Multiple unspecified vulnerabilities in Mozilla Firefox before 2.0.0.17 and 3.x before 3.0.2, Thunderbird before 2.0.0.17, and SeaMonkey before 1.1.12 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to the JavaScript engine and (1) misinterpretation of the characteristics of Namespace and QName in jsxml.c, (2) misuse of signed integers in the nsEscapeCount function in nsEscape.cpp, and (3) interaction of JavaScript garbage collection with certain use of an NPObject in the nsNPObjWrapper::GetNewOrUsed function in nsJSNPRuntime.cpp.
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 the layout engine and (1) a zero value of the "this" variable in the nsContentList::Item function; (2) interaction of the indic IME extension, a Hindi language selection, and the "g" character; and (3) interaction of the nsFrameList::SortByContentOrder function with a certain insufficient protection of inline frames.
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.
Mozilla Firefox before 2.0.0.17 and 3.x before 3.0.2, Thunderbird before 2.0.0.17, and SeaMonkey before 1.1.12 allow remote attackers to bypass cross-site scripting (XSS) protection mechanisms and conduct XSS attacks via byte order mark (BOM) characters that are removed from JavaScript code before execution, aka "Stripped BOM characters bug."
Mozilla Firefox 2.0.0.14, and other versions before 2.0.0.17, allows remote attackers to bypass cross-site scripting (XSS) protection mechanisms and conduct XSS attacks via HTML-escaped low surrogate characters that are ignored by the HTML parser, as demonstrated by a "jav�ascript" sequence, aka "HTML escaped low surrogates bug."
Directory traversal vulnerability in Mozilla Firefox before 2.0.0.17 and 3.x before 3.0.2, Thunderbird before 2.0.0.17, and SeaMonkey before 1.1.12 on Linux allows remote attackers to read arbitrary files via a .. (dot dot) and URL-encoded / (slash) characters in a resource: URI.
Directory traversal vulnerability in Mozilla Firefox before 2.0.0.17 and 3.x before 3.0.2, Thunderbird before 2.0.0.17, and SeaMonkey before 1.1.12 allows remote attackers to bypass "restrictions imposed on local HTML files," and obtain sensitive information and prompt users to write this information into a file, via directory traversal sequences in a resource: URI.
The XBM decoder in Mozilla Firefox before 2.0.0.17 and SeaMonkey before 1.1.12 allows remote attackers to read uninitialized memory, and possibly obtain sensitive information in opportunistic circumstances, via a crafted XBM image file.
The content layout component in Mozilla Firefox 3.0 and 3.0.1 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted but well-formed web page that contains "a simple set of legitimate HTML tags."
Mozilla Firefox 3 before 3.0.1 on Mac OS X allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted GIF file that triggers a free of an uninitialized pointer.
