An update that solves 11 vulnerabilities and has 95 fixes
is now available.


The SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.49 to receive
various security and bugfixes.

The following security bugs were fixed:

– CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg
function in net/socket.c in the Linux kernel allowed remote attackers to
execute arbitrary code via vectors involving a recvmmsg system call that
was mishandled during error processing (bnc#1003077).
– CVE-2017-5576: Integer overflow in the vc4_get_bcl function in
drivers/gpu/drm/vc4/vc4_gem.c in the VideoCore DRM driver in the Linux
kernel allowed local users to cause a denial of service or possibly have
other impact via a crafted size value in a VC4_SUBMIT_CL ioctl call
– CVE-2017-5577: The vc4_get_bcl function in drivers/gpu/drm/vc4/vc4_gem.c
in the VideoCore DRM driver in the Linux kernel did not set an errno
value upon certain overflow detections, which allowed local users to
cause a denial of service (incorrect pointer dereference and OOPS) via
inconsistent size values in a VC4_SUBMIT_CL ioctl call (bnc#1021294).
– CVE-2017-5551: The simple_set_acl function in fs/posix_acl.c in the
Linux kernel preserved the setgid bit during a setxattr call involving a
tmpfs filesystem, which allowed local users to gain group privileges by
leveraging the existence of a setgid program with restrictions on
execute permissions. (bnc#1021258).
– CVE-2017-2583: The load_segment_descriptor implementation in
arch/x86/kvm/emulate.c in the Linux kernel improperly emulated a “MOV
SS, NULL selector” instruction, which allowed guest OS users to cause a
denial of service (guest OS crash) or gain guest OS privileges via a
crafted application (bnc#1020602).
– CVE-2017-2584: arch/x86/kvm/emulate.c in the Linux kernel allowed local
users to obtain sensitive information from kernel memory or cause a
denial of service (use-after-free) via a crafted application that
leverages instruction emulation for fxrstor, fxsave, sgdt, and sidt
– 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”
– CVE-2016-9806: Race condition in the netlink_dump function in
net/netlink/af_netlink.c in the Linux kernel allowed local users to
cause a denial of service (double free) or possibly have unspecified
other impact via a crafted application that made sendmsg system calls,
leading to a free
operation associated with a new dump that started earlier than
anticipated (bnc#1013540).
– CVE-2017-5897: fixed a bug in the Linux kernel IPv6 implementation which
allowed remote attackers to trigger an out-of-bounds access, leading to
a denial-of-service attack (bnc#1023762).
– CVE-2017-5970: Fixed a possible denial-of-service that could have been
triggered by sending bad IP options on a socket (bsc#1024938).
– CVE-2017-5986: an application could have triggered a BUG_ON() in
sctp_wait_for_sndbuf() if the socket TX buffer was full, a thread was
on it to queue more data, and meanwhile another thread peeled off the
association being used by the first thread (bsc#1025235).
