Mozilla Gecko

Mozilla Firefox before 0.10, Mozilla 5.0, and Gecko 20040913 allows remote attackers to cause a denial of service (application crash or memory consumption) via a large binary file with a .html extension.

Mozilla Gecko before 5.0, as used in Firefox before 5.0 and Thunderbird before 5.0, does not block use of a cross-domain image as a WebGL texture, which allows remote attackers to obtain approximate copies of arbitrary images via a timing attack involving a crafted WebGL fragment shader.
