Synopsis

The remote openSUSE host is missing a security update.

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).

Solution

Update the affected the Linux Kernel packages.
