| Revision Date: | 2018-12-18 | Version: | 1 | | Title: | CVE-2018-16884 on Ubuntu 14.04 LTS (trusty) - medium. | | Description: | A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. Vasily Averin and Evgenii Shatokhin discovered that a use-after-free vulnerability existed in the NFS41+ subsystem when multiple network namespaces are in use. A local attacker in a container could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
