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 ------------------------------------------------------------------- 1 app-editors/emacs < 21.4 >= 21.4 2 app-editors/xemacs < 21.4.15-r3 >= 21.4.15-r3 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. -------------------------------------------------------------------
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"
