______________________________________________________________________________

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).

Cross-References: CVE-2017-5897 CVE-2017-5970 CVE-2017-5986
CVE-2017-6074
Affected Products:
openSUSE Leap 42.2
______________________________________________________________________________

An update that solves four vulnerabilities and has 16 fixes
is now available.

Description:

The openSUSE Leap 42.2 kernel was updated to 4.4.49 to receive various
security and bugfixes.

The following security bugs were fixed:

– CVE-2017-5986: A userlevel triggerable BUG_ON on sctp_wait_for_sndbuf
was fixed. (bsc#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)
– 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 makes an IPV6_RECVPKTINFO setsockopt system call.
(bsc#1026024).

The following non-security bugs were fixed:

– btrfs: fix btrfs_compat_ioctl failures on non-compat ioctls
(bsc#1018100).
– iwlwifi: Expose the default fallback ucode API to module info
(boo#1021082, boo#1023884).
– kabi: protect struct tcp_fastopen_cookie (kabi).
– md: ensure md devices are freed before module is unloaded (bsc#1022304).
– md: Fix a regression reported by bsc#1020048 in
patches.fixes/0003-md-lockless-I-O-submission-for-RAID1.patch
(bsc#982783,bsc#998106,bsc#1020048).
– net: ethtool: Initialize buffer when querying device channel settings
(bsc#969479 FATE#320634).
– net: implement netif_cond_dbg macro (bsc#1019168).
– sfc: reduce severity of PIO buffer alloc failures (bsc#1019168).
– sfc: refactor debug-or-warnings printks (bsc#1019168).
– xfs_dmapi: fix the debug compilation of xfs_dmapi (bsc#989056).
– xfs: do not allow di_size with high bit set (bsc#1024234).
– xfs: exclude never-released buffers from buftarg I/O accounting
(bsc#1024508).
– xfs: fix broken multi-fsb buffer logging (bsc#1024081).
– xfs: fix buffer overflow dm_get_dirattrs/dm_get_dirattrs2 (bsc#989056).
– xfs: fix up xfs_swap_extent_forks inline extent handling (bsc#1023888).
– xfs: track and serialize in-flight async buffers against unmount
(bsc#1024508).
– xfs: track and serialize in-flight async buffers against unmount – kABI
(bsc#1024508).
