Affected Products:
openSUSE Leap 42.2
______________________________________________________________________________

An update that solves 11 vulnerabilities and has 41 fixes
is now available.

Description:

The openSUSE Leap 42.2 kernel was updated to 4.4.56 fix various security
issues and bugs.

The following security bugs were fixed:

– CVE-2017-7184: The xfrm_replay_verify_len function in
net/xfrm/xfrm_user.c in the Linux kernel did not validate certain size
data after an XFRM_MSG_NEWAE update, which allowed local users to obtain
root privileges or cause a denial of service (heap-based out-of-bounds
access) by leveraging the CAP_NET_ADMIN capability, as demonstrated
during a Pwn2Own competition at CanSecWest 2017 for the Ubuntu 16.10
linux-image-* package 4.8.0.41.52 (bnc#1030573).
– CVE-2016-10200: Race condition in the L2TPv3 IP Encapsulation feature in
the Linux kernel allowed local users to gain privileges or cause a
denial of service (use-after-free) by making multiple bind system calls
without properly ascertaining whether a socket has the SOCK_ZAPPED
status, related to net/l2tp/l2tp_ip.c and net/l2tp/l2tp_ip6.c
(bnc#1028415).
– CVE-2017-2636: Race condition in drivers/tty/n_hdlc.c in the Linux
kernel allowed local users to gain privileges or cause a denial of
service (double free) by setting the HDLC line discipline (bnc#1027565).
– CVE-2017-6345: The LLC subsystem in the Linux kernel did not ensure that
a certain destructor exists in required circumstances, which allowed
local users to cause a denial of service (BUG_ON) or possibly have
unspecified other impact via crafted system calls (bnc#1027190).
– CVE-2017-6346: Race condition in net/packet/af_packet.c in the Linux
kernel allowed local users to cause a denial of service (use-after-free)
or possibly have unspecified other impact via a multithreaded
application that made PACKET_FANOUT setsockopt system calls
(bnc#1027189).
– CVE-2017-6353: net/sctp/socket.c in the Linux kernel did not properly
restrict association peel-off operations during certain wait states,
which allowed local users to cause a denial of service (invalid unlock
and double free) via a multithreaded application. NOTE: this
vulnerability exists because of an incorrect fix for CVE-2017-5986
(bnc#1025235).
– CVE-2017-6214: The tcp_splice_read function in net/ipv4/tcp.c in the
Linux kernel allowed remote attackers to cause a denial of service
(infinite loop and soft lockup) via vectors involving a TCP packet with
the URG flag (bnc#1026722).
– CVE-2016-2117: The atl2_probe function in
drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel incorrectly
enables scatter/gather I/O, which allowed remote attackers to obtain
sensitive information from kernel memory by reading packet data
(bnc#968697).
– CVE-2017-6347: The ip_cmsg_recv_checksum function in
net/ipv4/ip_sockglue.c in the Linux kernel has incorrect expectations
about skb data layout, which allowed local users to cause a denial of
service (buffer over-read) or possibly have unspecified other impact via
crafted system calls, as demonstrated by use of the MSG_MORE flag in
conjunction with loopback UDP transmission (bnc#1027179).
– CVE-2016-9191: The cgroup offline implementation in the Linux kernel
mishandled certain drain operations, which allowed local users to cause
a denial of service (system hang) by leveraging access to a container
environment for executing a crafted application, as demonstrated by
trinity (bnc#1008842).
– CVE-2017-2596: The nested_vmx_check_vmptr function in arch/x86/kvm/vmx.c
in the Linux kernel improperly emulates the VMXON instruction, which
allowed KVM L1 guest OS users to cause a denial of service (host OS
memory consumption) by leveraging the mishandling of page references
(bnc#1022785).
