Buffer overflow in Mozilla Firefox 3.6.x before 3.6.14, Thunderbird before 3.1.8, and SeaMonkey before 2.0.12 might allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted JPEG image.
Use-after-free vulnerability in Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, allows remote attackers to execute arbitrary code via vectors involving a change to an nsDOMAttribute node.
Integer overflow in the NewIdArray function in Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, allows remote attackers to execute arbitrary code via a JavaScript array with many elements.
Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, Thunderbird before 3.0.11 and 3.1.x before 3.1.7, and SeaMonkey before 2.0.11 do not properly validate downloadable fonts before use within an operating system's font implementation, which allows remote attackers to execute arbitrary code via vectors related to @font-face Cascading Style Sheets (CSS) rules.
The line-breaking implementation in Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, Thunderbird before 3.0.11 and 3.1.x before 3.1.7, and SeaMonkey before 2.0.11 on Windows does not properly handle long strings, which allows remote attackers to execute arbitrary code via a crafted document.write call that triggers a buffer over-read.
Multiple cross-site scripting (XSS) vulnerabilities in the rendering engine in Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, allow remote attackers to inject arbitrary web script or HTML via (1) x-mac-arabic, (2) x-mac-farsi, or (3) x-mac-hebrew characters that may be converted to angle brackets during rendering.
Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, does not properly handle injection of an ISINDEX element into an about:blank page, which allows remote attackers to execute arbitrary JavaScript code with chrome privileges via vectors related to redirection to a chrome: URI.
Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, does not properly calculate index values for certain child content in a XUL tree, which allows remote attackers to execute arbitrary code via vectors involving a DIV element within a treechildren element.
Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, when the XMLHttpRequestSpy module in the Firebug add-on is used, does not properly handle interaction between the XMLHttpRequestSpy object and chrome privileged objects, which allows remote attackers to execute arbitrary JavaScript via a crafted HTTP response. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-0179.
The NS_SecurityCompareURIs function in netwerk/base/public/nsNetUtil.h in Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, does not properly handle (1) about:neterror and (2) about:certerror pages, which allows remote attackers to spoof the location bar via a crafted web site.
