Additionally, guest domains could gain information about other virtual machines running on the same host or read arbitrary files on the host. Workaround : The CVEs listed below do not currently have fixes, but only apply to Xen setups which have “tmem” specified on the hypervisor command line. TMEM is not currently supported for use in production systems, and administrators using tmem should disable it.

This causes the domain 0 VCPU which tears down the domain to be blocked in the destroy hypercall. This causes that domain 0 VCPU to become unavailable and may cause the domain 0 kernel to panic. There is no requirement for memory sharing to be in use.

The Common Vulnerabilities and Exposures project identifies the following issues : - CVE-2012-3432 Guest mode unprivileged code, which has been granted the privilege to access MMIO regions, may leverage that access to crash the whole guest. Since this can be used to crash a client from within, this vulnerability is considered to have low impact. - CVE-2012-3433 A guest kernel can cause the host to become unresponsive for a period of time, potentially leading to a DoS. Since an attacker with full control in the guest can impact the host, this vulnerability is considered to have high impact. last seen 2020-03-17 modified 2012-08-20 plugin id 61578 published 2012-08-20 reporter This script is Copyright (C) 2012-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/61578 title Debian DSA-2531-1 : xen - Denial of Service NASL family OracleVM Local Security Checks NASL id ORACLEVM_OVMSA-2012-0035.NASL description The remote OracleVM system is missing necessary patches to address critical security updates : - Xen Security Advisory CVE-2012-3433 / XSA-11 HVM guest destroy p2m teardown host DoS vulnerability An HVM guest is able to manipulate its physical address space such that tearing down the guest takes an extended period amount of time searching for shared pages. This causes the domain 0 VCPU which tears down the domain to be blocked in the destroy hypercall. This causes that domain 0 VCPU to become unavailable and may cause the domain 0 kernel to panic. There is no requirement for memory sharing to be in use. From the patch description: xen: only check for shared pages while any exist on teardown Avoids worst case behavour when guest has a large p2m.
