  2. Virtual machine escape - Wikipedia

    en.wikipedia.org/wiki/Virtual_machine_escape

    CVE-2016-6258 Xen Hypervisor: The PV pagetable code has fast-paths for making updates to pre-existing pagetable entries, to skip expensive re-validation in safe cases (e.g. clearing only Access/Dirty bits). The bits considered safe were too broad, and not actually safe. CVE-2016-7092 Xen Hypervisor: Disallow L3 recursive pagetable for 32-bit PV ...

  3. Active Scripting - Wikipedia

    en.wikipedia.org/wiki/Active_Scripting

    Clicking on an icon or running from the command line, a script, the Run dialogue, etc. will by default run a plain text file containing the code. A Windows Script File (.wsf) is an XML file that can contain more than one script in more than one language in addition to other elements, and are executed by the Windows Script Host.

  4. Sandbox (computer security) - Wikipedia

    en.wikipedia.org/wiki/Sandbox_(computer_security)

    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-world damage. [1] It is often used to kill untested or untrusted programs or code, possibly from unverified or untrusted third parties, suppliers, users or websites, without risking harm to ...

  5. Sandbox (software development) - Wikipedia

    en.wikipedia.org/wiki/Sandbox_(software_development)

    The term sandbox is commonly used for the development of web services to refer to a mirrored production environment for use by external developers. Typically, a third-party developer will develop and create an application that will use a web service from the sandbox, which is used to allow a third-party team to validate their code before migrating it to the production environment.

  6. Unreachable code - Wikipedia

    en.wikipedia.org/wiki/Unreachable_code

    In computer programming, unreachable code is part of the source code of a program which can never be executed because there exists no control flow path to the code from the rest of the program. [ 1 ] Unreachable code is sometimes also called dead code , [ 2 ] [ 3 ] although dead code may also refer to code that is executed but has no effect on ...

  7. Trusted execution environment - Wikipedia

    en.wikipedia.org/wiki/Trusted_execution_environment

    [1] [2] [3] A TEE as an isolated execution environment provides security features such as isolated execution, integrity of applications executing with the TEE, and confidentiality of their assets. In general terms, the TEE offers an execution space that provides a higher level of security for trusted applications running on the device than a ...

  8. Just-in-time compilation - Wikipedia

    en.wikipedia.org/wiki/Just-in-time_compilation

    The application code is initially interpreted, but the JVM monitors which sequences of bytecode are frequently executed and translates them to machine code for direct execution on the hardware. For bytecode which is executed only a few times, this saves the compilation time and reduces the initial latency; for frequently executed bytecode, JIT ...

  9. Address space layout randomization - Wikipedia

    en.wikipedia.org/wiki/Address_space_layout...

    Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. [1] In order to prevent an attacker from reliably redirecting code execution to, for example, a particular exploited function in memory, ASLR randomly arranges the address space positions of key data areas of a process, including the base of the ...
