DESCRIPTION:
Eric Romang has reported a vulnerability in Elmo, which can be
exploited by malicious, local users to perform certain actions on a
vulnerable system with escalated privileges.

The vulnerability is caused due to the temporary file
"/tmp/elmostats" being created insecurely by the "stats_dump()"
function. This can be exploited via symlink attacks to create or
overwrite arbitrary files with the privileges of the user running the
affected application.

The vulnerability has been reported in versions 1.3.2-r1 and prior.

SOLUTION:
Grant only trusted users access to affected systems.
