CVSS: 5.6EPSS: 97%CPEs: 1467EXPL: 3CVE-2017-5753 – Multiple CPUs - 'Spectre' Information Disclosure
https://notcve.org/view.php?id=CVE-2017-5753
Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. Los sistemas con microprocesadores con ejecución especulativa y predicción de ramas podrían permitir la revelación no autorizada de información al atacante con acceso de usuario local mediante un análisis de un canal lateral. An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. • https://www.exploit-db.com/exploits/43427 https://github.com/sachinthaBS/Spectre-Vulnerability-CVE-2017-5753- http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00016.html http://nvidia.custhe • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
