Description

Security update for xen 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
