-- CVE ID:

CVE-2008-4480

-- Affected Vendors:

Novell

-- Affected Products:

Novell eDirectory

-- TippingPoint(TM) IPS Customer Protection:

TippingPoint IPS customers have been protected against this

vulnerability by Digital Vaccine protection filter ID 6177.

For further product information on the TippingPoint IPS, visit:

-- Vulnerability Details:

This vulnerability allows remote attackers to execute arbitrary code on

vulnerable installations of Novell eDirectory Server. Authentication is

not required to exploit this vulnerability.

The specific flaw exists within dhost.exe, the service responsible for

directory replication which is bound by default to TCP port 524.

Improper parsing within opcode 0x24 via the Netware Core Protocol can

result in an arithmetic calculation based on supplied user-input

resulting in an under-allocated heap buffer. This fault can be leveraged

to result in arbitrary code execution.

-- Vendor Response:

Novell has issued an update to correct this vulnerability. More
