SECUNIA ADVISORY ID:
SA31370

VERIFY ADVISORY:
http://secunia.com/advisories/31370/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Novell iPrint Client 4.x
http://secunia.com/product/14992/
Novell iPrint Client for Windows Vista 5.x
http://secunia.com/product/19621/

DESCRIPTION:
Secunia Research has discovered a vulnerability in Novell iPrint
Client, which can be exploited by malicious people to compromise a
user's system.

The vulnerability is caused due to a boundary error within the
"IppCreateServerRef()" function in nipplib.dll. This can be exploited
to cause a heap-based buffer overflow by passing an overly long,
specially crafted string as argument to certain methods provided by
the Novell iPrint ActiveX control (ienipp.ocx).

Successful exploitation may allow execution of arbitrary code.

The vulnerability is confirmed in versions 4.36, 5.04, and 5.06.
Other versions may also be affected.

SOLUTION:
Update to a fixed version.
