Subject: [v18.11 PATCH v2 1/2] vhost: fix possible denial of service on
SET_VRING_NUM
vhost_user_set_vring_num() performs multiple allocations
without checking whether data were previously allocated.
It may cause a denial of service because of the memory leaks
that happen if a malicious vhost-user master keeps sending
VHOST_USER_SET_VRING_NUM request until the slave runs out
of memory.
This issue has been assigned CVE-2019-14818
Reported-by: Jason Wang <jasowang@redhat.com>

Subject: [v18.11 PATCH v2 2/2] vhost: fix possible denial of service by
leaking FDs
A malicious Vhost-user master could send in loop hand-crafted
vhost-user messages containing more file descriptors the
vhost-user slave expects. Doing so causes the application using
the vhost-user library to run out of FDs.
This issue has been assigned CVE-2019-14818
Fixes: 8f972312b8f4 ("vhost: support vhost-user")
