Mandriva Linux Security Advisory 2013-076 - Untrusted search path vulnerability in EDE in CEDET before 1.0.1, as used in GNU Emacs before 23.4 and other products, allows local users to gain privileges via a crafted Lisp expression in a Project.ede file in the directory, or a parent directory, of an opened file. lisp/files.el in Emacs 23.2, 23.3, 23.4, and 24.1 automatically executes eval forms in local-variable sections when the enable-local-variables option is set to :safe, which allows user-assisted remote attackers to execute arbitrary Emacs Lisp code via a crafted file. Additionally a problem was fixed reading xz compressed files.

Package : emacs
Date : April 8, 2013
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Updated emacs packages fix security vulnerabilities:

Untrusted search path vulnerability in EDE in CEDET before 1.0.1, as
used in GNU Emacs before 23.4 and other products, allows local users
to gain privileges via a crafted Lisp expression in a Project.ede
file in the directory, or a parent directory, of an opened file
(CVE-2012-0035).

lisp/files.el in Emacs 23.2, 23.3, 23.4, and 24.1 automatically
executes eval forms in local-variable sections when the
enable-local-variables option is set to :safe, which allows
user-assisted remote attackers to execute arbitrary Emacs Lisp code
via a crafted file (CVE-2012-3479).

Additionally a problem was fixed reading xz compressed files
(mga#7759).
