These security issues were fixed:
- CVE-2017-10912: Page transfer might have allowed PV guest to elevate
privilege (XSA-217, bsc#1042882)
- CVE-2017-10913 CVE-2017-10914: Races in the grant table unmap code
allowed for information leaks and potentially privilege escalation
(XSA-218, bsc#1042893)
- CVE-2017-10915: Insufficient reference counts during shadow emulation
allowed a malicious pair of guest to elevate their privileges to the
privileges that XEN runs under (XSA-219, bsc#1042915)
- CVE-2017-10917: Missing NULL pointer check in event channel poll allows
guests to DoS the host (XSA-221, bsc#1042924)
- CVE-2017-10918: Stale P2M mappings due to insufficient error checking
allowed malicious guest to leak information or elevate privileges
(XSA-222, bsc#1042931)
- CVE-2017-10920, CVE-2017-10921, CVE-2017-10922: Grant table operations
mishandled reference counts allowing malicious guests to escape
(XSA-224, bsc#1042938)
- CVE-2017-9330: USB OHCI Emulation in qemu allowed local guest OS users
to cause a denial of service (infinite loop) by leveraging an incorrect
return value (bsc#1042160)
- CVE-2017-8309: Memory leak in the audio/audio.c allowed remote attackers
to cause a denial of service (memory consumption) by repeatedly starting
and stopping audio capture (bsc#1037243)
- PKRU and BND* leakage between vCPU-s might have leaked information to
other guests (XSA-220, bsc#1042923)
These non-security issues were fixed:
- bsc#1027519: Included various upstream patches
- bsc#1035642: Ensure that rpmbuild works
