Mozilla Seamonkey 2.0.11

Mozilla Firefox before 20.0 and SeaMonkey before 2.17, when gfx.color_management.enablev4 is used, do not properly handle color profiles during PNG rendering, which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (memory corruption) via a grayscale PNG image.

Mozilla Firefox before 23.0, Firefox ESR 17.x before 17.0.8, Thunderbird before 17.0.8, Thunderbird ESR 17.x before 17.0.8, and SeaMonkey before 2.20 do not properly handle the interaction between FRAME elements and history, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors involving spoofing a relative location in a previously visited document.

The JSSubScriptLoader in Mozilla Firefox 4.x through 6 and SeaMonkey before 2.4 does not properly handle XPCNativeWrappers during calls to the loadSubScript method in an add-on, which makes it easier for remote attackers to gain privileges via a crafted web site that leverages certain unwrapping behavior.

The Cascading Style Sheets (CSS) implementation in Mozilla Firefox before 4.0, Thunderbird before 3.3, and SeaMonkey before 2.1 does not properly handle the :visited pseudo-class, which allows remote attackers to obtain sensitive information about visited web pages via a crafted HTML document, a related issue to CVE-2010-2264.

Mozilla Firefox before 3.6.23 and 4.x through 5, Thunderbird before 6.0, and SeaMonkey before 2.3 do not properly handle "location" as the name of a frame, which allows remote attackers to bypass the Same Origin Policy via a crafted web site, a different vulnerability than CVE-2010-0170.

The txXPathNodeUtils::getXSLTId function in txMozillaXPathTreeWalker.cpp and txStandaloneXPathTreeWalker.cpp in Mozilla Firefox before 3.5.19, 3.6.x before 3.6.17, and 4.x before 4.0.1, and SeaMonkey before 2.0.14, allows remote attackers to obtain potentially sensitive information about heap memory addresses via an XML document containing a call to the XSLT generate-id XPath function.

The layout engine in Mozilla Firefox before 4.0, Thunderbird before 3.3, and SeaMonkey before 2.1 executes different code for visited and unvisited links during the processing of Cascading Style Sheets (CSS) token sequences, which makes it easier for remote attackers to obtain sensitive information about visited web pages via a timing attack.

The certificate-warning functionality in browser/components/certerror/content/aboutCertError.xhtml in Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.6, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.6, and SeaMonkey before 2.10 does not properly handle attempted clickjacking of the about:certerror page, which allows man-in-the-middle attackers to trick users into adding an unintended exception via an IFRAME element.

Mozilla Firefox before 3.6.23 and 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 do not prevent the starting of a download in response to the holding of the Enter key, which allows user-assisted remote attackers to bypass intended access restrictions via a crafted web site.

Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10 allow local users to obtain sensitive information via an HTML document that loads a shortcut (aka .lnk) file for display within an IFRAME element, as demonstrated by a network share implemented by (1) Microsoft Windows or (2) Samba.

Mozilla Firefox 4.x through 11.0, Thunderbird 5.0 through 11.0, and SeaMonkey before 2.9 do not properly construct the Origin and Sec-WebSocket-Origin HTTP headers, which might allow remote attackers to bypass an IPv6 literal ACL via a cross-site (1) XMLHttpRequest or (2) WebSocket operation involving a nonstandard port number and an IPv6 address that contains certain zero fields.

Mozilla Firefox 4.x through 9.0 and SeaMonkey before 2.7 on Linux and Mac OS X set weak permissions for Firefox Recovery Key.html, which might allow local users to read a Firefox Sync key via standard filesystem operations.
