Package        : emacs21
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 21.2-1woody3.

For the unstable distribution (sid) these problems have been fixed in
version 21.3+1-9.

We recommend that you upgrade your emacs packages.
