US-CERT Warns of Crypto Bugs in IEEE Standard

Recent academic work focused on weak cryptographic protections in the implementation of the IEEE P1735 standard has been escalated to an alert published Friday by the Department of Homeland Security. DHS’ US-CERT warned the IEEE P1735 standard for encrypting electronic-design intellectual propert...

IEEE P1735 implementations may have weak cryptographic protections

Overview The P1735 IEEE standard describes methods for encrypting electronic-design intellectual property IP, as well as the management of access rights for such IP. The methods are flawed and, in the most egregious cases, enable attack vectors that allow recovery of the entire underlying plainte...

OracleVM 3.2 : xen (OVMSA-2017-0159)

The remote OracleVM system is missing necessary patches to address critical security updates : - The code of OVM3.2.9 is quite old, there is no getpage/putpage pair to protect the ownership and references of page table page which is mapped in emulatemapdest. This patch fix it by adding getpage in...

Xen Hypervisor Pagetable De-typing Recursion Handling Guest-to-Host DoS (XSA-240)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by a stack overflow vulnerability that is triggered when recursion is not properly handled when de-typing linear pagetables. By stacking multiple layers of page tables, an attacker within a...

UBUNTU-CVE-2017-15592

An issue was discovered in Xen through 4.9.x allowing x86 HVM guest OS users to cause a denial of service hypervisor crash or possibly gain privileges because self-linear shadow mappings are mishandled for translated guests...

x86: Incorrect handling of IST settings during CPU hotplug

ISSUE DESCRIPTION The x86-64 architecture allows interrupts to be run on distinct stacks. The choice of stack is encoded in a field of the corresponding interrupt descriptor in the Interrupt Descriptor Table IDT. That field selects an entry from the active Task State Segment TSS. Since, on AMD...

x86: Incorrect handling of self-linear shadow mappings with translated guests

ISSUE DESCRIPTION The shadow pagetable code uses linear mappings to inspect and modify the shadow pagetables. A linear mapping which points back to itself is known as self-linear. For translated guests, the shadow linear mappings being in a separate address space are not intended to be self-linea...
