The Benefits of a Single Provider DNS Platform

I've written in previous blogs about the value of using DNS as a security control point and how using a DNS based security solution like Akamai's Enterprise Threat Protector can help accelerate your transition to a Zero Trust security approach. In this blog, I'm going to cover how in addition to...

CVE-2019-18421

An issue was discovered in Xen through 4.12.x allowing x86 PV guest OS users to gain host OS privileges by leveraging race conditions in pagetable promotion and demotion operations. There are issues with restartable PV type change operations. To avoid using shadow pagetables for PV guests, Xen...

Issues with restartable PV type change operations

ISSUE DESCRIPTION To avoid using shadow pagetables for PV guests, Xen exposes the actual hardware pagetables to the guest. In order to prevent the guest from modifying these page tables directly, Xen keeps track of how pages are used using a type system; pages must be "promoted" before being used...

Amazon Linux AMI : openssh (ALAS-2019-1313)

An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server or Man-in-The-Middle attacker can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This...
