1) Introduction
===============


McAfee Framework is a framework used for building various services for
the McAfee products.
These services include HTTP servers and agents implemented, for
example, in McAfee ePolicy Orchestrator and possibly other products.

2) Bug
======


The logDetail function of applib.dll (which is just a link to
naimcomn_LogDetailW -> _naimcomn_Log in nailog2.dll) is used for adding
new log entries and is affected by a format string vulnerability caused
by the calling of vsnwprintf without the needed format argument.

In McAfee ePolicy Orchestrator this vulnerability can be exploited
through the sending of a simple UDP packet with a malformed sender,
package or computer field. The output log file Agent_HOSTNAME.log is
located in the Db folder.
