  script_tag(name:"insight", value:"The openSUSE Leap 15.0 was updated to receive various security and
  bugfixes.

  The following security bugs were fixed:

  - CVE-2019-10638: A device can be tracked by an attacker using the IP ID
  values the kernel produces for connection-less protocols (e.g., UDP and
  ICMP). When such traffic is sent to multiple destination IP addresses,
  it is possible to obtain hash collisions (of indices to the counter
  array) and thereby obtain the hashing key (via enumeration). An attack
  may be 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 allowed Information Exposure (partial
  kernel address disclosure), leading to a KASLR bypass. Specifically, it
  is possible to extract the KASLR kernel image offset using the IP ID
  values the kernel produces for connection-less protocols (e.g., UDP and
  ICMP). When such traffic is sent to multiple destination IP addresses,
  it is 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 is extracted (via enumeration), the offset of the kernel
  image is exposed. This attack can be carried out remotely, by the
  attacker forcing the target device to send UDP or ICMP (or certain
  other) 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. NOTE: this attack against KASLR became viable in 4.1 because
  IP ID generation was changed to have a dependency on an address
  associated with a network namespace (bnc#1140577).

  - CVE-2018-20836: There was a race condition 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
  mwifiex_uap_parse_tail_ies function in
  drivers/net/wireless/marvell/mwifiex/ie.c might lead to memory
  corruption and possibly other consequences (bnc#1136935).

  - CVE-2019-11599: The coredump implementation in the Linux kernel did not
  use locking or other mechanisms to prevent vma layout or vma flags
  changes while it runs, which allowed local users to obtain sensitive
  information, cause a denial of service, or pos ...
