USN-4227-1: Linux kernel vulnerabilities<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
It was discovered that a heap-based buffer overflow existed in the Marvell
\nWiFi-Ex Driver for the Linux kernel. A physically proximate attacker could
\nuse this to cause a denial of service (system crash) or possibly execute
\narbitrary code. (CVE-2019-14895, CVE-2019-14901)<\/p>\n
It was discovered that a heap-based buffer overflow existed in the Marvell
\nLibertas WLAN Driver for the Linux kernel. A physically proximate attacker
\ncould use this to cause a denial of service (system crash) or possibly
\nexecute arbitrary code. (CVE-2019-14896, CVE-2019-14897)<\/p>\n
It was discovered that the Fujitsu ES network device driver for the Linux
\nkernel did not properly check for errors in some situations, leading to a
\nNULL pointer dereference. A local attacker could use this to cause a denial
\nof service. (CVE-2019-16231)<\/p>\n
It was discovered that the QLogic Fibre Channel driver in the Linux kernel
\ndid not properly check for error, leading to a NULL pointer dereference. A
\nlocal attacker could possibly use this to cause a denial of service (system
\ncrash). (CVE-2019-16233)<\/p>\n
Anthony Steinhauser discovered that the Linux kernel did not properly
\nperform Spectre_RSB mitigations to all processors for PowerPC architecture
\nsystems in some situations. A local attacker could use this to expose
\nsensitive information. (CVE-2019-18660)<\/p>\n
It was discovered that the Mellanox Technologies Innova driver in the Linux
\nkernel did not properly deallocate memory in certain failure conditions. A
\nlocal attacker could use this to cause a denial of service (kernel memory
\nexhaustion). (CVE-2019-19045)<\/p>\n
It was discovered that Geschwister Schneider USB CAN interface driver in
\nthe Linux kernel did not properly deallocate memory in certain failure
\nconditions. A physically proximate attacker could use this to cause a
\ndenial of service (kernel memory exhaustion). (CVE-2019-19052)<\/p>\n
It was discovered that the AMD Display Engine Driver in the Linux kernel
\ndid not properly deallocate memory in certain error conditions. A local
\nattack could use this to cause a denial of service (memory exhaustion).
\n(CVE-2019-19083)<\/p>\n
It was discovered that the driver for memoryless force-feedback input
\ndevices in the Linux kernel contained a use-after-free vulnerability. A
\nphysically proximate attacker could possibly use this to cause a denial of
\nservice (system crash) or execute arbitrary code. (CVE-2019-19524)<\/p>\n
It was discovered that the Microchip CAN BUS Analyzer driver in the Linux
\nkernel contained a use-after-free vulnerability on device disconnect. A
\nphysically proximate attacker could use this to cause a denial of service
\n(system crash) or possibly execute arbitrary code. (CVE-2019-19529)<\/p>\n
It was discovered that the PEAK-System Technik USB driver in the Linux
\nkernel did not properly sanitize memory before sending it to the device. A
\nphysically proximate attacker could use this to expose sensitive
\ninformation (kernel memory). (CVE-2019-19534)<\/p>\n
Tristan Madani discovered that the ALSA timer implementation in the Linux
\nkernel contained a use-after-free vulnerability. A local attacker could use
\nthis to cause a denial of service (system crash) or possibly execute
\narbitrary code. (CVE-2019-19807)<\/p>\n
The problem can be corrected by updating your system to the following package versions:<\/p>\n
To update your system, please follow these instructions: https:\/\/wiki.ubuntu.com\/Security\/Upgrades<\/a>.<\/p>\n After a standard system update you need to reboot your computer to make ATTENTION: Due to an unavoidable ABI change the kernel updates have Source: USN-4227-1: Linux kernel vulnerabilities<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" USN-4227-1: Linux kernel vulnerabilities linux, linux-aws, linux-aws-hwe, linux-azure, linux-gcp, linux-gke-4.15, linux-hwe, linux-kvm, linux-oem, linux-oracle, linux-raspi2, linux-snapdragon vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 18.04 LTS Ubuntu 16.04 LTS Summary Several security issues were fixed in the Linux kernel.

\nall the necessary changes.<\/p>\n
\nbeen given a new version number, which requires you to recompile and
\nreinstall all third party kernel modules you might have installed.
\nUnless you manually uninstalled the standard kernel metapackages
\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
\nlinux-powerpc), a standard system upgrade will automatically perform
\nthis as well.<\/p>\nReferences<\/h2>\n
