The JavaScript engine in Mozilla Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) via vectors related to "insufficient class checking" in the Date class.

Integer overflow in xpcom/io/nsEscape.cpp in the browser engine in Mozilla Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) via unknown vectors.

The layout engine in Mozilla Firefox 3.x before 3.0.4, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) via multiple vectors that trigger an assertion failure or other consequences.

Mozilla Firefox 3.x before 3.0.4 assigns chrome privileges to a file: URI when it is accessed in the same tab from a chrome or privileged about: page, which makes it easier for user-assisted attackers to execute arbitrary JavaScript with chrome privileges via malicious code in a file that has already been saved on the local system.

jslock.cpp in Mozilla Firefox 3.x before 3.0.2, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by modifying the window.__proto__.__proto__ object in a way that causes a lock on a non-native object, which triggers an assertion failure related to the OBJ_IS_NATIVE function.

Mozilla Firefox 2.x before 2.0.0.18 and SeaMonkey 1.x before 1.1.13 do not properly check when the Flash module has been dynamically unloaded properly, which allows remote attackers to execute arbitrary code via a crafted SWF file that "dynamically unloads itself from an outside JavaScript function," which triggers an access of an expired memory address.

Mozilla Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 do not properly change the source URI when processing a canvas element and an HTTP redirect, which allows remote attackers to bypass the same origin policy and access arbitrary images that are not directly accessible to the attacker. NOTE: this issue can be leveraged to enumerate software on the client by performing redirections related to moz-icon.

The http-index-format MIME type parser (nsDirIndexParser) in Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 does not check for an allocation failure, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an HTTP index response with a crafted 200 header, which triggers memory corruption and a buffer overflow.

Adobe Flash Player 9.0.124.0 and earlier, when a Mozilla browser is used, does not properly interpret jar: URLs, which allows attackers to obtain sensitive information via unknown vectors.

Multiple cross-site scripting (XSS) vulnerabilities in Mozilla Firefox 3.0.1 through 3.0.3 allow remote attackers to inject arbitrary web script or HTML via an ftp:// URL for an HTML document within a (1) JPG, (2) PDF, or (3) TXT file. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Mozilla Firefox 3.0.1 through 3.0.3, Firefox 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13, when running on Windows, do not properly identify the context of Windows .url shortcut files, which allows user-assisted remote attackers to bypass the Same Origin Policy and obtain sensitive information via an HTML document that is directly accessible through a filesystem, as demonstrated by documents in (1) local folders, (2) Windows share folders, and (3) RAR archives, and as demonstrated by IFRAMEs referencing shortcuts that point to (a) about:cache?device=memory and (b) about:cache?device=disk, a variant of CVE-2008-2810.

The user interface event dispatcher in Mozilla Firefox 3.0.3 on Windows XP SP2 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a series of keypress, click, onkeydown, onkeyup, onmousedown, and onmouseup events. NOTE: it was later reported that Firefox 3.0.2 on Mac OS X 10.5 is also affected.

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.

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.

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.

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&#56325ascript" sequence, aka "HTML escaped low surrogates bug."

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."

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.

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 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.
