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).
