USN-4211-1: 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 Zhipeng Xie discovered that an infinite loop could be triggered in the CFS Linux kernel process scheduler. A local attacker could possibly use this to cause a denial of service. (CVE-2018-20784) Nicolas Waisman discovered that the WiFi driver stack in the Linux kernel did not properly validate SSID lengths. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-17133) Nicolas Waisman [ more… ]

USN-4208-1: Linux kernel vulnerabilities linux, linux-aws, linux-gcp, linux-gcp-5.3, linux-kvm, linux-oracle 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-gcp-5.3 – Linux kernel for Google Cloud Platform (GCP) systems Details Jann Horn discovered that the OverlayFS and ShiftFS Drivers in the Linux kernel did not properly handle reference counting during memory mapping operations when used in conjunction with AUFS. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-15794) Nicolas Waisman [ more… ]

USN-4206-1: GraphicsMagick vulnerabilities graphicsmagick vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 16.04 LTS Summary Several security issues were fixed in GraphicsMagick. Software Description graphicsmagick – collection of image processing tools Details It was discovered that GraphicsMagick incorrectly handled certain image files. An attacker could possibly use this issue to cause a denial of service. (CVE-2017-10794, CVE-2017-10799, CVE-2017-11102, CVE-2017-11140, CVE-2017-11403, CVE-2017-11636, CVE-2017-11637, CVE-2017-13147, CVE-2017-14042, CVE-2017-6335) Update instructions The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS graphicsmagick – 1.3.23-1ubuntu0.2 libgraphicsmagick++-q16-12 – 1.3.23-1ubuntu0.2 libgraphicsmagick-q16-3 – 1.3.23-1ubuntu0.2 To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
