READ ONLINE:
http://www.secunia.com/advisories/9214/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

OPERATING SYSTEM:
Debian GNU/Linux 3.0

DESCRIPTION:
Debian has reported a vulnerability in skk/ddskk, which can be
exploited by malicious, local users to escalate their privileges on a
vulnerable system.

The vulnerability is caused due to insecure creation of temporary
files. This could potentially be exploited via a symlink attack to
overwrite arbitrary files with the privileges of the user running
Emacs and skk/ddskk.

SOLUTION:
Updated packages:
