1955)

A flaw in a parser utility class used by Firefox to parse feeds (such as RSS) could allow an attacker to execute arbitrary JavaScript with the privileges of the user running Firefox. This issue could have affected other browser components or add-ons that assume the class returns sanitized input. (CVE-2012-1957)

A flaw in the way Firefox handled X-Frame-Options headers could allow a malicious website to perform a clickjacking attack. (CVE-2012-1961)

A flaw in the way Content Security Policy (CSP) reports were generated by Firefox could allow a malicious web page to steal a victim's OAuth 2.0 access tokens and OpenID credentials. (CVE-2012-1963)

A flaw in the way Firefox handled certificate warnings could allow a man-in-the-middle attacker to create a crafted warning, possibly tricking a user into accepting an arbitrary certificate as trusted.
(CVE-2012-1964)

A flaw in the way Firefox handled feed:javascript URLs could allow output filtering to be bypassed, possibly leading to a cross-site scripting attack. (CVE-2012-1965)

The a previous nss update introduced a mitigation for the CVE-2011-3389 flaw. For compatibility reasons, it remains disabled by default in the nss packages. This update makes Firefox enable the mitigation by default. It can be disabled by setting the NSS_SSL_CBC_RANDOM_IV environment variable to 0 before launching Firefox.

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 10.0.6 ESR.

All Firefox users should upgrade to these updated packages, which contain Firefox version 10.0.6 ESR, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

Solution

Update the affected packages.
