Description: The SUSE Linux Enterprise 11 SP4 Realtime kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - 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-2017-15274: security/keys/keyctl.c in the Linux kernel did not consider the case of a NULL payload in conjunction with a nonzero length value, which allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted add_key or keyctl system call, a different vulnerability than CVE-2017-12192 (bnc#1045327). - 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-2017-14489: 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-2017-1000253: Setuid root PIE binaries could still be exploited to gain local root access due missing overlapping memory checking in the ELF loader in the Linux Kernel. (bnc#1059525). The following non-security bugs were fixed: - blacklist.conf: blacklist bfedb589252c ("mm: Add a user_ns owner to mm_struct and fix ptrace permission checks") (bnc#1044228) - bnx2x: prevent crash when accessing PTP with interface down (bsc#1060665). - drm/mgag200: Fixes for G200eH3.
