The SUSE Linux Enterprise 12 kernel was updated to 3.12.67 to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2016-7042: The proc_keys_show function in     security/keys/proc.c in the Linux kernel used an     incorrect buffer size for certain timeout data, which     allowed local users to cause a denial of service (stack     memory corruption and panic) by reading the /proc/keys     file (bsc#1004517).

  - CVE-2016-7097: The filesystem implementation in the     Linux kernel preserved the setgid bit during a setxattr     call, which allowed local users to gain group privileges     by leveraging the existence of a setgid program with     restrictions on execute permissions (bsc#995968).

  - CVE-2015-8956: The rfcomm_sock_bind function in     net/bluetooth/rfcomm/sock.c in the Linux kernel allowed     local users to obtain sensitive information or cause a     denial of service (NULL pointer dereference) via vectors     involving a bind system call on a Bluetooth RFCOMM     socket (bnc#1003925).

  - CVE-2016-5696: net/ipv4/tcp_input.c in the Linux kernel     did not properly determine the rate of challenge ACK     segments, which made it easier for man-in-the-middle     attackers to hijack TCP sessions via a blind in-window     attack (bnc#989152).

  - CVE-2016-6130: Race condition in the sclp_ctl_ioctl_sccb     function in drivers/s390/char/sclp_ctl.c in the Linux     kernel allowed local users to obtain sensitive     information from kernel memory by changing a certain     length value, aka a 'double fetch' vulnerability     (bnc#987542).

  - CVE-2016-6327: drivers/infiniband/ulp/srpt/ib_srpt.c in     the Linux kernel allowed local users to cause a denial     of service (NULL pointer dereference and system crash)     by using an ABORT_TASK command to abort a device write     operation (bnc#994748).

  - CVE-2016-6480: Race condition in the ioctl_send_fib     function in drivers/scsi/aacraid/commctrl.c in the Linux     kernel allowed local users to cause a denial of service     (out-of-bounds access or system crash) by changing a     certain size value, aka a 'double fetch' vulnerability     (bnc#991608).

  - CVE-2016-6828: The tcp_check_send_head function in     include/net/tcp.h in the Linux kernel did not properly     maintain certain SACK state after a failed data copy,     which allowed local users to cause a denial of service     (tcp_xmit_retransmit_queue use-after-free and system     crash) via a crafted SACK option (bnc#994296).

  - CVE-2016-7425: The arcmsr_iop_message_xfer function in     drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did     not restrict a certain length field, which allowed local     users to gain privileges or cause a denial of service     (heap-based buffer overflow) via an     ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932).

  - CVE-2016-8658: Stack-based buffer overflow in the     brcmf_cfg80211_start_ap function in     drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg8021     1.c in the Linux kernel allowed local users to cause a     denial of service (system crash) or possibly have     unspecified other impact via a long SSID Information     Element in a command to a Netlink socket (bnc#1004462).

  - CVE-2016-8666: The IP stack in the Linux kernel allowed     remote attackers to cause a denial of service (stack     consumption and panic) or possibly have unspecified     other impact by triggering use of the GRO path for     packets with tunnel stacking, as demonstrated by     interleaved IPv4 headers and GRE headers, a related     issue to CVE-2016-7039 (bsc#1001486).

The update package also includes non-security fixes. See advisory for details.
