NOTE: Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. Without further investigation we cannot rule out the possibility that for some of these an attacker might be able to prepare memory for exploitation through some means other than JavaScript such as large images.

Multiple unspecified vulnerabilities in Mozilla Firefox 3.x before 3.0.2 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to graphics rendering and (1) handling of a long alert messagebox in the cairo_surface_set_device_offset function, (2) integer overflows when handling animated PNG data in the info_callback function in nsPNGDecoder.cpp, and (3) an integer overflow when handling SVG data in the nsSVGFEGaussianBlurElement::SetupPredivide function in nsSVGFilters.cpp.
