USN-76-1: Emacs vulnerability

7 February 2005

Emacs vulnerability



Max Vozeler discovered a format string vulnerability in the "movemail"
utility of Emacs. By sending specially crafted packets, a malicious
POP3 server could cause a buffer overflow, which could have been
exploited to execute arbitrary code with the privileges of the user
and the "mail" group (since "movemail" is installed as "setgid mail").

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 4.10
  • emacs21-bin-common -

In general, a standard system update will make all the necessary changes.
