Affected Products:
                    SUSE Linux Enterprise Module for Public Cloud 15
                    SUSE Linux Enterprise Module for Open Buildservice Development Tools 15-SP1

   An update that solves 11 vulnerabilities and has 71 fixes
   is now available.


   The SUSE Linux Enterprise 15 kernel version 4.12.14 was updated to receive
   various security and bugfixes.

   The following security bugs were fixed:

   - CVE-2019-10638: Attackers used to be able to track the Linux kernel by
     the IP ID values the kernel produces for connection-less protocols. When
     such traffic was sent to multiple destination IP addresses, it was
     possible to
     obtain hash collisions (of indices to the counter array) and thereby
      obtain the hashing key (via enumeration). An attack could have been
      conducted by hosting a crafted web page that uses WebRTC or gQUIC to
      force UDP traffic to attacker-controlled IP addresses. [bnc#1140575]

   - CVE-2019-10639: The Linux kernel used to allow Information Exposure
     (partial kernel address disclosure), leading to a KASLR bypass.
     Specifically, it was possible to extract the KASLR kernel image offset
     using the IP ID values the kernel produces for connection-less
     protocols. When such traffic was sent to multiple destination IP
     addresses, it was possible to obtain hash collisions (of indices to the
     counter array) and thereby obtain the hashing key (via enumeration).
     This key contains enough bits from a kernel address (of a static
     variable) so when the key was extracted (via enumeration), the offset
     of the kernel image was exposed. This attack could be carried out
      remotely by the attacker forcing the target device to send UDP or ICMP
      traffic to attacker-controlled IP addresses. Forcing a server to send
      UDP traffic is trivial if the server is a DNS server. ICMP traffic is
      trivial if the server answers ICMP Echo requests (ping). For client
      targets, if the target visits the attacker's web page, then WebRTC or
      gQUIC can be used to force UDP traffic to attacker-controlled IP
      addresses. [bnc#1140577]

   - CVE-2018-20836: A race condition used to exist in smp_task_timedout()
     and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a
     use-after-free. [bnc#1134395]

   - CVE-2019-10126: A heap based buffer overflow in the wireless driver code
     was fixed. This issue might have lead to memory corruption and possibly
     other consequences. [bnc#1136935]

   - CVE-2019-11599: The coredump implementation did not use locking or other
     mechanisms to prevent vma layout or vma flags changes while it ran,
     which allowed local users to obtain sensitive information, cause a
     denial of service, or possibly have unspecified other impact by
     triggering a race condition with mmget_not_zero or get_task_mm calls.

   - CVE-2019-12614: There was an unchecked kstrdup of prop->name on PowerPC
     platforms, which allowed an attacker to cause a denial of service (NULL
     pointer dereference and system crash). [bnc#1137194]

   - CVE-2018-16871: A flaw was found in the NFS implementation. An attacker
     who was able to mount an exported NFS filesystem was able to trigger a
     null pointer dereference by an invalid NFS sequence. This could panic
     the machine and deny access to the NFS server. Any outstanding disk
     writes to the NFS server will were lost. [bnc#1137103]

   - CVE-2019-12819: The function __mdiobus_register() used to call
     put_device(), which would trigger a fixed_mdio_bus_init use-after-free
     error. This would cause a denial of service. [bnc#1138291]

   - CVE-2019-12818: The nfc_llcp_build_tlv function in
     net/nfc/llcp_commands.c may return NULL. If the caller did not check for
     this, it could trigger a NULL pointer dereference. This would cause
     denial of service. [bnc#1138293]

   - CVE-2019-12456: An issue in the MPT3COMMAND case in _ctl_ioctl_main()
     allowed local users to cause a denial of service or possibly have
     unspecified other impact by changing the value of ioc_number between two
     kernel reads of that value, aka a "double fetch" vulnerability.

   - CVE-2019-12380: An issue was in the EFI subsystem existed that
     mishandled memory allocation failures. Note, however, that all relevant
     code runs only at boot-time, before any user processes are started.
     Therefore, there was no possibility for an unprivileged user to exploit
     this issue. [bnc#1136598]
