- CVE-2017-12855: Premature clearing of GTF_writing / GTF_reading lead to
 potentially leaking sensitive information (XSA-230, bsc#1052686).
- CVE-2017-12135: Unbounded recursion in grant table code allowed a malicious
 guest to crash the host or potentially escalate privileges/leak information
 (XSA-226, bsc#1051787).
- CVE-2017-12137: Incorrectly-aligned updates to pagetables allowed for
 privilege escalation (XSA-227, bsc#1051788).
- CVE-2017-11334: The address_space_write_continue function in exec.c allowed
 local guest OS privileged users to cause a denial of service (out-of-bounds
 access and guest instance crash) by leveraging use of qemu_map_ram_ptr to
 access guest ram block area (bsc#1048920).
- CVE-2017-11434: The dhcp_decode function in slirp/bootp.c allowed local guest
 OS users to cause a denial of service (out-of-bounds read) via a crafted DHCP
 options string (bsc#1049578).
- CVE-2017-10664: qemu-nbd did not ignore SIGPIPE, which allowed remote
 attackers to cause a denial of service (daemon crash) by disconnecting during
 a server-to-client reply attempt (bsc#1046637).");
