TITLE:
spider "read_file()" Potential Privilege Escalation Vulnerability

SECUNIA ADVISORY ID:
SA12716

VERIFY ADVISORY:
http://secunia.com/advisories/12716/

CRITICAL:
Not critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
spider 1.x
http://secunia.com/product/2185/

DESCRIPTION:
Emuadmin Security Team has reported a vulnerability in spider, which
potentially can be exploited by malicious, local users to gain
escalated privileges.

The vulnerability is caused due to a boundary error in the
"read_file()" function in "movelog.c". This can be exploited to cause
a buffer overflow by supplying an overly long string as argument to
the "-s" command line option.

Successful exploitation may allow execution of arbitrary code with
escalated privileges on systems, where the game has been installed
setuid or setgid (typically setgid "games").

The vulnerability has been reported in version 1.1. Other versions
may also be affected.

SOLUTION:
Remove any setuid / setgid bits.

Games should not be installed on production systems.

PROVIDED AND/OR DISCOVERED BY:
