A vulnerability has been found in Mozilla Firefox and Thunderbird 23.0 (Web Browser) and classified as critical. This vulnerability affects the function nshtml5treebuilder::resettheinsertionmode of the component HTML5 Tree Builder. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The nsHtml5TreeBuilder::resetTheInsertionMode function in the HTML5 Tree Builder in Mozilla Firefox before 24.0, Thunderbird before 24.0, and SeaMonkey before 2.21 does not properly maintain the state of the insertion-mode stack for template elements, which allows remote attackers to execute arbitrary code or cause a denial of service (heap-based buffer over-read) by triggering use of this stack in its empty state.

The weakness was shared 09/17/2013 by Atte Kettunen (Inferno) with OUSPG as Mozilla Foundation Security Advisory 2013-77 as confirmed advisory (Website). The advisory is shared for download at mozilla.org. The vendor cooperated in the coordination of the public release. This vulnerability was named CVE-2013-1720 since 02/13/2013. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are known technical details, but no exploit is available.
