USN-4284-1: Linux kernel vulnerabilities linux, linux-aws, linux-azure-5.3, linux-gcp, linux-gcp-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-azure-5.3 – Linux kernel for Microsoft Azure Cloud systems linux-gcp-5.3 – Linux kernel for Google Cloud Platform (GCP) systems linux-hwe – Linux hardware enablement (HWE) kernel linux-raspi2-5.3 – Linux kernel for Raspberry Pi 2 Details It was discovered that the Linux kernel did not properly clear data structures on context [ more… ]

USN-4286-1: Linux kernel vulnerabilities linux, linux-aws, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 16.04 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-kvm – Linux kernel for cloud environments linux-raspi2 – Linux kernel for Raspberry Pi 2 linux-snapdragon – Linux kernel for Snapdragon processors Details It was discovered that the Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors. A local attacker could use this to expose sensitive information. (CVE-2019-14615) It was discovered that a race condition existed in the Softmac USB Prism54 device driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15220) [ more… ]

Software Description linux – Linux kernel linux-aws – Linux kernel for Amazon Web Services (AWS) systems linux-gke-4.15 – Linux kernel for Google Container Engine (GKE) 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-snapdragon – Linux kernel for Snapdragon processors linux-aws-hwe – Linux kernel for Amazon Web Services (AWS-HWE) systems linux-azure – Linux kernel for Microsoft Azure Cloud systems linux-gcp – Linux kernel for Google Cloud Platform (GCP) systems linux-hwe – Linux hardware enablement (HWE) kernel Details It was discovered that [ more… ]

USN-4285-1: Linux kernel vulnerabilities linux-aws-5.0, linux-azure, linux-gcp, linux-gke-5.0, linux-oracle-5.0 vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 18.04 LTS Summary Several security issues were fixed in the Linux kernel. Software Description linux-aws-5.0 – Linux kernel for Amazon Web Services (AWS) systems linux-azure – Linux kernel for Microsoft Azure Cloud systems linux-gcp – Linux kernel for Google Cloud Platform (GCP) systems linux-gke-5.0 – Linux kernel for Google Container Engine (GKE) systems linux-oracle-5.0 – Linux kernel for Oracle Cloud systems Details It was discovered that the Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors. A local attacker could use this to expose sensitive information. (CVE-2019-14615) It was discovered that the HSA Linux kernel driver for AMD GPU devices did not properly check for errors in certain situations, leading to [ more… ]

USN-4283-1: QEMU vulnerabilities qemu vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 19.10 Ubuntu 18.04 LTS Ubuntu 16.04 LTS Summary Several security issues were fixed in QEMU. Software Description qemu – Machine emulator and virtualizer Details Felipe Franciosi, Raphael Norwitz, and Peter Turschmid discovered that QEMU incorrectly handled iSCSI server responses. A remote attacker in control of the iSCSI server could use this issue to cause QEMU to crash, leading to a denial of service, or possibly execute arbitrary code. (CVE-2020-1711) It was discovered that the QEMU libslirp component incorrectly handled memory. A remote attacker could use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2020-7039, CVE-2020-8608) Update instructions The problem can be corrected by updating your system to the following package versions: Ubuntu 19.10 [ more… ]
