4) An error exists related to the NVIDIA graphics driver in glBufferData.
For more information see vulnerability #18 in:
SA49194
5) An error in the Mozilla updater can be exploited to load a wsock32.dll module from an application directory in a privileged context.
6) An error in the Mozilla updater service can be exploited to load an arbitrary DLL module in the context of the service.
7) An error in the Content Security Policy's (CSP) inline-script blocking feature can be exploited to bypass the cross-site scripting protection via e.g. "onclick" inline event handlers.
8) An error when loading HTML pages from Windows shares can be exploited to disclose files from local resources via e.g. an iframe tag.
9) A use-after-free error exists in "nsINode::ReplaceOrInsertBefore" when replacing or inserting a node in a document.
10) An error in QuickDER decoder is caused due to the Network Security Services (NSS) ASN.1 decoder not properly handling zero length items.
11) An error in "utf16_to_isolatin1" when converting from unicode to native character sets can be exploited to cause a heap-based buffer overflow.
12) A use-after-free error exists in "nsFrameList::FirstChild" when handling column layouts with absolute positioning within a container that changes the size.
13) An error in "nsHTMLReflowState::CalculateHypotheticalBox" when a window is resized on a page with nested columns using absolute and relative positioning can be exploited to cause a heap-based buffer overflow.
Successful exploitation of vulnerabilities #1 - 3, #9, and #11 - 13 may allow execution of arbitrary code.
Solution
