===================================================================== Red Hat Security Advisory
Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2019:2696-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2019:2696 Issue date: 2019-09-10 CVE Names: CVE-2018-9568 CVE-2018-13405 CVE-2018-16871 CVE-2018-16884 CVE-2019-1125 =====================================================================
1. Summary:
An update for kernel is now available for Red Hat Enterprise Linux 7.4 Extended Update Support.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux ComputeNode EUS (v. 7.4) - noarch, x86_64 Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.4) - x86_64 Red Hat Enterprise Linux Server EUS (v. 7.4) - noarch, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional EUS (v. 7.4) - ppc64, ppc64le, x86_64
3. Description:
The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):
* kernel: Memory corruption due to incorrect socket cloning (CVE-2018-9568)
* kernel: Missing check in fs/inode.c:inode_init_owner() does not clear SGID bit on non-directories for non-members (CVE-2018-13405)
* kernel: nfs: use-after-free in svc_process_common() (CVE-2018-16884)
* kernel: nfs: NULL pointer dereference due to an anomalized NFS message sequence (CVE-2018-16871)
* kernel: hw: Spectre SWAPGS gadget vulnerability (CVE-2019-1125)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
* fragmented packets timing out (BZ#1729411)
* kernel build: speed up debuginfo extraction (BZ#1731462)
* TCP packets are segmented when sent to the VM (TAP) (BZ#1732744)
* TCP packets are segmented when sent to the VLAN device when coming from VXLAN dev. (BZ#1732809)
* skb head copy occurs when sending traffic over OVS managed VXLAN tunnel (BZ#1733626)
* [mlx4] VXLAN over VLAN TCP segmentation (BZ#1734160)
* use "make -jN" for modules_install (BZ#1735081)
* shmem: consider shm_mnt as a long-term mount (BZ#1737376)
* [ESXi][RHEL7]use-after-free of scsi_cmnd on VMWare virtual guest with vmw_pvscsi and ata_piix (BZ#1737377)
* Backport TCP follow-up for small buffers (BZ#1739127)
