TITLE:
mcweject Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA24641

VERIFY ADVISORY:
http://secunia.com/advisories/24641/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
mcweject 0.x
http://secunia.com/product/13784/

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

The vulnerability is caused due to a boundary error within eject.c
and can be exploited to cause a buffer overflow by providing an
overly large argument on the command line.

Successful exploitation may allow execution of arbitrary code with
escalated privileges, but requires that the application is installed
with the setuid bit set.

The vulnerability is reported in version 0.9. Other versions may also
be affected.

SOLUTION:
Remove the setuid bit.

Grant only trusted users access to affected systems.

PROVIDED AND/OR DISCOVERED BY:
