Device quarantine for alternate pci assignment methods
ISSUE DESCRIPTION XSA-302 relies on the use of libxl's "assignable-add" feature to prepare devices to be assigned to untrusted guests. Unfortunately, this is not considered a strictly required step for device assignment. The PCI passthrough documentation on the wiki describes alternate ways of...

4 Best Free Online Security Tools for SMEs in 2020
Cyberattacks on small and midsized companies in 2019 cost $200,000 per company on average, mercilessly putting many of them out of business, says CNBC in its analysis of a recent Accenture report. In light of the global cybersecurity skills shortage, the number is set to soar in 2020. Solely in t...
Xen PCI Pass-Through Elevation of Privilege vulnerability (XSA-302)
According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by an elevation of privilege vulnerability due to a memory corruption that may occur after a passed through PCI device is deassigned from an untrusted domain. An unauthenticated attacker wit...

CVE-2019-18844
ACRN Device Model (pre-2019w25.5-140000p) is affected by a denial-of-service condition caused by using asserts in PCI core code (devicemodel/hw/pci/core.c and devicemodel/include/pci_core.h) to propagate errors/diagnostic information. The issue can trigger an assertion failure in the PCI core. Th...
