--===============4572444025033027370== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="KN5l+BnMqAQyZLvT" Content-Disposition: inline --KN5l+BnMqAQyZLvT Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-4300-1 March 16, 2020 linux, linux-aws, linux-gcp, linux-gcp-5.3, linux-gke-5.3, linux-hwe, linux-kvm, linux-oracle, linux-raspi2, linux-raspi2-5.3 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 19.10 - Ubuntu 18.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-kvm: Linux kernel for cloud environments - linux-oracle: Linux kernel for Oracle Cloud systems - linux-raspi2: Linux kernel for Raspberry Pi 2 - linux-gcp-5.3: Linux kernel for Google Cloud Platform (GCP) systems - linux-gke-5.3: Linux kernel for Google Container Engine (GKE) systems - linux-hwe: Linux hardware enablement (HWE) kernel - linux-raspi2-5.3: Linux kernel for Raspberry Pi 2 Details: It was discovered that the KVM implementation in the Linux kernel, when paravirtual TLB flushes are enabled in guests, the hypervisor in some situations could miss deferred TLB flushes or otherwise mishandle them. An attacker in a guest VM could use this to expose sensitive information (read memory from another guest VM). (CVE-2019-3016) Paulo Bonzini discovered that the KVM hypervisor implementation in the Linux kernel could improperly let a nested (level 2) guest access the resources of a parent (level 1) guest in certain situations. An attacker could use this to expose sensitive information. (CVE-2020-2732) It was discovered that the Afatech AF9005 DVB-T USB device driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-18809) It was discovered that the Intel(R) XL710 Ethernet Controller device driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19043) It was discovered that the RPMSG character device interface in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19053) It was discovered that the Marvell Wi-Fi device driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could use this to possibly cause a denial of service (kernel memory exhaustion). (CVE-2019-19056) It was discovered that the Intel(R) Wi-Fi device driver in the Linux kernel device driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19058, CVE-2019-19059) It was discovered that the Serial Peripheral Interface (SPI) driver in the Linux kernel device driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19064) It was discovered that the Brocade BFA Fibre Channel device driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19066) It was discovered that the Realtek RTL8xxx USB Wi-Fi device driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19068) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 19.10: linux-image-5.3.0-1011-oracle 5.3.0-1011.12 linux-image-5.3.0-1012-kvm 5.3.0-1012.13 linux-image-5.3.0-1013-aws 5.3.0-1013.14 linux-image-5.3.0-1014-gcp 5.3.0-1014.15 linux-image-5.3.0-1019-raspi2 5.3.0-1019.21 linux-image-5.3.0-42-generic 5.3.0-42.34 linux-image-5.3.0-42-generic-lpae 5.3.0-42.34 linux-image-5.3.0-42-lowlatency 5.3.0-42.34 linux-image-5.3.0-42-snapdragon 5.3.0-42.34 linux-image-aws 5.3.0.1013.15 linux-image-gcp 5.3.0.1014.15 linux-image-generic 5.3.0.42.36 linux-image-generic-lpae 5.3.0.42.36 linux-image-gke 5.3.0.1014.15 linux-image-kvm 5.3.0.1012.14 linux-image-lowlatency 5.3.0.42.36 linux-image-oracle 5.3.0.1011.12 linux-image-raspi2 5.3.0.1019.16 linux-image-snapdragon 5.3.0.42.36 linux-image-virtual 5.3.0.42.36 Ubuntu 18.04 LTS: linux-image-5.3.0-1014-gcp 5.3.0-1014.15~18.04.1 linux-image-5.3.0-1014-gke 5.3.0-1014.15~18.04.1 linux-image-5.3.0-1019-raspi2 5.3.0-1019.21~18.04.1 linux-image-5.3.0-42-generic 5.3.0-42.34~18.04.1 linux-image-5.3.0-42-generic-lpae 5.3.0-42.34~18.04.1 linux-image-5.3.0-42-lowlatency 5.3.0-42.34~18.04.1 linux-image-gcp-edge 5.3.0.1014.13 linux-image-generic-hwe-18.04 5.3.0.42.99 linux-image-generic-lpae-hwe-18.04 5.3.0.42.99 linux-image-gke-5.3 5.3.0.1014.4 linux-image-lowlatency-hwe-18.04 5.3.0.42.99 linux-image-raspi2-hwe-18.04 5.3.0.1019.8 linux-image-snapdragon-hwe-18.04 5.3.0.42.99 linux-image-virtual-hwe-18.04 5.3.0.42.99 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.
