HIGH Summary
The Microsoft (1) JScript 9, (2) VBScript, and (3) Chakra JavaScript engines, as used in Microsoft Internet Explorer 9 through 11, Microsoft Edge, and other products, allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka "Scripting Engine Memory Corruption Vulnerability," a different vulnerability than CVE-2016-3259.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

NASL family Windows : Microsoft Bulletins NASL id SMB_NT_MS16-084.NASL description The version of Internet Explorer installed on the remote host is missing Cumulative Security Update 3169991. It is, therefore, affected by multiple vulnerabilities, the majority of which are remote code execution vulnerabilities. An unauthenticated, remote attacker can exploit these issues by convincing a user to visit a specially crafted website, resulting in the execution of arbitrary code in the context of the current user. last seen 2020-06-01 modified 2020-06-02 plugin id 92015 published 2016-07-12 reporter This script is Copyright (C) 2016-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/92015 title MS16-084: Cumulative Security Update for Internet Explorer (3169991) NASL family Windows : Microsoft Bulletins NASL id SMB_NT_MS16-085.NASL description The version of Microsoft Edge installed on the remote Windows host is missing Cumulative Security Update 3169999. It is, therefore, affected by multiple vulnerabilities : - A security feature bypass vulnerability exists due to a failure to properly implement Address Space Layout Randomization (ASLR). An unauthenticated, remote attacker can exploit this, by convincing a user to visit a website that hosts crafted content, to bypass the ASLR security feature, resulting in the ability to predict memory offsets in a call stack. (CVE-2016-3244) - Multiple remote code execution vulnerabilities exist due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit these, via a crafted website or email, to corrupt memory, resulting in the execution of arbitrary code within the context of the current user. (CVE-2016-3246, CVE-2016-3264) - Multiple remote code execution vulnerabilities exist in the Chakra JavaScript engine due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit these, by convincing a user to visit a specially crafted website or open a specially crafted Microsoft Office document that hosts the Edge rendering engine, to corrupt memory, resulting in the execution of arbitrary code within the context of the current user. (CVE-2016-3248, CVE-2016-3259, CVE-2016-3260, CVE-2016-3265, CVE-2016-3269) - An information disclosure vulnerability exists in VBScript due to improper disclosure of the contents of its memory. An unauthenticated, remote attacker who has knowledge of the memory address where an object was created can exploit this issue to disclose potentially sensitive information. (CVE-2016-3271) - An information disclosure vulnerability exists in the Microsoft Browser XSS Filter due to improper validation of content. An unauthenticated, remote attacker can exploit this, via a website that hosts content with specially crafted JavaScript, to disclose potentially sensitive information. (CVE-2016-3273) - Multiple spoofing vulnerabilities exist due to improper parsing of HTTP or HTML content. An unauthenticated, remote attacker can exploit these to redirect a user to a malicious website having spoofed contents. (CVE-2016-3274, CVE-2016-3276) - An unspecified information disclosure vulnerability exists due to improper handling of objects in memory that allows an unauthenticated, remote attacker to disclose potentially sensitive information.
