   An update that solves 10 vulnerabilities and has 18 fixes
   is now available.

Description:


   The Linux kernel for openSUSE Leap 42.1 was updated to the 4.1.15 stable
   release, and also includes security and bugfixes.

   Following security bugs were fixed:
   - CVE-2016-0728: A reference leak in keyring handling with
     join_session_keyring() could lead to local attackers gain root
     privileges. (bsc#962075).
   - CVE-2015-7550: A local user could have triggered a race between read and
     revoke in keyctl (bnc#958951).
   - CVE-2015-8767: A case can occur when sctp_accept() is called by the user
     during a heartbeat timeout event after the 4-way handshake. Since
     sctp_assoc_migrate() changes both assoc->base.sk and assoc->ep, the
     bh_sock_lock in sctp_generate_heartbeat_event() will be taken with the
     listening socket but released with the new association socket. The
     result is a deadlock on any future attempts to take the listening socket
     lock. (bsc#961509)
   - CVE-2015-8539: A negatively instantiated user key could have been used
     by a local user to leverage privileges (bnc#958463).
   - CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect functions in
     drivers/net/ppp/pptp.c in the Linux kernel did not verify an address
     length, which allowed local users to obtain sensitive information from
     kernel memory and bypass the KASLR protection mechanism via a crafted
     application (bnc#959190).
   - CVE-2015-8543: The networking implementation in the Linux kernel did not
     validate protocol identifiers for certain protocol families, which
     allowed local users to cause a denial of service (NULL function pointer
     dereference and system crash) or possibly gain privileges by leveraging
     CLONE_NEWUSER support to execute a crafted SOCK_RAW application
     (bnc#958886).
   - CVE-2015-8575: Validate socket address length in sco_sock_bind() to
     prevent information leak (bsc#959399).
   - CVE-2015-8551, CVE-2015-8552: xen/pciback: For
     XEN_PCI_OP_disable_msi[|x] only disable if device has MSI(X) enabled
     (bsc#957990).
   - CVE-2015-8550: Compiler optimizations in the XEN PV backend drivers     could have lead to double fetch vulnerabilities, causing denial of
     service or arbitrary code execution (depending on the configuration)
     (bsc#957988).
