TITLE:
XASTIR Insecure Temporary Files

SECUNIA ADVISORY ID:
SA31677

VERIFY ADVISORY:
http://secunia.com/advisories/31677/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
XASTIR (X Amateur Tracking and Information System) 1.x
http://secunia.com/product/19750/

DESCRIPTION:
Some security issues have been reported in XASTIR (X Amateur Tracking
and Information System), which can be exploited by malicious, local
users to perform certain actions with escalated privileges.

The security issues are caused due to the scripts get-maptools.sh and
get_shapelib.sh creating temporary files in an insecure manner. This
can be exploited to overwrite arbitrary files with escalated
privileges via symlink attacks.

SOLUTION:
Restrict local access to trusted users only.

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