   An update that solves 9 vulnerabilities and has 70 fixes is
   now available.

Description:


   The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.57 to receive
   various security and bugfixes.

   The following security bugs were fixed:

   - CVE-2015-8812: A flaw was found in the CXGB3 kernel driver when the
     network was considered congested.  The kernel would incorrectly
     misinterpret the congestion as an error condition and incorrectly
     free/clean up the skb. When the device would then send the skb's queued,
     these structures would be referenced and may panic the system or allow
     an attacker to escalate privileges in a use-after-free scenario.
     (bsc#966437)
   - CVE-2015-8816: A malicious USB device could cause a kernel crash in the
     USB hub driver. (bnc#968010).
   - CVE-2016-2143: On zSeries a fork of a large process could have caused
     memory corruption due to incorrect page table handling. (bnc#970504)
   - CVE-2016-2184: A malicious USB device could cause a kernel crash in the
     alsa usb-audio driver. (bsc#971125).
   - CVE-2016-2384: A malicious USB device could cause a kernel crash in the
     alsa usb-audio driver. (bsc#966693)
   - CVE-2016-2782: A malicious USB device could cause a kernel crash in the
     usb visor driver. (bnc#968670).
   - CVE-2016-3139: A malicious USB device could cause a kernel crash in the
     wacom driver. (bnc#970909).
   - CVE-2016-3156: Removal of ipv4 interfaces with a large number of IP
     addresses was taking very long. (bsc#971360).
   - CVE-2015-8709: kernel/ptrace.c in the Linux kernel mishandled uid and
     gid mappings, which allowed local users to gain privileges by
     establishing a user namespace, waiting for a root process to enter that
     namespace with an unsafe uid or gid, and then using the ptrace system
     call.  NOTE: the vendor states "there is no kernel bug here (bnc#960561).
