Analysis Summary
Microsoft has released November updates to fix 75 security flaws in multiple products.
CVE-2019-1429 – Scripting Engine Memory Corruption Vulnerability could allow an attacker to conduct a web-based attack via specially crafted web pages that exploits the vulnerability. In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website. An attacker could also embed an ActiveX control marked “safe for initialization” in an application or Microsoft Office document that hosts the IE rendering engine. 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.
Microsoft also fixed a publicly disclosed vulnerability in Microsoft Office for Mac titled “CVE-2019-1457 | Microsoft Office Excel Security Feature Bypass” that allows attackers to bypass security restrictions. If the Microsoft Excel for Mac option “Disable all macros without notification” is enabled, XLM macros in SYLK files are executed without prompting the user. “If Office for the Mac has been configured to use the “Disable all macros without notification” feature, XLM macros in SYLK files are executed without prompting the user. This behavior is consistent even with fully-patched Office 2016 and Office 2019 for Mac systems, says Will Dormann of the CERT/CC.
