Importance of Logs and Log Management for IT Security

IT Security is the name of the game and no matter how big or small the size of your organization, you will always invest enough on securing certain aspects of your IT network. In many organizations, it starts with monitoring your network for vulnerabilities that may enter the network to access...

Debian Security Advisory DSA 2582-1 (xen - several vulnerabilities)

Multiple denial of service vulnerabilities have been discovered in the Xen Hypervisor. One of the issue CVE-2012-5513 could even lead to privilege escalation from guest to host. Some of the recently published Xen Security Advisories XSA 25 and 28 are not fixed by this update and should be fixed i...

CVE-2013-4329

The xenlight library libxl in Xen 4.0.x through 4.2.x, when IOMMU is disabled, provides access to a busmastering-capable PCI passthrough device before the IOMMU setup is complete, which allows local HVM guest domains to gain privileges or cause a denial of service via a DMA instruction...

CVE-2013-4329

The CVE affects the Xen hypervisor, specifically the xenlight library (libxl) used by the Xen toolstack. In Xen 4.0.x–4.2.x, when IOMMU is disabled, a busmastering PCI passthrough device can be accessed before IOMMU initialization completes, allowing local HVM guests to gain privileges or cause a...

PCI DSS 3.0 puts emphasis on year-round awareness

Its easy to think of PCI compliance as just another annual hoop to jump through. Of course, after the annual audit, the business is safe for another 12 months, right? Well, not exactly, and with the upcoming release of PCI DSS 3.0, there will be an even bigger reason to think about compliance...

libxl partially sets up HVM passthrough even with disabled iommu

ISSUE DESCRIPTION With HVM domains, libxl's setup of PCI passthrough devices does the IOMMU setup after giving via the device model the guest access to the hardware and advertising it to the guest. If the IOMMU is disabled the overall setup fails, but after the device has been made available to t...

CVE-2013-3495

The Intel VT-d Interrupt Remapping engine in Xen 3.3.x through 4.3.x allows local guests to cause a denial of service kernel panic via a malformed Message Signaled Interrupt MSI from a PCI device that is bus mastering capable that triggers a System Error Reporting SERR Non-Maskable Interrupt NMI...

CVE-2013-3495

CVE-2013-3495 affects the Intel VT-d Interrupt Remapping engine in Xen 3.3.x through 4.3.x. The vulnerability allows a local guest to cause a denial of service (kernel panic) by sending a malformed Message Signaled Interrupt (MSI) from a bus-master PCI device, triggering a System Error Reporting ...

Intel VT-d Interrupt Remapping engines can be evaded by native NMI interrupts

ISSUE DESCRIPTION Message Signaled Interrupts MSI interrupts on Intel platforms are defined as DWORD writes to a special address location 0xFEE?????. MSIs on Intel Platforms supporting VT-d have two defined formats - Remappable format interrupts, and Compatibility not remappable format interrupts...
