2019-07-23 KENNETH 0

USN-4069-1: Linux kernel vulnerabilities linux, linux-aws, linux-azure, linux-gcp, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 19.04 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-azure – Linux kernel for Microsoft Azure Cloud systems linux-gcp – Linux kernel for Google Cloud Platform (GCP) 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 an integer overflow existed in the Linux kernel when reference counting pages, leading to potential use-after-free issues. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-11487) Jann Horn discovered that a race [ more… ]
