Description Huzaifa S. Sidhpurwala 2016-03-08 15:13:07 UTC 
The Communications Electronics Security Group (UK) of the GCHQ reported a dangling pointer dereference within the Netscape Plugin Application Programming Interface (NPAPI) that could lead to the NPAPI subsystem crashing. This issue requires a maliciously crafted NPAPI plugin in concert with scripted web content, resulting in a potentially exploitable crash when triggered.
