"Security Fix(es) :

  - A flaw was found in the way the Linux kernel loaded ELF
    executables. Provided that an application was built as
    Position Independent Executable (PIE), the loader could
    allow part of that application's data segment to map
    over the memory area reserved for its stack, potentially
    resulting in memory corruption. An unprivileged local
    user with access to SUID (or otherwise privileged) PIE
    binary could use this flaw to escalate their privileges
    on the system. (CVE-2017-1000253, Important)");
