Ubuntu 11.10 / 12.04 LTS : emacs23 vulnerabilities (USN-1586-1)

Ubuntu Security Notice (C) 2012-2016 Canonical, Inc. / NASL script (C) 2012-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected emacs23 and / or emacs23-common packages.
