Is my CentOS box with kenel 2.6.18-53.1.4.el5 vulnerable?

Valent

Yes. I tested it on both i386 and x86_64
Actually I tested 2.6.18-53.1.6.el5 but I have no doubt it would work in the 53.1.4 kernel.

On i386 - first attempt failed with a message "wtf" but second (w/o recompiling) attempt worked.

On x86_64 - I'm not sure why but I had to alter the exploit code to
#define PAGE_SIZE 4096
to get it to compile, but once compiled, it worked perfectly.
