  2. Heap spraying - Wikipedia

    en.wikipedia.org/wiki/Heap_spraying

    Heap sprays take advantage of the fact that on most architectures and operating systems, the start location of large heap allocations is predictable and consecutive allocations are roughly sequential. This means that the sprayed heap will roughly be in the same location each and every time the heap spray is run.

  3. Transient execution CPU vulnerability - Wikipedia

    en.wikipedia.org/wiki/Transient_execution_CPU...

    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.

  4. Meltdown (security vulnerability) - Wikipedia

    en.wikipedia.org/wiki/Meltdown_(security...

    Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...

    Use a function call with a different number of arguments than the call is designed for, causing a stack misalignment, and code execution after the function returns (patched in Windows 10). [ 27 ] Use a function call with the same number of arguments, but one of pointers passed is treated as an object and writes to a pointer-based offset ...

  6. Time travel debugging - Wikipedia

    en.wikipedia.org/wiki/Time_travel_debugging

    Time travel debugging or time traveling debugging is the process of stepping back in time through source code to understand what is happening during execution of a computer program. [1] Typically, debugging and debuggers , tools that assist a user with the process of debugging, allow users to pause the execution of running software and inspect ...

  7. Spectre (security vulnerability) - Wikipedia

    en.wikipedia.org/wiki/Spectre_(security...

    [4] At the same time, according to Dell: "No 'real-world' exploits of these vulnerabilities [i.e., Meltdown and Spectre] have been reported to date [7 February 2018], though researchers have produced proof-of-concepts." [77] [78] Several procedures to help protect home computers and related devices from the vulnerability have been published.

  8. Speculative execution - Wikipedia

    en.wikipedia.org/wiki/Speculative_execution

    Predictive execution is a form of speculative execution where some outcome is predicted and execution proceeds along the predicted path until the actual result is known. If the prediction is true, the predicted execution is allowed to commit; however, if there is a misprediction, execution has to be unrolled and re-executed.
