TITLE:
LessTif "DEBUG_FILE" Privilege Escalation Vulnerability

SECUNIA ADVISORY ID:
SA21428

VERIFY ADVISORY:
http://secunia.com/advisories/21428/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
LessTif 0.x
http://secunia.com/product/3956/

DESCRIPTION:
Karol Wiesek has reported a vulnerability in LessTif, which can be
exploited by malicious, local users to gain escalated privileges.

The vulnerability is caused due to the libXm library allowing users
to specify a file for writing debug output to via the "DEBUG_FILE"
environment variable. By running a setuid binary linked against a
vulnerable libXm library, this can be exploited to create
world-writable files with the effective user id of the binary.

SOLUTION:
Restrict permission to execute setuid binaries linked against libXm
to trusted users only.

PROVIDED AND/OR DISCOVERED BY:
Karol Wiesek
