> Hi all

> My patch which makes the header parsing more restrictive has an objection
> against it. and the only other developer who recently worked on it
> stated that he has no "time or motivation to deal with this and similar

> Assuming no fix without objections is found. What do people prefer ?
> Delay the 4.4 release ?
> Apply all non objected fixes and mark CFHD as experimental ?
> Something else ?

Start fixing professionally security issues.
Am not going to do someone else job.

> I wouldnt mind working on this but my approach of makeing the header
> parser more restrictive and do it in a way that is easy to backport,
> is unpopular and is in fact possibly just the first step in fixing this
> if the objection didnt exist.
> So comments and input from other developers is definitly welcome here!
