The nsDocument::MaybePreLoadImage function in content/base/src/nsDocument.cpp in the image-preloading implementation in Mozilla Firefox 3.6 before 3.6.2 does not apply scheme restrictions and policy restrictions to the image's URL, which might allow remote attackers to cause a denial of service (application crash or hang) or hijack the functionality of the browser's add-ons via a crafted SRC attribute of an IMG element, as demonstrated by remote command execution through an ssh: URL in a configuration that supports gnome-vfs with a nonstandard network.gnomevfs.supported-protocols setting.

The browser engine in Mozilla Firefox 3.0.x before 3.0.18, 3.5.x before 3.5.8, and 3.6.x before 3.6.2; Thunderbird before 3.0.2; and SeaMonkey before 2.0.3 allows remote attackers to cause a denial of service (memory corruption and application crash) and possibly execute arbitrary code via vectors related to (1) layout/generic/nsBlockFrame.cpp and (2) the _evaluate function in modules/plugin/base/src/nsNPAPIPlugin.cpp.

The gfxTextRun::SanitizeGlyphRuns function in gfx/thebes/src/gfxFont.c ...

The gfxTextRun::SanitizeGlyphRuns function in gfx/thebes/src/gfxFont.cpp in the browser engine in Mozilla Firefox 3.6 before 3.6.2 on Mac OS X, when the Core Text API is used, does not properly perform certain deletions, which allows remote attackers to cause a denial of service (memory corruption and application crash) and possibly execute arbitrary code via an HTML document containing invisible Unicode characters, as demonstrated by the U+FEFF, U+FFF9, U+FFFA, and U+FFFB characters.

The TraceRecorder::traverseScopeChain function in js/src/jstracer.cpp ...

The TraceRecorder::traverseScopeChain function in js/src/jstracer.cpp in the browser engine in Mozilla Firefox 3.6 before 3.6.2 allows remote attackers to cause a denial of service (memory corruption and application crash) and possibly execute arbitrary code via vectors involving certain indirect calls to the JavaScript eval function.

Use-after-free vulnerability in the imgContainer::InternalAddFrameHelp ...

Use-after-free vulnerability in the imgContainer::InternalAddFrameHelper function in src/imgContainer.cpp in libpr0n in Mozilla Firefox 3.6 before 3.6.2 allows remote attackers to cause a denial of service (heap memory corruption and application crash) or possibly execute arbitrary code via a multipart/x-mixed-replace animation in which the frames have different bits-per-pixel (bpp) values.
