Original advisory details:

 Multiple memory vulnerabilities were discovered in the browser rendering
 engine. An attacker could use these to possibly execute arbitrary code with
 the privileges of the user invoking Firefox. (CVE-2011-2364, CVE-2011-2365,
 CVE-2011-2374, CVE-2011-2376)

 Martin Barbella discovered that under certain conditions, viewing a XUL
 document while JavaScript was disabled caused deleted memory to be
 accessed. An attacker could potentially use this to crash Firefox or
 execute arbitrary code with the privileges of the user invoking Firefox.
 (CVE-2011-2373)

 Jordi Chancel discovered a vulnerability on multipart/x-mixed-replace
 images due to memory corruption. An attacker could potentially use this to
 crash Firefox or execute arbitrary code with the privileges of the user
 invoking Firefox. (CVE-2011-2377)

 Chris Rohlf and Yan Ivnitskiy discovered an integer overflow vulnerability
 in JavaScript Arrays. An attacker could potentially use this to execute
 arbitrary code with the privileges of the user invoking Firefox.
 (CVE-2011-2371)

 Multiple use-after-free vulnerabilities were discovered. An attacker could
 potentially use these to execute arbitrary code with the privileges of the
 user invoking Firefox. (CVE-2011-0083, CVE-2011-0085, CVE-2011-2363)

 David Chan discovered that cookies did not honor same-origin conventions.
 This could potentially lead to cookie data being leaked to a third party.
 (CVE-2011-2362)");
