TITLE:
GSAMBAD "populate_conns()" Insecure Temporary Files

SECUNIA ADVISORY ID:
SA25909

VERIFY ADVISORY:
http://secunia.com/advisories/25909/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
GSAMBAD 0.x
http://secunia.com/product/14685/

DESCRIPTION:
Steve Kemp has reported a security issue in GSAMBAD, which can be
exploited by malicious, local users to perform certain actions with
escalated privileges.

The security issue is caused due to the "populate_conns()" function
in src/populate_conns.c creating 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
application (usually root).

SOLUTION:
Restrict access to trusted users only.
