Descriptions
ChakraCore and Internet Explorer in Microsoft Windows 7 SP1, Windows Server 2008 and R2 SP1, Windows 8.1 and Windows RT 8.1, Windows Server 2012 and R2, and Microsoft Edge and Internet Explorer in Windows 10 Gold, 1511, 1607, 1703, 1709, Windows Server 2016 and Windows Server, version 1709 allows an attacker to gain the same user rights as the current user, due to how Microsoft browsers handle objects in memory, aka "Scripting Engine Memory Corruption Vulnerability". This CVE ID is unique from CVE-2017-11836, CVE-2017-11837, CVE-2017-11838, CVE-2017-11839, CVE-2017-11840, CVE-2017-11841, CVE-2017-11843, CVE-2017-11846, CVE-2017-11859, CVE-2017-11861, CVE-2017-11862, CVE-2017-11866, CVE-2017-11869, CVE-2017-11870, CVE-2017-11871, and CVE-2017-11873.
ChakraCore e Internet Explorer en Microsoft Windows 7 SP1, Windows Server 2008 y R2 SP1, Windows 8.1 y Windows RT 8.1, Windows Server 2012 y R2; y Microsoft Edge e Internet Explorer en Windows 10 Gold, 1511, 1607, 1703, 1709, Windows Server 2016 y Windows Server 1709 permiten que un atacante obtenga los mismos derechos de usuario que el usuario actual, debido a la forma en la que los navegadores de Microsoft gestionan los objetos en la memoria. Esto también se conoce como "Scripting Engine Memory Corruption Vulnerability". El ID de este CVE es diferente de CVE-2017-11836, CVE-2017-11837, CVE-2017-11838, CVE-2017-11839, CVE-2017-11840, CVE-2017-11841, CVE-2017-11843, CVE-2017-11846, CVE-2017-11859, CVE-2017-11861, CVE-2017-11862, CVE-2017-11866, CVE-2017-11869, CVE-2017-11870, CVE-2017-11871 y CVE-2017-11873.
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Chakra. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the processing of regular expressions. A crafted regular expression can trigger an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code under the context of the current process.
