1462147: CVE-2017-1000365 kernel: RLIMIT_STACK/RLIMIT_INFINITY string size limitation bypass

The MITRE CVE dictionary describes this issue as:

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.
