Description:
Drake Wilson 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 "hack-local-variables" function where local variables within a file are processed in an insecure manner. This can be exploited to e.g. modify a user's user-init-file and execute arbitrary Emacs Lisp code when a specially crafted file is opened.
Successful exploitation requires that "enable-local-variables" is set to ":safe".
The vulnerability is reported in version 22.1. Other versions may also be affected.
