  - Errors in the WebGL implementation can allow the     loading of WebGL textures from cross-domain images or     allow the crash of the application and execution of     arbitrary code. (CVE-2011-2366, CVE-2011-2368)

  - An out-of-bounds read error exists in the WebGL     implementation that can lead to crashes and may allow     an attacker to read arbitrary data from the GPU,     including that of other processes. (CVE-2011-2367)

  - An error exists in the decoding of HTML-encoded     entities contained in SVG elements. This error could lead     to cross-site scripting attacks. (CVE-2011-2369)

  - An unspecified error exists that allows non-whitelisted     sites to trigger an install dialog for add-ons and     themes. (CVE-2011-2370)

  - 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)

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

  - Multiple memory safety issues can lead to application     crashes and possibly remote code execution.
    (CVE-2011-2375)

  - A memory corruption issue due to multipart /     x-mixed-replace images could lead to memory corruption.
