Information regarding a simple mitigation to disable 32bit binaries in Linux.
bb3916c0b24327094327e352079c4739
If you do not actually need to run any 32bits binaries on x86_64 you can
do:
echo ':32bits:M:0:\x7fELF\x01::/bin/echo:' > /proc/sys/fs/binfmt_misc/register
This will make the kernel run /bin/echo filename instead of executing
the file whenever it sees a 32bit ELF binary.
Of course if you actually *need* to run some 32bits binaries this will
not help you.
