The problem here is that the /usr/Brother/Printer/mfc440cn/cupswrapper/brcupsconfpt1 file is returning a

*** stack smashing detected ***

error. There is a buffer overrun in the char media_command variable in the brcupsconfig.c file. A quick (and rather bad) fix is to make the array larger.

I changed the

char media_command[100];


char media_command[200];

and the driver works. I have attached my version of the file (I enabled debugging and added more debugging). Just change the line in the Ubuntu version of the file and it works. Ignore all of my excess debug statements.

The package brother-cups-wrapper-common (in Universe) and all other brother-... packages are not maintained any more. We should consider removing them.

The crash is most probably in closed-source code from Brother and probably fixed in their current driver version on their web site.

This crash is NOT due to any proprietary code, or binary blob. There is a really simple fix for it (that I posted way back in 2010-04-06).

Look at comment #4. My fix isn't great, btw. You could still get a buffer overflow. The correct solution would be to check the size of the exec string before loading it to make sure that it is not longer than the size of the media_command array.

Corection from #4 solves the problem.
I put 1000 because 200 was not sufficient for me.

Subject: Hey put my dick back in!

Exactly how is it distributed? 10 points is 2/3 of 1 SD for IQ, which would cover about 50 of the population, as opposed to the middle they were in previously. Alternatively, the smartest person in the world drops to being just in the top 100. Are each of these a large drop in intelligence? I think that's only answerable by opinion, with quite a bit of guessing required, and on a case by case basis.
