Mozilla Firefox — свободный браузер на движке Gecko

The jar: URI implementation in Mozilla Firefox before 3.0.9, Thunderbird, and SeaMonkey does not follow the Content-Disposition header of the inner URI, which allows remote attackers to conduct cross-site scripting (XSS) attacks and possibly other attacks via an uploaded .jar file with a "Content-Disposition: attachment" designation.

Mozilla Firefox before 3.0.9, Thunderbird, and SeaMonkey do not properly implement the Same Origin Policy for (1) XMLHttpRequest, involving a mismatch for a document's principal, and (2) XPCNativeWrapper.toString, involving an incorrect __proto__ scope, which allows remote attackers to conduct cross-site scripting (XSS) attacks and possibly other attacks via a crafted document.

The JavaScript engine in Mozilla Firefox 3.x before 3.0.9, Thunderbird before 2.0.0.22, and SeaMonkey before 1.1.16 allows remote attackers to cause a denial of service (application crash) and possibly trigger memory corruption via vectors involving (1) js_FindPropertyHelper, related to the definitions of Math and Date; and (2) js_CheckRedeclaration.

The JavaScript engine in Mozilla Firefox before 3.0.9, Thunderbird before 2.0.0.22, and SeaMonkey before 1.1.16 allows remote attackers to cause a denial of service (application crash) and possibly trigger memory corruption via vectors involving JSOP_DEFVAR and properties that lack the JSPROP_PERMANENT attribute.

Mozilla Firefox before 3.0.9 and SeaMonkey before 1.1.17 allow user-assisted remote attackers to obtain sensitive information via a web page with an embedded frame, which causes POST data from an outer page to be sent to the inner frame's URL during a SAVEMODE_FILEONLY save of the inner frame.

The browser engine in Mozilla Firefox 3.x before 3.0.9, Thunderbird before 2.0.0.22, and SeaMonkey before 1.1.16 allows remote attackers to cause a denial of service (application crash) and possibly trigger memory corruption via vectors related to (1) nsAsyncInstantiateEvent::Run, (2) nsStyleContext::Destroy, (3) nsComputedDOMStyle::GetWidth, (4) the xslt_attributeset_ImportSameName.html test case for the XSLT stylesheet compiler, (5) nsXULDocument::SynchronizeBroadcastListener, (6) IsBindingAncestor, (7) PL_DHashTableOperate and nsEditor::EndUpdateViewBatch, and (8) gfxSkipCharsIterator::SetOffsets, and other vectors.

The view-source: URI implementation in Mozilla Firefox before 3.0.9, Thunderbird, and SeaMonkey does not properly implement the Same Origin Policy, which allows remote attackers to (1) bypass crossdomain.xml restrictions and connect to arbitrary web sites via a Flash file; (2) read, create, or modify Local Shared Objects via a Flash file; or (3) bypass unspecified restrictions and render content via vectors involving a jar: URI.

Mozilla Firefox before 3.0.9, Thunderbird, and SeaMonkey do not properly implement the Same Origin Policy for (1) XMLHttpRequest, involving a mismatch for a document's principal, and (2) XPCNativeWrapper.toString, involving an incorrect __proto__ scope, which allows remote attackers to conduct cross-site scripting (XSS) attacks and possibly other attacks via a crafted document.

Cross-site scripting (XSS) vulnerability in Mozilla Firefox before 3.0.9, Thunderbird, and SeaMonkey allows remote attackers to inject arbitrary web script or HTML via vectors involving XBL JavaScript bindings and remote stylesheets, as exploited in the wild by a March 2009 eBay listing.

Cross-site scripting (XSS) vulnerability in the MozSearch plugin implementation in Mozilla Firefox before 3.0.9 allows user-assisted remote attackers to inject arbitrary web script or HTML via a javascript: URI in the SearchForm element.
