===============
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.
