An update that solves 6 vulnerabilities and has 12 fixes is

now available.

 

Description:

 

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
