Mozilla Firefox before 3.0.16 and 3.5.x before 3.5.6, and SeaMonkey before 2.0.1, allows remote attackers to associate spoofed content with an invalid URL by setting document.location to this URL, and then writing arbitrary web script or HTML to the associated blank document, a related issue to CVE-2009-2654.

Unspecified vulnerability in the browser engine in Mozilla Firefox before 3.0.16, SeaMonkey before 2.0.1, and Thunderbird allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The GeckoActiveXObject function in Mozilla Firefox before 3.0.16 and 3.5.x before 3.5.6, and SeaMonkey before 2.0.1, generates different exception messages depending on whether the referenced COM object is listed in the registry, which allows remote attackers to obtain potentially sensitive information about installed software by making multiple calls that specify the ProgID values of different COM objects.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.0.16 and 3.5.x before 3.5.6, SeaMonkey before 2.0.1, and Thunderbird allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The nsGIFDecoder2::GifWrite function in decoders/gif/nsGIFDecoder2.cpp in libpr0n in Mozilla Firefox before 3.5.5 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an animated GIF file with a large image size, a different vulnerability than CVE-2009-3373.

Mozilla Firefox 3.0.1 and earlier allows remote attackers to cause a denial of service (browser hang) by calling the window.print function in a loop, aka a "printing DoS attack," possibly a related issue to CVE-2009-0821.

Unspecified vulnerability in the JavaScript engine in Mozilla Firefox before 3.0.14 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Mozilla Firefox before 3.0.14 does not properly implement certain dialogs associated with the (1) pkcs11.addmodule and (2) pkcs11.deletemodule operations, which makes it easier for remote attackers to trick a user into installing or removing an arbitrary PKCS11 module.

Mozilla Firefox before 3.0.14, and 3.5.x before 3.5.3, does not properly manage pointers for the columns (aka TreeColumns) of a XUL tree element, which allows remote attackers to execute arbitrary code via a crafted HTML document, related to a "dangling pointer vulnerability."

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.0.14 and 3.5.x before 3.5.3, Thunderbird before 2.0.0.24, and SeaMonkey before 1.1.19 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to the BinHex decoder in netwerk/streamconv/converters/nsBinHexDecoder.cpp, and unknown vectors.
