This update for xen fixes several issues.

 

These security issues were fixed:

unprivileged guest to obtain sensitive information from the host or

other guests (XSA-216, bsc#1042863)

- 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 informations 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-2017-10922, CVE-2017-10921, CVE-2017-10920: Grant table operations

mishandled reference counts allowing malicious guests to escape

(XSA-224, bsc#1042938)

- CVE-2017-10916: PKRU and BND* leakage between vCPU-s might have leaked

information to other guests (XSA-220, bsc#1042923)

- 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-2017-8112: 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)

- 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)

 

These non-security issues were fixed:

 

- bsc#1031460: Fixed DomU Live Migration

- bsc#1014136: Fixed kdump SLES12-SP2

- bsc#1026236: Equalized paravirtualized vs. fully virtualized migration
