An update that solves two vulnerabilities and has 9 fixes

is now available.

 

Description:

 

This update for xen fixes several issues.

 

These security issues were fixed:

 

- 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)

- Missing NULL pointer check in event channel poll allows guests to DoS

the host (XSA-221, bsc#1042924)

- 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)

- 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
