gpdf crashes system opening specific file (DoS)
Last modified: 2007-11-30 17:10:51 EST
Opening the pdf file at the URL with gpdf causes gpdf to consume more
and more virtual memory eventually crashing the system and requiring a
This is reproducable as follows:
1) Download the file.
2) Open a terminal and run top.
3) Open a terminal and run gpdf Novell-52.pdf.
I see gnome-pdf-viewer immediately allocating ~ 600MB and continuing
to allocate memory until the system starts thrashing. Eventually, X
abruptly hangs and all disk activity ceases. I suspect that the kernel
has crashed at this point.
I've tried killing -9 gpdf & gnome-pdf-viewer during the thrashing
phase but the system still goes on to lock up.
This is with gdpf-0.131-2 & kernel-2.6.8-1.521smp. My system has 768MB
real memory & ~ 488MB of swap.
It works fine here with gpdf-2.8.0-2.
The recent update to gpdf-2.8.0-4.1.fc2 fixes this for FC2.
Does this still need to be addressed in FC1?
Oh apparently someone pushed it in updates already. No I dont think we
can backport this to FC1.
