Summary
Security update for xen
Details

This update for xen fixes several issues.

These security issues were fixed:

  • blkif responses leaked backend stack data, which allowed unprivileged guest to obtain sensitive information from the host or other guests (XSA-216, bsc#1042863)
  • Page transfer might have allowed PV guest to elevate privilege (XSA-217, bsc#1042882)
  • Races in the grant table unmap code allowed for informations leaks and potentially privilege escalation (XSA-218, bsc#1042893)
  • 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)
  • Stale P2M mappings due to insufficient error checking allowed malicious guest to leak information or elevate privileges (XSA-222, bsc#1042931)
  • 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)
  • CVE-2017-8905: Xen a failsafe callback, which might have allowed PV guest OS users to execute arbitrary code on the host OS (XSA-215, bsc#1034845).
  • CVE-2017-9503: The MegaRAID SAS 8708EM2 Host Bus Adapter emulation support was vulnerable to a null pointer dereference issue which allowed a privileged user inside guest to crash the Qemu process on the host resulting in DoS (bsc#1043297)
  • CVE-2017-9374: Missing free of 's->ipacket', causes a host memory leak, allowing for DoS (bsc#1043074)
  • CVE-2017-8112: hw/scsi/vmw_pvscsi.c allowed local guest OS privileged users to cause a denial of service (infinite loop and CPU consumption) via the message ring page count (bsc#1036470)
  • Missing NULL pointer check in event channel poll allows guests to DoS the host (XSA-221, bsc#1042924)

These non-security issues were fixed:

  • bsc#1032148: Ensure that time doesn't goes backwards during live migration of HVM domU
  • bsc#1031460: Fixed DomU Live Migration
  • bsc#1014136: Fixed kdump SLES12-SP2
  • bsc#1026236: Equalized paravirtualized vs. fully virtualized migration speed
