  Use-after-free vulnerability in the nsSVGPathSegList::ReplaceItem
  function in the implementation of SVG element lists allows remote
  attackers to cause a denial of service (application crash) or
  possibly execute arbitrary code via vectors involving a user-supplied
  callback.

CVE-2011-0085

  Use-after-free vulnerability in the nsXULCommandDispatcher function

  callback.

CVE-2011-2364, CVE-2011-2365, CVE-2011-2374, CVE-2011-2376

  arbitrary code via a crafted XUL document.

CVE-2011-2377

  Allow remote attackers to cause a denial of service (memory
  corruption and application crash) or possibly execute arbitrary code
