CVE-2018-15746 QEMU: seccomp: blacklist is not applied to all threads
An issue was found in the way QEMU implements Seccomp sandboxing. In that, all QEMU threads are not bound by the sandbox. A guest user/process maybe be able to use this flaw to invoke prohibited system calls on a host, resulting in guest crash.
