Ubuntu Security Notice USN-4367-2
Posted May 29, 2020
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 4367-2 - USN-4367-1 fixed vulnerabilities in the 5.4 Linux kernel. Unfortunately, that update introduced a regression in overlayfs. This update corrects the problem. It was discovered that the btrfs implementation in the Linux kernel did not properly detect that a block was marked dirty in some situations. An attacker could use this to specially craft a file system image that, when unmounted, could cause a denial of service. Various other issues were also addressed.

An attacker could use this to specially craft a file system image that, when unmounted, could cause a denial of service. Tristan Madani discovered that the file locking implementation in the Linux kernel contained a race condition. A local attacker could possibly use this to cause a denial of service or expose sensitive information. Various other issues were also addressed.

An attacker could use this to specially craft a file system image that, when unmounted, could cause a denial of service. It was discovered that the linux kernel did not properly validate certain mount options to the tmpfs virtual memory file system. A local attacker with the ability to specify mount options could use this to cause a denial of service. Various other issues were also addressed.
