SCA: security update for Microsoft.ChakraCore (GHSA-8xv4-c7rq-j577)

medium Tenable Cloud Security Plugin ID 431891

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A remote code execution vulnerability exists in the way that the Chakra scripting engine handles objects
 in memory in Microsoft Edge (HTML-based). The vulnerability could corrupt memory in such a way that an
 attacker could execute arbitrary code in the context of the current user. An attacker who successfully
 exploited the vulnerability could gain the same user rights as the current user. If the current user is
 logged on with administrative user rights, an attacker who successfully exploited the vulnerability could
 take control of an affected system. An attacker could then install programs; view, change, or delete data;
 or create new accounts with full user rights. In a web-based attack scenario, an attacker could host a
 specially crafted website that is designed to exploit the vulnerability through Microsoft Edge (HTML-
 based) and then convince a user to view the website. The attacker could also take advantage of compromised
 websites and websites that accept or host user-provided content or advertisements. These websites could
 contain specially crafted content that could exploit the vulnerability. The security update addresses the
 vulnerability by modifying how the Chakra scripting engine handles objects in memory. (CVE-2020-1037)
