Original advisory details:

 Gary Kwong, Christian Holler, Jesse Ruderman, Steve Fink, Bob Clary, Andrew
 Sutherland, Jason Smith, John Schoenick, Vladimir Vukicevic and Daniel
 Holbert discovered memory safety issues affecting Firefox. If the user were
 tricked into opening a specially crafted page, an attacker could exploit
 these to cause a denial of service via application crash, or potentially
 execute code with the privileges of the user invoking Firefox.
 (CVE-2012-1970, CVE-2012-1971)

 Abhishek Arya discovered multiple use-after-free vulnerabilities. If the
 user were tricked into opening a specially crafted page, an attacker could
 exploit these to cause a denial of service via application crash, or
 potentially execute code with the privileges of the user invoking Firefox.
 (CVE-2012-1972, CVE-2012-1973, CVE-2012-1974, CVE-2012-1975, CVE-2012-1976,
 CVE-2012-3956, CVE-2012-3957, CVE-2012-3958, CVE-2012-3959, CVE-2012-3960,
 CVE-2012-3961, CVE-2012-3962, CVE-2012-3963, CVE-2012-3964)

 Mariusz Mlynsk discovered that it is possible to shadow the location object
 using Object.defineProperty. This could potentially result in a cross-site
 scripting (XSS) attack against plugins. With cross-site scripting
 vulnerabilities, if a user were tricked into viewing a specially crafted
 page, a remote attacker could exploit this to modify the contents or steal
 confidential data within the same domain. (CVE-2012-1956)

 Mariusz Mlynski discovered an escalation of privilege vulnerability through
 about:newtab. This could possibly lead to potentially code execution with
 the privileges of the user invoking Firefox. (CVE-2012-3965)

 Frederic Hoguin discovered that bitmap format images with a negative height
 could potentially result in memory corruption. If the user were tricked
 into opening a specially crafted image, an attacker could exploit
 this to cause a denial of service via application crash, or potentially
 execute code with the privileges of the user invoking Firefox.
 (CVE-2012-3966)

 It was discovered that Firefox's WebGL implementation was vulnerable to
 multiple memory safety issues. If the user were tricked into opening a
 specially crafted page, an attacker could exploit these to cause a denial
 of service via application crash, or potentially execute code with the
 privileges of the user invoking Firefox. (CVE-2012-3967, CVE-2012-3968)

 Arthur Gerkis discovered multiple memory safety issues in Firefox's
 Scalable Vector Graphics (SVG) implementation. If the user were tricked
 into opening a specially crafted image, an attacker could exploit these to
 cause a denial of service via application crash, or potentially execute
 code with the privileges of the user invoking ... [Please see the references for more information on the vulnerabilities]");
