Package : emacs20
Vulnerability : format string
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2005-0100

Max Vozeler discovered several format string vulnerabilities in the movemail utility of Emacs, the well-known editor. Via connecting to a malicious POP server an attacker can execute arbitrary code under the privileges of group mail.

For the stable distribution (woody) these problems have been fixed in version 20.7-13.3.

The unstable distribution (sid) does not contain an Emacs20 package anymore.

We recommend that you upgrade your emacs packages.
