Descriptions

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-2018-0762, CVE-2018-0768, CVE-2018-0769, CVE-2018-0770, CVE-2018-0772, CVE-2018-0773, CVE-2018-0774, CVE-2018-0775, CVE-2018-0776, CVE-2018-0777, CVE-2018-0778, and CVE-2018-0781.

Microsoft Edge en Windows 10 Gold, 1511, 1607, 1703 y 1709 y Windows Server 2016 permite que un atacante ejecute código arbitrario en el contexto del usuario actual debido a la forma en la que el motor de scripting manipula objetos en la memoria. Esto también se conoce como "Scripting Engine Memory Corruption Vulnerability". El ID de este CVE es diferente de CVE-2018-0762, CVE-2018-0768, CVE-2018-0769, CVE-2018-0770, CVE-2018-0772, 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 the generation of JIT code for functions that perform string concatenations. By performing actions in JavaScript, an attacker 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.

Microsoft Edge Chakra JIT suffers from a missing integer overflow check in Lowerer::LowerSetConcatStrMultiItem.
