Dear full-disclosure@xxxxxxxxxxxxxxxxx,
There is interesting thing with event logging on Windows. The only
security aspect of it is event log record tampering and performance
degradation, but it may become sensitive is some 3rd party software is
used for automated event log analysis.
The problem is a kind of "Format string" vulnerability where
user-supplied input is used for event log record. For ReportEvent()
function %1, %2, etc have a special meaning and are replaced with
corresponding string from lpStrings.
It looks more like a variable replacement (like $0 $1 ... in bash shell)
than a format string issue to me.
And it seems indeed to be a relevant information disclosure bug.
Cheers,
endrazine-
