  script_tag(name:"insight", value:"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/cfg80211.c in the Linux
 kernel allowed local users to cause a denial of service ... [Please see the references for more information on the vulnerabilities]");
