FreeBSD : emacs -- remote code execution vulnerability (c1e5f35e-f93d-11e1-b07f-00235a5f2c9a)

medium Nessus Plugin ID 62023

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

Chong Yidong reports :

Paul Ling has found a security flaw in the file-local variables code in GNU Emacs.

When the Emacs user option `enable-local-variables' is set to `:safe' (the default value is t), Emacs should automatically refuse to evaluate `eval' forms in file-local variable sections. Due to the bug, Emacs instead automatically evaluates such `eval' forms. Thus, if the user changes the value of `enable-local-variables' to `:safe', visiting a malicious file can cause automatic execution of arbitrary Emacs Lisp code with the permissions of the user.

The bug is present in Emacs 23.2, 23.3, 23.4, and 24.1.

Solution

Update the affected packages.
