ZDI-09-016: Novell Client/NetIdentity Agent Remote Arbitrary Pointer
Dereference Code Execution Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-09-016
April 6, 2009

-- Affected Vendors:
Novell

-- Affected Products:
Novell Netware

-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Novell Netware. A valid IPC$ connection must
be established in order to exploit this vulnerability.

The specific flaw exists within xtagent.exe during the handling of RPC
messages over the XTIERRPCPIPE named pipe. Insufficient sanity checking
allows remote attackers to dereference an arbitrary pointer which can be
leveraged to execute code under the context of the system user.

-- Vendor Response:
Novell has issued an update to correct this vulnerability. More
