Ubuntu Security Notice 3871-5 - Wen Xu discovered that a use-after-free vulnerability existed in the ext4 filesystem implementation in the Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service or possibly execute arbitrary code. Wen Xu discovered that a buffer overflow existed in the ext4 filesystem implementation in the Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
4b4d0eac27f8b493efdf43f83d8596ccUbuntu Security Notice 3878-2 - It was discovered that a race condition existed in the vsock address family implementation of the Linux kernel that could lead to a use-after-free condition. A local attacker in a guest virtual machine could use this to expose sensitive information. Cfir Cohen discovered that a use-after-free vulnerability existed in the KVM implementation of the Linux kernel, when handling interrupts in environments where nested virtualization is in use. A local attacker in a guest VM could possibly use this to gain administrative privileges in a host machine. Various other issues were also addressed.

9e099e4ba51ada496ad8b339ee89b49cUbuntu Security Notice 3871-4 - USN-3871-1 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. Wen Xu discovered that a use-after-free vulnerability existed in the ext4 filesystem implementation in the Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
36d11c033b19812d05a44d2b48c6688bUbuntu Security Notice 3871-2 - USN-3871-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.04 LTS. Unfortunately, that update introduced regressions with docking station displays and mounting ext4 file systems with the meta_bg option enabled. This update fixes the problems. Various other issues were also addressed.
