========================================================================== Ubuntu Security Notice USN-4228-2 January 07, 2020
linux-lts-xenial, linux-aws vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 ESM
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty
Details:
USN-4228-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 ESM.
It was discovered that a heap-based buffer overflow existed in the Marvell WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14895, CVE-2019-14901)
It was discovered that a heap-based buffer overflow existed in the Marvell Libertas WLAN Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14896, CVE-2019-14897)
Anthony Steinhauser discovered that the Linux kernel did not properly perform Spectre_RSB mitigations to all processors for PowerPC architecture systems in some situations. A local attacker could use this to expose sensitive information. (CVE-2019-18660)
It was discovered that Geschwister Schneider USB CAN interface driver in the Linux kernel did not properly deallocate memory in certain failure conditions. A physically proximate attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19052)
It was discovered that the driver for memoryless force-feedback input devices in the Linux kernel contained a use-after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2019-19524)
It was discovered that the PEAK-System Technik USB driver in the Linux kernel did not properly sanitize memory before sending it to the device. A physically proximate attacker could use this to expose sensitive information (kernel memory). (CVE-2019-19534)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 ESM: linux-image-4.4.0-1060-aws 4.4.0-1060.64 linux-image-4.4.0-171-generic 4.4.0-171.200~14.04.1 linux-image-4.4.0-171-generic-lpae 4.4.0-171.200~14.04.1 linux-image-4.4.0-171-lowlatency 4.4.0-171.200~14.04.1 linux-image-4.4.0-171-powerpc-e500mc 4.4.0-171.200~14.04.1 linux-image-4.4.0-171-powerpc-smp 4.4.0-171.200~14.04.1 linux-image-4.4.0-171-powerpc64-emb 4.4.0-171.200~14.04.1 linux-image-4.4.0-171-powerpc64-smp 4.4.0-171.200~14.04.1 linux-image-aws 4.4.0.1060.61 linux-image-generic-lpae-lts-xenial 4.4.0.171.150 linux-image-generic-lts-xenial 4.4.0.171.150 linux-image-lowlatency-lts-xenial 4.4.0.171.150 linux-image-powerpc-e500mc-lts-xenial 4.4.0.171.150 linux-image-powerpc-smp-lts-xenial 4.4.0.171.150 linux-image-powerpc64-emb-lts-xenial 4.4.0.171.150 linux-image-powerpc64-smp-lts-xenial 4.4.0.171.150 linux-image-virtual-lts-xenial 4.4.0.171.150
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
