TITLE:
Ampache "gather-messages.sh" Insecure Temporary Files

SECUNIA ADVISORY ID:
SA31657

VERIFY ADVISORY:
http://secunia.com/advisories/31657/

CRITICAL:
Not critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
Ampache 3.x
http://secunia.com/product/5347/

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

The security issue is caused due to the "gather-messages.sh" script
handling temporary files in an insecure manner. This can be exploited
via symlink attacks to overwrite arbitrary files with the privileges
of the user running the script.

NOTE: Reportedly, the script is only invoked when translating the
application.

The security issue is reported in version 3.4.1. Other versions may
also be affected.

SOLUTION:
Restrict local access to trusted users only.

PROVIDED AND/OR DISCOVERED BY:
Reported by Dmitry E. Oboukhov in a Debian bug report.
