The following security issues were fixed:
CVE-2018-17182: The vmacache_flush_all function in mm/vmacache.c
mishandled sequence number overflows. An attacker can trigger a
use-after-free (and possibly gain privileges) via certain thread
creation, map, unmap, invalidation, and dereference operations
(bsc#1110233).
CVE-2018-14634: An unprivileged local user with access to SUID (or
otherwise privileged) binary could use this flaw to escalate their
privileges on the system. Kernel versions 2.6.x, 3.10.x and 4.14.x are
believed to be vulnerable (bsc#1108963).
CVE-2018-14633: A security flaw was found in the
chap_server_compute_md5() function in the ISCSI target code in a way an
authentication request from an ISCSI initiator is processed. An
unauthenticated remote attacker can cause a stack buffer overflow and
smash up to 17 bytes of the stack. The attack requires the iSCSI target
to be enabled on the victim host. Depending on how the target's code was
built (i.e. depending on a compiler, compile flags and hardware
architecture) an attack may lead to a system crash and thus to a
denial-of-service or possibly to a non-authorized access to data
exported by an iSCSI target. Due to the nature of the flaw, privilege
escalation cannot be fully ruled out, although we believe it is highly
unlikely. (bsc#1107832).");
