CVE-2018-17963: qemu_deliver_packet_iov accepted packet sizes greater
than INT_MAX, which allows attackers to cause a denial of service or
possibly have unspecified other impact. (bsc#1111014)
CVE-2018-15468: The DEBUGCTL MSR contains several debugging features,
some of which virtualise cleanly, but some do not. In particular, Branch
Trace Store is not virtualised by the processor, and software has to be
careful to configure it suitably not to lock up the core. As a result,
it must only be available to fully trusted guests. Unfortunately, in the
case that vPMU is disabled, all value checking was skipped, allowing the
guest to choose any MSR_DEBUGCTL setting it likes. A malicious or buggy
guest administrator (on Intel x86 HVM or PVH) could have locked up the
entire host, causing a Denial of Service. (XSA-269) (bsc#1103276)

Kernel oops in fs/dcache.c called by d_materialise_unique() (bsc#1094508)");
