Mozilla Firefox — свободный браузер на движке Gecko

Visual truncation vulnerability in netwerk/dns/src/nsIDNService.cpp in Mozilla Firefox before 3.0.11 and SeaMonkey before 1.1.17 allows remote attackers to spoof the location bar via an IDN with invalid Unicode characters that are displayed as whitespace, as demonstrated by the \u115A through \u115E characters.

The JavaScript engine in Mozilla Firefox before 3.0.11, Thunderbird before 2.0.0.22, and SeaMonkey before 1.1.17 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to (1) js_LeaveSharpObject, (2) ParseXMLSource, and (3) a certain assertion in jsinterp.c; and other vectors.

Mozilla Firefox before 3.0.11 and SeaMonkey before 1.1.17 associate local documents with external domain names located after the file:// substring in a URL, which allows user-assisted remote attackers to read arbitrary cookies via a crafted HTML document, as demonstrated by a URL with file://example.com/C:/ at the beginning.

The browser engine in Mozilla Firefox 3 before 3.0.11, Thunderbird before 2.0.0.22, and SeaMonkey before 1.1.17 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to (1) nsEventStateManager::GetContentState and nsNativeTheme::CheckBooleanAttr; (2) UnhookTextRunFromFrames and ClearAllTextRunReferences; (3) nsTextFrame::ClearTextRun; (4) IsPercentageAware; (5) PL_DHashTableFinish; (6) nsListBoxBodyFrame::GetNextItemBox; (7) AtomTableClearEntry, related to the atom table, DOM mutation events, and Unicode surrogates; (8) nsHTMLEditor::HideResizers; and (9) nsWindow::SetCursor, related to changing the cursor; and other vectors.

The garbage-collection implementation in Mozilla Firefox before 3.0.11, Thunderbird before 2.0.0.22, and SeaMonkey before 1.1.17 sets an element's owner document to null in unspecified circumstances, which allows remote attackers to execute arbitrary JavaScript with chrome privileges via a crafted event handler, related to an incorrect context for this event handler.

Mozilla Firefox 3 before 3.0.11 associates an incorrect principal with a file: URL loaded through the location bar, which allows user-assisted remote attackers to bypass intended access restrictions and read files via a crafted HTML document, aka a "file-URL-to-file-URL scripting" attack.

Mozilla Firefox 3.0.10 allows remote attackers to cause a denial of service (infinite loop, application hang, and memory consumption) via a KEYGEN element in conjunction with (1) a META element specifying automatic page refresh or (2) a JavaScript onLoad event handler for a BODY element. NOTE: it was later reported that earlier versions are also affected.

The SVG component in Mozilla Firefox 3.0.4 allows remote attackers to cause a denial of service (application hang) via a large value in the r (aka Radius) attribute of a circle element, related to an "unclamped loop."
