Hello everyone.
Some minutes ago I found this video about an exploit in Emacs:
https://www.youtube.com/watch?v=kBidbz3Oohw
The effect of the exploit is, apparently: When you open a file, Emacs
run some embedded ELISP code without asking you anything.
On the video, the exploit is called "emacs_enriched" and the description
said: Emacs Enriched Mime-type Handle Arbitrary ELISP Execution
I didn't find anything more about the exploit itself. It's seems to be
provided by a paying and proprietary software named "Immunity canvas".
Did this exploit has got already reported?
Best regards
