    Description

      Security Fix(es):

      • A flaw was found in the way memory was being allocated on the stack for user
        space binaries. If heap (or different memory region) and stack memory regions
        were adjacent to each other, an attacker could use this flaw to jump over the
        stack guard gap, cause controlled memory corruption on process stack or the
        adjacent memory region, and thus increase their privileges on the system. This
        is a kernel-side mitigation which increases the stack guard gap size from one
        page to 1 MiB to make successful exploitation of this issue more difficult.
        (CVE-2017-1000364, Important)

      Bugs fixed (https://bugzilla.redhat.com/):

            el6 support of lustre on master is currently broken, as reported in LU-20
            This mod will never give +test for results using ldiskfs on el6.9 without a solution to that problem or reverting the offending mod.
