TITLE

Xen and QEMU of qemu-xen of qdisk PV Service disruption in disk backend (DoS) Vulnerabilities

DESCRIPTION

The qdisk PV disk backend in qemu-xen in Xen 4.2.x and 4.3.x before 4.3.1, and qemu 1.1 and other versions, allows local HVM guests to cause a denial of service (domain grant reference consumption) via unspecified vectors. Xen is an open source virtual machine monitor developed by the University of Cambridge. Xen 4.2.x, 4.3.x have errors related to mapping authorization references. A domain can be exploited to leak, and then another domain that shares the driver domain is denied service status. Xen is prone to a denial-of-service vulnerability. Successful exploits may allow an attacker to cause a denial-of-service condition. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201407-03 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - http://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: Xen: Multiple Vunlerabilities Date: July 16, 2014 Bugs: #440768, #484478, #486354, #497082, #497084, #497086, #499054, #499124, #500528, #500530, #500536, #501080, #501906, #505714, #509054, #513824 ID: 201407-03 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in Xen, the worst of which could lead to arbitrary code execution.
