  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.74 to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2017-1000365: The Linux Kernel imposes a size restriction on the
 arguments and environmental strings passed through
 RLIMIT_STACK/RLIM_INFINITY (1/4 of the size), but did not take the
 argument and environment pointers into account, which allowed attackers
 to bypass this limitation. (bnc#1039354).
- CVE-2017-1000380: sound/core/timer.c in the Linux kernel is vulnerable
 to a data race in the ALSA /dev/snd/timer driver resulting in local
 users being able to read information belonging to other users, i.e.,
 uninitialized memory contents may be disclosed when a read and an ioctl
 happen at the same time (bnc#1044125).
- CVE-2017-7346: The vmw_gb_surface_define_ioctl function in
 drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not
 validate certain levels data, which allowed local users to cause a
 denial of service (system hang) via a crafted ioctl call for a
 /dev/dri/renderD* device (bnc#1031796).
- CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c
 in the Linux kernel is too late in checking whether an overwrite of an
 skb data structure may occur, which allowed local users to cause a
 denial of service (system crash) via crafted system calls (bnc#1041431).
- CVE-2017-9076: The dccp_v6_request_recv_sock function in net/dccp/ipv6.c
 in the Linux kernel mishandled inheritance, which allowed local users to
 cause a denial of service or possibly have unspecified other impact via
 crafted system calls, a related issue to CVE-2017-8890 (bnc#1039885).
- CVE-2017-9077: The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c
 in the Linux kernel mishandled inheritance, which allowed local users to
 cause a denial of service or possibly have unspecified other impact via
 crafted system calls, a related issue to CVE-2017-8890 (bnc#1040069).
- CVE-2017-9075: The sctp_v6_create_accept_sk function in net/sctp/ipv6.c
 in the Linux kernel mishandled inheritance, which allowed local users to
 cause a denial of service or possibly have unspecified other impact via
 crafted system calls, a related issue to CVE-2017-8890 (bnc#1039883).
- CVE-2017-9074: The IPv6 fragmentation implementation in the Linux kernel
 did not consider that the nexthdr field may be associated with an
 invalid option, which allowed local users to cause a denial of service
 (out-of-bounds read and BUG) or possibly have unspecified other impact
 via crafted socket and send system calls (bnc#1039882).
- CVE-2017-8924: The edge_bulk_in_callback function in
 drivers/usb/serial/io_ti.c in the Linux kernel allowed local users to
 obtain sensitive information (in the dmesg ringbuffer and syslog) from
 uninitialized kernel memory by using a crafted USB device (posing as an
 io_ti USB serial device) to trigger an integer underflow. ... [Please see the references for more information on the vulnerabilities]");
