Descriptions

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 Internet Explorer and Microsoft Edge in Windows 10 Gold, 1511, 1607, 1703, 1709, and Windows Server 2016 allows an attacker to execute arbitrary code in the context of the current user, due to how the scripting engine handles objects in memory, aka "Scripting Engine Memory Corruption Vulnerability". This CVE ID is unique from CVE-2018-0758, CVE-2018-0762, CVE-2018-0768, CVE-2018-0769, CVE-2018-0770, CVE-2018-0773, CVE-2018-0774, CVE-2018-0775, CVE-2018-0776, CVE-2018-0777, CVE-2018-0778, and CVE-2018-0781.

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 y Windows Server 2016 permite que un atacante ejecute código arbitrario en el contexto del usuario actual por la manera en la que el motor de scripting gestiona los objetos en la memoria. Esta vulnerabilidad también se conoce como "Scripting Engine Memory Corruption Vulnerability". El ID de este CVE es diferente de CVE-2018-0758, CVE-2018-0762, CVE-2018-0768, CVE-2018-0769, CVE-2018-0770, CVE-2018-0773, CVE-2018-0774, CVE-2018-0775, CVE-2018-0776, CVE-2018-0777, CVE-2018-0778 y CVE-2018-0781.

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 Chakra's memory allocation routines. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer and writing to memory. An attacker can leverage this vulnerability to execute code under the context of the current process.
