Synopsis
========
The movemail utility shipped with Emacs and XEmacs contains several
format string vulnerabilities, potentially leading to the execution of
arbitrary code.
Background
==========
GNU Emacs and XEmacs are highly extensible and customizable text
editors. movemail is an Emacs utility that can fetch mail on remote
mail servers.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------

Description
===========
Max Vozeler discovered that the movemail utility contains several
format string errors.
Impact
======
An attacker could set up a malicious POP server and entice a user to
connect to it using movemail, resulting in the execution of arbitrary
code with the rights of the victim user.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Emacs users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-editors/emacs-21.4"
All XEmacs users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-editors/xemacs-21.4.15-r3"
