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."

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.

Multiple unspecified vulnerabilities in the JavaScript engine in Mozilla Firefox before 3.0.14 and 3.5.x before 3.5.2, 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 use of mutable strings in the js_StringReplaceHelper function in js/src/jsstr.cpp, and unknown vectors.

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.

Unspecified vulnerability in the JavaScript engine in Mozilla Firefox 3.5.x before 3.5.3 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

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.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.0.14, and 3.5.x before 3.5.2, allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.0.14 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Unspecified vulnerability in the browser engine in Mozilla Firefox 3.5.x before 3.5.3 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Mozilla Firefox 3.0.13 and earlier, 3.5, 3.6 a1 pre, and 3.7 a1 pre; SeaMonkey 1.1.17; and Mozilla 1.7.x and earlier do not properly handle javascript: URIs in HTML links within 302 error documents sent from web servers, which allows user-assisted remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Location HTTP response header or (2) specifying the content of a Location HTTP response header.

Mozilla Firefox 3.0.13 and earlier, 3.5, 3.6 a1 pre, and 3.7 a1 pre does not properly block data: URIs in Location headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Location header that contains JavaScript sequences in a data:text/html URI or (2) entering a data:text/html URI with JavaScript sequences when specifying the content of a Location header. NOTE: the JavaScript executes outside of the context of the HTTP site.

Mozilla Firefox 3.0.13 and earlier, 3.5, 3.6 a1 pre, and 3.7 a1 pre; SeaMonkey 1.1.17; and Mozilla 1.7.x and earlier do not properly block data: URIs in Refresh headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Refresh header that contains JavaScript sequences in a data:text/html URI or (2) entering a data:text/html URI with JavaScript sequences when specifying the content of a Refresh header. NOTE: in some product versions, the JavaScript executes outside of the context of the HTTP site.

Mozilla Firefox 3.5.1 and SeaMonkey 1.1.17, and Flock 2.5.1, allow context-dependent attackers to spoof the address bar, via window.open with a relative URI, to show an arbitrary file: URL after a victim has visited any file: URL, as demonstrated by a visit to a file: document written by the attacker.

Mozilla Firefox 3.5.2 on Windows XP, in some situations possibly involving an incompletely configured protocol handler, does not properly implement setting the document.location property to a value specifying a protocol associated with an external application, which allows remote attackers to cause a denial of service (memory consumption) via vectors involving a series of function calls that set this property, as demonstrated by (1) the chromehtml: protocol and (2) the aim: protocol.

Mozilla Firefox 3.0.6 through 3.0.13, and 3.5.x, allows remote attackers to cause a denial of service (CPU consumption) via JavaScript code with a long string value for the hash property (aka location.hash), a related issue to CVE-2008-5715.

The nsDocument::SetScriptGlobalObject function in content/base/src/nsDocument.cpp in Mozilla Firefox 3.5.x before 3.5.2, when certain add-ons are enabled, does not properly handle a Link HTTP header, which allows remote attackers to execute arbitrary JavaScript with chrome privileges via a crafted web page, related to an incorrect security wrapper.

The js_watch_set function in js/src/jsdbgapi.cpp in the JavaScript engine in Mozilla Firefox before 3.0.12 allows remote attackers to cause a denial of service (assertion failure and application exit) or possibly execute arbitrary code via a crafted .js file, related to a "memory safety bug." NOTE: this was originally reported as affecting versions before 3.0.13.

libvorbis before r16182, as used in Mozilla Firefox 3.5.x before 3.5.2 and other products, allows context-dependent attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a crafted .ogg file.

The browser engine in Mozilla Firefox 3.5.x before 3.5.2 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to the TraceRecorder::snapshot function in js/src/jstracer.cpp, and unspecified other vectors.

Mozilla Firefox before 3.0.12, and 3.5.x before 3.5.2, allows remote SOCKS5 proxy servers to cause a denial of service (data stream corruption) via a long domain name in a reply.
