Gvisor Security Vulnerabilities

CVE-2018-16359

Google gVisor before 2018-08-23, within the seccomp sandbox, permits access to the renameat system call, which allows attackers to rename files on the host OS.

CVE-2018-19333

pkg/sentry/kernel/shm/shm.go in Google gVisor before 2018-11-01 allows attackers to overwrite memory locations in processes running as root (but not escape the sandbox) via vectors involving IPC_RMID shmctl calls, because reference counting is mishandled.

CVE-2018-20168

Google gVisor before 2018-08-22 reuses a pagetable in a different level with the paging-structure cache intact, which allows attackers to cause a denial of service ("physical address not valid" panic) via a crafted application.
