DESCRIPTION:
Multiple vulnerabilities have been reported in Mozilla Firefox and
Mozilla Thunderbird, which can be exploited by malicious people to
bypass certain security restrictions, conduct cross-site scripting
attacks, and compromise a user's system.

1) Several unspecified errors in the browser engine can be exploited
to corrupt memory.

2) An error within the "image::RasterImage::DrawFrameTo()" function
when rendering GIF images can be exploited to cause a buffer
overflow.

3) An error within the "evalInSandbox()" function when handling the
"location.href" property can be exploited to bypass the sandbox and
e.g. conduct cross-site scripting attacks or read a local file.

4) An error when handling SVG text when setting CSS properties can be
exploited to corrupt memory.

5) The "Javascript:" URLs when opened in a New Tab page inherit the
privileges of the privileged "new tab" page and can be exploited to
e.g. execute locally installed programs.

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.

SOLUTION:
Upgrade to version 17.0.
