______________________________________________________________________________

An update that solves four vulnerabilities and has 86 fixes
is now available.

Description:



The openSUSE Leap 42.1 kernel was updated to receive various security and
bugfixes.

The following security bugs were fixed:

- CVE-2017-6074: The dccp_rcv_state_process function in net/dccp/input.c
in the Linux kernel mishandled DCCP_PKT_REQUEST packet data structures
in the LISTEN state, which allowed local users to cause a denial of
service (invalid free) or possibly have unspecified other impact via an
application that made an IPV6_RECVPKTINFO setsockopt system call
(bnc#1026024).
- CVE-2017-5986: Race condition in the sctp_wait_for_sndbuf function in
net/sctp/socket.c in the Linux kernel allowed local users to cause a
denial of service (assertion failure and panic) via a multithreaded
application that peels off an association in a certain buffer-full state
(bnc#1025235).
- CVE-2017-5970: The ipv4_pktinfo_prepare function in
net/ipv4/ip_sockglue.c in the Linux kernel allowed attackers to cause a
denial of service (system crash) via (1) an application that made
crafted system calls or possibly (2) IPv4 traffic with invalid IP
options (bnc#1024938).
- CVE-2017-5897: A potential remote denial of service within the IPv6 GRE
protocol was fixed. (bsc#1023762)
