  2. Pwn2Own - Wikipedia

    en.wikipedia.org/wiki/Pwn2Own

    Internet Explorer was a 32-bit version 8 installed on 64-bit Windows 7 Service Pack 1. Security researcher Stephen Fewer of Harmony Security was successful in exploiting IE. This was demonstrated just as with Safari. [ 34 ]

  3. Return-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Return-oriented_programming

    Only 16 of the 32 address bits are available for randomization, and 16 bits of address randomization can be defeated by brute force attack in minutes. 64-bit architectures are more robust, with 40 of the 64 bits available for randomization. Brute force attack for 40-bit randomization is possible, but is unlikely to go unnoticed.

  4. Brute-force attack - Wikipedia

    en.wikipedia.org/wiki/Brute-force_attack

    Breaking a symmetric 256-bit key by brute-force requires 2 128 times more computational power than a 128-bit key. One of the fastest supercomputers in 2019 has a speed of 100 petaFLOPS which could theoretically check 100 trillion (10 14 ) AES keys per second (assuming 1000 operations per check), but would still require 3.67×10 55 years to ...

    The issue has been given the Common Vulnerabilities and Exposures number CVE-2024-3094 and has been assigned a CVSS score of 10.0, the highest possible score. [ 5 ] While xz is commonly present in most Linux distributions , at the time of discovery the backdoored version had not yet been widely deployed to production systems, but was present in ...

  6. 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 ...

    Pentoo is also available as an overlay [7] for an existing Gentoo installation. It features packet injection patched Wi-Fi drivers, GPGPU cracking software, and many tools for penetration testing and security assessment.

  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 ...
