CVE-2017-15119 Eric Blake discovered that the NBD server insufficiently restricts large option requests, resulting in denial of service.
CVE-2017-15124 Daniel Berrange discovered that the integrated VNC server insufficiently restricted memory allocation, which could result in denial of service.
CVE-2017-15268 A memory leak in websockets support may result in denial of service.
CVE-2017-15289 Guoxiang Niu discovered an OOB write in the emulated Cirrus graphics adaptor which could result in denial of service.
CVE-2017-16845 Cyrille Chatras discovered an information leak in PS/2 mouse and keyboard emulation which could be exploited during instance migration.
CVE-2017-17381 Dengzhan Heyuandong Bijunhua and Liweichao discovered that an implementation error in the virtio vring implementation could result in denial of service.
CVE-2017-18043 Eric Blake discovered an integer overflow in an internally used macro which could result in denial of service.
