In theory, a virtual machine is a "completely isolated guest operating system installation within a normal host operating system", [2] but this isn't always the case in practice. For example, in 2008, a vulnerability (CVE-2008-0923) in VMware discovered by Core Security Technologies made VM escape possible on VMware Workstation 6.0.2 and 5.5.4.
Transient execution CPU vulnerabilities are vulnerabilities in which instructions, most often optimized using speculative execution, are executed temporarily by a microprocessor, without committing their results due to a misprediction or error, resulting in leaking secret data to an unauthorized party.
Hyperjacking is an attack in which a hacker takes malicious control over the hypervisor that creates the virtual environment within a virtual machine (VM) host. [1] The point of the attack is to target the operating system that is below that of the virtual machines so that the attacker's program can run and the applications on the VMs above it will be completely oblivious to its presence.
The update caused machines to either enter into a bootloop or boot into recovery mode. [15] [16] Almost immediately, Windows virtual machines on the Microsoft Azure cloud platform began rebooting and crashing, [17] and at 06:48 UTC, Google Compute Engine also reported the problem.
The Java software platform provides a number of features designed for improving the security of Java applications. This includes enforcing runtime constraints through the use of the Java Virtual Machine (JVM), a security manager that sandboxes untrusted code from the rest of the operating system, and a suite of security APIs that Java developers can utilise.
Foreshadow, known as L1 Terminal Fault (L1TF) by Intel, [1] [2] is a vulnerability that affects modern microprocessors that was first discovered by two independent teams of researchers in January 2018, but was first disclosed to the public on 14 August 2018. [18]
In computer security, a sandbox is a security mechanism for separating running programs, usually in an effort to mitigate system failures and/or software vulnerabilities from spreading. The sandbox metaphor derives from the concept of a child's sandbox—a play area where children can build, destroy, and experiment without causing any real ...
