Design/Logic Flaw

Xen 4.2.x and 4.1.x does not properly restrict access to IRQs, which allows local stub domain clients to gain access to IRQs and cause a denial of service via vectors related to "passed-through IRQs or PCI devices."...

CVE-2013-1919

The CVE-2013-1919 issue affects Xen 4.1.x and 4.2.x where access to IRQs could be inappropriately restricted, enabling local stub domain clients to access IRQs and cause a denial of service via passed-through IRQs or PCI devices. Public descriptions frame this as a local-denial of-service conditi...

PCI DSS 3.0 Is Coming Soon

The PCI Security Standards Council SSC plans on releasing the newest version of the PCI Data Security Standard in October, 2013. Predictably, the PCI SSC has been tight-lipped on divulging details regarding any expected changes...

VT-d interrupt remapping source validation flaw for bridges

ISSUE DESCRIPTION Interrupt remapping table entries for MSI interrupts set up by bridge devices did not get any source validation set up on them, allowing misbehaving or malicious guests to inject interrupts into the domain owning the bridges. In a typical Xen system bridge devices are owned by...

The PCI DSS Cloud Computing Guidelines: An Executive Summary

The PCI SSC and its Cloud Special Interest Group has released its Cloud Computing Guidelines after a year of collaboration and input from SIG members. Coalfire was a big contributor to this document, and we think it is required reading for anyone who has front-line responsibility for managing...

Several access permission issues with IRQs for unprivileged guests

ISSUE DESCRIPTION Various IRQ related access control operations may not have the intended effect, thus potentially permitting a stub domain to grant its client domain access to an IRQ it doesn't have access to itself. IMPACT Malicious or buggy stub domains kernels can mount a denial of service...

Scientific Linux Security Update : kernel on SL5.x i386/x86_64 (20130416)

This update fixes the following security issues : - A flaw was found in the Xen netback driver implementation in the Linux kernel. A privileged guest user with access to a para-virtualized network device could use this flaw to cause a long loop in netback, leading to a denial of service that coul...
