Ubuntu Security Notice USN-3931-2
Posted Apr 3, 2019
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3931-2 - USN-3931-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 18.04 LTS for Ubuntu 16.04 LTS and for the Linux Azure kernel for Ubuntu 14.04 LTS. M. Vefa Bicakci and Andy Lutomirski discovered that the kernel did not properly set up all arguments to an error handler callback used when running as a paravirtualized guest. An unprivileged attacker in a paravirtualized guest VM could use this to cause a denial of service. Various other issues were also addressed.

Ubuntu Security Notice 3931-1 - M. Vefa Bicakci and Andy Lutomirski discovered that the kernel did not properly set up all arguments to an error handler callback used when running as a paravirtualized guest. An unprivileged attacker in a paravirtualized guest VM could use this to cause a denial of service. It was discovered that the KVM implementation in the Linux kernel on ARM 64bit processors did not properly handle some ioctls. An attacker with the privilege to create KVM-based virtual machines could use this to cause a denial of service or execute arbitrary code in the host. Various other issues were also addressed.

Ubuntu Security Notice 3930-1 - Mathias Payer and Hui Peng discovered a use-after-free vulnerability in the Advanced Linux Sound Architecture subsystem. A physically proximate attacker could use this to cause a denial of service. Shlomi Oberman, Yuli Shapiro, and Ran Menscher discovered an information leak in the Bluetooth implementation of the Linux kernel. An attacker within Bluetooth range could use this to expose sensitive information. Various other issues were also addressed.
