Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 do not properly restrict the role of property changes in triggering XUL tree removal, which allows remote attackers to cause a denial of service (deleted memory access and application crash) or possibly execute arbitrary code by setting unspecified properties.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
Race condition in the SPICE (aka spice-xpi) plug-in 2.2 for Firefox allows local users to obtain sensitive information, and conduct man-in-the-middle attacks, by providing a UNIX socket for communication between this plug-in and the client (aka qspice-client) in qspice 0.3.0, and then accessing this socket.
Untrusted search path vulnerability in Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 on Windows XP allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse dwmapi.dll that is located in the same folder as a .htm, .html, .jtx, .mfp, or .eml file.
layout/generic/nsObjectFrame.cpp in Mozilla Firefox 3.6.7 does not properly free memory in the parameter array of a plugin instance, which allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via a crafted HTML document, related to the DATA and SRC attributes of an OBJECT element. NOTE: this vulnerability exists because of an incorrect fix for CVE-2010-1214.
The nsIScriptableUnescapeHTML.parseFragment method in the ParanoidFragmentSink protection mechanism in Mozilla Firefox before 3.5.17 and 3.6.x before 3.6.14, Thunderbird before 3.1.8, and SeaMonkey before 2.0.12 does not properly sanitize HTML in a chrome document, which makes it easier for remote attackers to execute arbitrary JavaScript with chrome privileges via a javascript: URI in input to an extension, as demonstrated by a javascript:alert sequence in (1) the HREF attribute of an A element or (2) the ACTION attribute of a FORM element.
Mozilla Necko, as used in Firefox, SeaMonkey, and other applications, performs DNS prefetching of domain names contained in links within local HTML documents, which makes it easier for remote attackers to determine the network location of the application's user by logging DNS requests. NOTE: the vendor disputes the significance of this issue, stating "I don't think we necessarily need to worry about that case."
Race condition in Mozilla Firefox allows remote attackers to produce a JavaScript message with a spoofed domain association by writing the message in between the document request and document load for a web page in a different domain.
Visual truncation vulnerability in the MakeScriptDialogTitle function in nsGlobalWindow.cpp in Mozilla Firefox allows remote attackers to spoof the origin domain name of a script via a long name.
