DESCRIPTION:
A security issue has been reported in Conky, which can be exploited
by malicious, local users to perform certain actions with escalated
privileges.

The security issue is caused due to Conky's "eve" module using the
"/tmp/.cesf" file in an insecure manner, which can be exploited to
e.g. overwrite arbitrary files with the privileges of the user
running Conky.

Successful exploitation requires that the "eve" module is compiled
and configured.

The security issue is reported in version 1.8.1. Other versions may
also be affected.

SOLUTION:
Restrict access to trusted users only.

PROVIDED AND/OR DISCOVERED BY:
Reported in an Ubuntu bug by segooon.
