- A use-after-free issue when viewing XUL documents with scripts disabled could lead to code execution. (CVE-2011-2373)

- A memory corruption issue due to multipart/x-mixed-replace images could lead to memory corruption. (CVE-2011-2377)

- When a JavaScript Array object has its length set to an extremely large value, the iteration of array elements that occurs when its reduceRight method is called could result in code execution due to an invalid index value being used. (CVE-2011-2371)

- It is possible for an image from a different domain to be loaded into a WebGL texture which could be used to steal image data from a different site. (CVE-2011-2366)
