Mozilla Firefox before 3.0.16 and 3.5.x before 3.5.6, and SeaMonkey before 2.0.1, allows remote attackers to associate spoofed content with an invalid URL by setting document.location to this URL, and then writing arbitrary web script or HTML to the associated blank document, a related issue to CVE-2009-2654.
Mozilla Firefox before 3.0.16 and 3.5.x before 3.5.6, and SeaMonkey before 2.0.1, allows remote attackers to execute arbitrary JavaScript with chrome privileges by leveraging a reference to a chrome window from a content window, related to the window.opener property.
The GeckoActiveXObject function in Mozilla Firefox before 3.0.16 and 3.5.x before 3.5.6, and SeaMonkey before 2.0.1, generates different exception messages depending on whether the referenced COM object is listed in the registry, which allows remote attackers to obtain potentially sensitive information about installed software by making multiple calls that specify the ProgID values of different COM objects.
Mozilla Firefox before 3.0.15 and 3.5.x before 3.5.4, and SeaMonkey before 2.0, allows remote attackers to execute arbitrary code via a crafted regular expression in a Proxy Auto-configuration (PAC) file.
Heap-based buffer overflow in the GIF image parser in Mozilla Firefox before 3.0.15 and 3.5.x before 3.5.4, and SeaMonkey before 2.0, allows remote attackers to execute arbitrary code via unspecified vectors.
Mozilla Firefox before 3.0.15 and 3.5.x before 3.5.4, and SeaMonkey before 2.0, does not properly handle a right-to-left override (aka RLO or U+202E) Unicode character in a download filename, which allows remote attackers to spoof file extensions via a crafted filename, as demonstrated by displaying a non-executable extension for an executable file.
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.
Mozilla Firefox before 2.0.0.19 and 3.x before 3.0.5, SeaMonkey, and Thunderbird allow remote attackers to cause a denial of service (memory consumption and application crash) via a large integer value for the length property of a Select object, a related issue to CVE-2009-1692.
Mozilla Thunderbird before 2.0.0.22 and SeaMonkey before 1.1.17 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a multipart/alternative e-mail message containing a text/enhanced part that triggers access to an incorrect object type.
Mozilla Firefox before 3.0.11, Thunderbird, and SeaMonkey do not check content policy before loading a script file into a XUL document, which allows remote attackers to bypass intended access restrictions via a crafted HTML document, as demonstrated by a "web bug" in an e-mail message, or web script or an advertisement in a web page.
