Description:
Morten Welinder has reported a vulnerability in GNU Emacs, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an error in the processing of fast-lock files (.flc) for corresponding source files. This can be exploited to execute arbitrary Emacs Lisp code when e.g. a source file is opened and a specially crafted fast-lock file exists in the same directory.

Successful exploitation requires that "font-lock-support-mode" is set to "fast-lock-mode".

The vulnerability is reported in GNU Emacs 21.3.1. Other versions may also be affected.
