   An update that fixes one vulnerability is now available.


   This update for the Linux Kernel 4.4.156-94_61 fixes one issue.

   The following security issue was fixed:

   - 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).
