CVE-2017-6074

Affected Products:

openSUSE Leap 42.1

______________________________________________________________________________

 

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).
