Details:

USN-1509-1 fixed vulnerabilities in Firefox. This update provides an updated

Original advisory details:

 Benoit Jacob, Jesse Ruderman, Christian Holler, Bill McCloskey, Brian Smith,
 Gary Kwong, Christoph Diehl, Chris Jones, Brad Lassey, and Kyle Huey discovered
 memory safety issues affecting Firefox. If the user were tricked into opening a
 specially crafted page, an attacker could possibly exploit these to cause a
 denial of service via application crash, or potentially execute code with the
 privileges of the user invoking Firefox. (CVE-2012-1948, CVE-2012-1949)
 
 Mario Gomes discovered that the address bar may be incorrectly updated.
 Drag-and-drop events in the address bar may cause the address of the previous
 site to be displayed while a new page is loaded. An attacker could exploit this
 to conduct phishing attacks. (CVE-2012-1950)
 
 Abhishek Arya discovered four memory safety issues affecting Firefox. If the
 user were tricked into opening a specially crafted page, an attacker could
 possibly exploit these to cause a denial of service via application crash, or
 potentially execute code with the privileges of the user invoking Firefox.
 (CVE-2012-1951, CVE-2012-1952, CVE-2012-1953, CVE-2012-1954)
 
 Mariusz Mlynski discovered that the address bar may be incorrectly updated.
 Calls to history.forward and history.back could be used to navigate to a site
 while the address bar still displayed the previous site. A remote attacker
 could exploit this to conduct phishing attacks. (CVE-2012-1955)
 
 Mario Heiderich discovered that HTML <embed> tags were not filtered out of the
 HTML <description> of RSS feeds. A remote attacker could exploit this to
 conduct cross-site scripting (XSS) attacks via javascript execution in the HTML
 feed view. (CVE-2012-1957)
 
 Arthur Gerkis discovered a use-after-free vulnerability. If the user were
 tricked into opening a specially crafted page, an attacker could possibly
 exploit this to cause a denial of service via application crash, or potentially
 execute code with the privileges of the user invoking Firefox. (CVE-2012-1958)
 
 Bobby Holley discovered that same-compartment security wrappers (SCSW) could be
 bypassed to allow XBL access. If the user were tricked into opening a specially
 crafted page, an attacker could possibly exploit this to execute code with the
 privileges of the user invoking Firefox. (CVE-2012-1959)
 
 Tony Payne discovered an out-of-bounds memory read in Mozilla's color
 management library (QCMS). If the user were tricked into opening a specially
 crafted color profile, an attacker could possibly exploit this to cause a
 denial of service via application crash. (CVE-2012-1960)
 
 Frédéric Buclin discovered that the X-Frame-Options header was ignored when its
 value was specified multiple times. An attacker could exploit this to conduct
 clickjacking attacks. (CVE-2012-1961)
 
 Bill Keese discovered a memory corruption vulnerability. If the user were
 tricked into opening a specially crafted page, an attacker could possibly
 exploit this to cause a denial of service via application crash, or potentially
 execute code with the privileges of the user invoking Firefox. (CVE-2012-1962)
 
 Karthikeyan Bhargavan discovered an information leakage vulnerability in the
 Content Security Policy (CSP) 1.0 implementation. If the user were tricked into
 opening a specially crafted page, an attacker could possibly exploit this to
 access a user's OAuth 2.0 access tokens and OpenID credentials. (CVE-2012-1963)
 
 Matt McCutchen discovered a clickjacking vulnerability in the certificate
 warning page. A remote attacker could trick a user into accepting a malicious
 certificate via a crafted certificate warning page. (CVE-2012-1964)
 
 Mario Gomes and Soroush Dalili discovered that javascript was not filtered out
 of feed URLs. If the user were tricked into opening a specially crafted URL, an
 attacker could possibly exploit this to conduct cross-site scripting (XSS)
 attacks. (CVE-2012-1965)
 
 A vulnerability was discovered in the context menu of data: URLs. If the user
 were tricked into opening a specially crafted URL, an attacker could possibly
 exploit this to conduct cross-site scripting (XSS) attacks. (CVE-2012-1966)
 
 It was discovered that the execution of javascript: URLs was not properly
 handled in some cases. A remote attacker could exploit this to execute code
 with the privileges of the user invoking Firefox. (CVE-2012-1967)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
  ubufox                          2.1.1-0ubuntu0.12.04.1
  xul-ext-ubufox                  2.1.1-0ubuntu0.12.04.1

Ubuntu 11.10:
  ubufox                          2.1.1-0ubuntu0.11.10.1
  xul-ext-ubufox                  2.1.1-0ubuntu0.11.10.1

Ubuntu 11.04:
  ubufox                          2.1.1-0ubuntu0.11.04.1
  xul-ext-ubufox                  2.1.1-0ubuntu0.11.04.1

Ubuntu 10.04 LTS:
  ubufox                          2.1.1-0ubuntu0.10.04.1

When upgrading, users should be aware of the following:

- In Ubuntu 11.04, unity-2d users may lose the ability to view drop-down menus,
context menus, and perform drag-and-drop operations in Firefox. This is a known
issue being tracked in https://launchpad.net/bugs/1020198 and may be fixed in a
later update.

After a standard system update you need to restart Firefox to make
all the necessary changes.
