______________________________________________________________________________

   An update that solves 5 vulnerabilities and has 56 fixes is
   now available.

Description:



   The SUSE Linux Enterprise 12 SP2 Realtime kernel was updated to 4.4.95 to
   receive various security and bugfixes.


   The following security bugs were fixed:

   - CVE-2017-12153: A security flaw was discovered in the
     nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux
     kernel This function did not check whether the required attributes are
     present in a Netlink request. This request can be issued by a user with
     the CAP_NET_ADMIN capability and may result in a NULL pointer
     dereference and system crash (bnc#1058410 1058624).
   - CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2) allowed
     reinstallation of the Group Temporal Key (GTK) during the group key
     handshake, allowing an attacker within radio range to replay frames from
     access points to clients (bnc#1063667).
   - CVE-2017-14489: The iscsi_if_rx function in
     drivers/scsi/scsi_transport_iscsi.c in the Linux kernel allowed local
     users to cause a denial of service (panic) by leveraging incorrect
     length validation (bnc#1059051).
   - CVE-2017-15265: Race condition in the ALSA subsystem in the Linux kernel
     allowed local users to cause a denial of service (use-after-free) or
     possibly have unspecified other impact via crafted /dev/snd/seq ioctl
     calls, related to sound/core/seq/seq_clientmgr.c and
     sound/core/seq/seq_ports.c (bnc#1062520).
   - CVE-2017-15649: net/packet/af_packet.c in the Linux kernel allowed local
     users to gain privileges via crafted system calls that trigger
     mishandling of packet_fanout data structures, because of a race
     condition (involving fanout_add and packet_do_bind) that leads to a
     use-after-free, a different vulnerability than CVE-2017-6346
     (bnc#1064388).
