The mozilla::net::FailDelayManager::Lookup function in the WebSockets implementation in Mozilla Firefox before 16.0.1, Thunderbird before 16.0.1, and SeaMonkey before 2.13.1 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unspecified vectors.
Mozilla Firefox 16.0, Thunderbird 16.0, and SeaMonkey 2.13 allow remote attackers to bypass the Same Origin Policy and read the properties of a Location object via a crafted web site, a related issue to CVE-2012-4193.
Mozilla Firefox before 16.0.1, Firefox ESR 10.x before 10.0.9, Thunderbird before 16.0.1, Thunderbird ESR 10.x before 10.0.9, and SeaMonkey before 2.13.1 omit a security check in the defaultValue function during the unwrapping of security wrappers, which allows remote attackers to bypass the Same Origin Policy and read the properties of a Location object, or execute arbitrary JavaScript code, via a crafted web site.
The Chrome Object Wrapper (COW) implementation in Mozilla Firefox before 16.0, Firefox ESR 10.x before 10.0.8, Thunderbird before 16.0, Thunderbird ESR 10.x before 10.0.8, and SeaMonkey before 2.13 does not properly interact with failures of InstallTrigger methods, which allows remote attackers to execute arbitrary JavaScript code with chrome privileges via a crafted web site, related to an "XrayWrapper pollution" issue.
The Inter-process Communication (IPC) implementation in Google Chrome before 18.0.1025.168, as used in Mozilla Firefox before 38.0 and other products, does not properly validate messages, which has unspecified impact and attack vectors.
Unspecified vulnerability in Mozilla Firefox 3.5.x before 3.5.16, Thunderbird before 3.0.11, and SeaMonkey before 2.0.11 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
Mozilla Firefox 3.6.x, 3.5.x, 3.0.19, and earlier, and SeaMonkey, executes a mail application in situations where an IFRAME element has a mailto: URL in its SRC attribute, which allows remote attackers to cause a denial of service (excessive application launches) via an HTML document with many IFRAME elements.
Mozilla Necko, as used in Thunderbird 3.0.1, SeaMonkey, and other applications, performs DNS prefetching even when the app type is APP_TYPE_MAIL or APP_TYPE_EDITOR, which makes it easier for remote attackers to determine the network location of the application's user by logging DNS requests, as demonstrated by DNS requests triggered by reading text/plain e-mail messages in Thunderbird.
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."
Heap-based buffer overflow in a regular-expression parser in Mozilla Network Security Services (NSS) before 3.12.3, as used in Firefox, Thunderbird, SeaMonkey, Evolution, Pidgin, and AOL Instant Messenger (AIM), allows remote SSL servers to cause a denial of service (application crash) or possibly execute arbitrary code via a long domain name in the subject's Common Name (CN) field of an X.509 certificate, related to the cert_TestHostName function.
