Test ID:1.3.6.1.4.1.25623.1.1.4.2019.14218.1
Category:SuSE Local Security Checks
Title:SUSE: Security Advisory (SUSE-SU-2019:14218-1)
Summary:The remote host is missing an update for the 'Linux Kernel' package(s) announced via the SUSE-SU-2019:14218-1 advisory.
Description:Summary:
The remote host is missing an update for the 'Linux Kernel' package(s) announced via the SUSE-SU-2019:14218-1 advisory.

Vulnerability Insight:
The SUSE Linux Enterprise 11-SP4 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:
CVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs
with Transactional Memory support could be used to facilitate
sidechannel information leaks out of microarchitectural buffers, similar
to the previously described 'Microarchitectural Data Sampling' attack.

The Linux kernel was supplemented with the option to disable TSX operation altogether (requiring CPU Microcode updates on older systems)
and better flushing of microarchitectural buffers (VERW).

The set of options available is described in our TID at [link moved to references] CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a
race condition in the Instruction Fetch Unit of the Intel CPU to cause a
Machine Exception during Page Size Change, causing the CPU core to be
non-functional.

The Linux Kernel kvm hypervisor was adjusted to avoid page size changes in executable pages by splitting / merging huge pages into small pages as needed. More information can be found on [link moved to references] CVE-2019-16233: drivers/scsi/qla2xxx/qla_os.c did not check the
alloc_workqueue return value, leading to a NULL pointer dereference.
(bsc#1150457).

CVE-2019-10220: Added sanity checks on the pathnames passed to the user
space. (bsc#1144903).

CVE-2019-16234: iwlwifi pcie driver did not check the alloc_workqueue
return value, leading to a NULL pointer dereference. (bsc#1150452).

CVE-2019-16232: Fix a potential NULL pointer dereference in the Marwell
libertas driver (bsc#1150465).

CVE-2019-17052: ax25_create in the AF_AX25 network module in the Linux
kernel did not enforce CAP_NET_RAW, which meant that unprivileged users
could create a raw socket, aka CID-0614e2b73768. (bnc#1152779)

CVE-2019-17055: base_sock_create in the AF_ISDN network module in the
Linux kernel did not enforce CAP_NET_RAW, which means that unprivileged
users can create a raw socket, aka CID-b91ee4aa2a21. (bnc#1152782)

CVE-2019-17054: atalk_create in the AF_APPLETALK network module in the
Linux kernel did not enforce CAP_NET_RAW, which means that unprivileged
users can create a raw socket, aka CID-6cc03e8aa36c. (bnc#1152786)

CVE-2019-17133: cfg80211 wireless extension did not reject a long SSID
IE, leading to a Buffer Overflow (bsc#1153158).

CVE-2019-17053: ieee802154_create in the AF_IEEE802154 network module in
the Linux kernel did not enforce CAP_NET_RAW, which means that
unprivileged users could create a raw socket, aka CID-e69dbd4619e7.
(bnc#1152789)

CVE-2019-16413: The 9p filesystem did not protect i_size_write()
properly, which caused an i_size_read() infinite loop and denial of
service on SMP systems. (bnc#1151347)

CVE-2019-15291: There was a NULL pointer dereference caused by a
malicious USB device in the ... [Please see the references for more information on the vulnerabilities]
