SubjectRe: how to determine if the noexec stack is defined by an application

like this:

$ eu-readelf -l /bin/true | grep STACK
GNU_STACK 0x000000 0x00000000 0x00000000 0x000000 0x000000 RW 0x4


(replace /bin/true with the binary or library you want to check)

if it says "RW" like here, it'll have non-executable stack. If it says
"RWX" or if this line is absent entirely, the stack will be executable.
