NOTE: This vulnerability only affects Firefox. 6) An integer underflow error within the "str_unescape()" function can be exploited to cause a heap-based buffer overflow. 7) The "XMLHttpRequest" objects created within sandboxes are created with system principal instead of the sandbox principal and can be exploited to e.g conduct cross-site request forgery attacks. 8) An error when handling XrayWrappers can be exploited to disclose chrome-only properties. 9) An error within certain wrappers can be exploited to bypass the same-origin policy and conduct cross-site scripting attacks. 10) An error when handling HZ-GB-2312 charset encoding can be exploited to conduct cross-site scripting attacks. 11) The Developer Toolbar allows script to be executed in chrome privileged context. NOTE: This vulnerability only affects Firefox. 12) An error when handling the "location" object can be exploited to shadow the property. 13) An error within Style Inspector when parsing stylesheets can be exploited to execute HTML and CSS code in chrome privileged context. 14) Some use-after-free errors exist within the "nsTextEditorState::PrepareEditor()", "nsPlaintextEditor::FireClipboardEvent()", "gfxFont::GetFontEntry()", "nsTextEditorState::PrepareEditor()", "XPCWrappedNative::Mark()", "nsEditor::FindNextLeafNode()", "nsViewManager::ProcessPendingUpdates()", and "BuildTextRunsScanner::BreakSink::SetBreaks()" functions. 15) Some errors within the "nsWindow::OnExposeEvent()" and "gfxShapedWord::CompressedGlyph::IsClusterStart()" functions can be exploited to cause heap-based buffer overflows. 16) A use-after-free error exists when loading html file. NOTE: This vulnerability only affects OS X. 17) An unspecified error in certain texImage2D calls can be exploited to corrupt memory. 18) An integer overflow error exists when handling the webgl bufferdata. 19) An error within copyTexImage2D when handling image dimensions can be exploited to corrupt memory.
