0d4ad75e1c0c0488c5fb0adc68d8e4c2c04aae6be649e37a8ba52aa3d7c799baUbuntu Security Notice 3777-3 - USN-3777-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.04 %LTS. This update provides the corresponding updates for the Linux kernel for Azure Cloud systems. Jann Horn discovered that the vmacache subsystem did not properly handle sequence number overflows, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or execute arbitrary code. Various other issues were also addressed.
769cc3a35204cab453698f34a6b0570d79e3ff0a88450698a2577c0e6fc6a664It was discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that is executing on the CPU core. This vulnerability is also known as L1 Terminal Fault (L1TF). A local attacker could use this to expose sensitive information (memory from the kernel or other processes). It was discovered that the paravirtualization implementation in the Linux kernel did not properly handle some indirect calls, reducing the effectiveness of Spectre v2 mitigations for paravirtual guests. A local attacker could use this to expose sensitive information. Various other issues were also addressed.
