The Linux Kernel imposes a size restriction on the arguments and
environmental strings passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the
size), but does not take the argument and environment pointers into
account, which allows attackers to bypass this limitation. This affects
Linux Kernel versions 4.11.5 and earlier. It appears that this feature was
introduced in the Linux Kernel version 2.6.23.
