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.

The remote host is affected by the vulnerability described in GLSA-201812-05 (EDE: Privilege escalation)

    An untrusted search path vulnerability was discovered in EDE.
  Impact :

    A local attacker could escalate his privileges via a specially crafted       Lisp expression in a Project.ede file in the directory or a parent       directory of an opened file.
  Workaround :

    There is no known workaround at this time.

The remote host is affected by the vulnerability described in GLSA-201403-05 (GNU Emacs: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in GNU Emacs:
      When &lsquo;global-ede-mode&rsquo; is enabled, EDE in Emacs automatically         loads a Project.ede file from the project directory (CVE-2012-0035).
      When &lsquo;enable-local-variables&rsquo;&rsquo; is set to &lsquo;:safe&rsquo;, Emacs         automatically processes eval forms (CVE-2012-3479).
  Impact :

    A remote attacker could entice a user to open a specially crafted file,       possibly resulting in execution of arbitrary code with the privileges of       the process or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

The remote host is affected by the vulnerability described in GLSA-201401-31 (CEDET: Privilege escalation)

    An untrusted search path vulnerability was discovered in CEDET.
  Impact :

    A local attacker could escalate his privileges via a specially crafted       Lisp expression in a Project.ede file in the directory or a parent       directory of an opened file.
  Workaround :

    There is no known workaround at this time.

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).

Hiroshi Oota discovered that Emacs incorrectly handled search paths.
If a user were tricked into opening a file with Emacs, a local attacker could execute arbitrary Lisp code with the privileges of the user invoking the program. (CVE-2012-0035)

Paul Ling discovered that Emacs incorrectly handled certain eval forms in local-variable sections. If a user were tricked into opening a specially crafted file with Emacs, a remote attacker could execute arbitrary Lisp code with the privileges of the user invoking the program. (CVE-2012-3479).
