CVE-2018-15746

qemu-seccomp.c in QEMU might allow local OS guest users to cause a denial of service (guest crash) by leveraging mishandling of the seccomp policy for threads other than the main thread.
Notes
| Author | Note |
|---|---|
| mdeslaur | we will not be fixing this issue on trusty and xenial. trust lacks a recent kernel and seccomp version and xenial uses a whitelist based approach instead of a blacklist. Fixing this in xenial is likely to cause regressions. |
