[HIGH] Wormable Flaw, 0days Lead Sept. 2022 Patch Tuesday
This month’s Patch Tuesday offers a little something for everyone, including security updates for a zero-day flaw in Microsoft Windows that is under active attack, and another Windows weakness experts say could be used to power a fast-spreading computer worm. Also, Apple has also quashed a pair of zero-day bugs affecting certain macOS and iOS users, and released iOS 16 , which offers a new privacy and security feature called “ Lockdown Mode .” And Adobe axed 63 vulnerabilities in a range of products.
Microsoft today released software patches to plug at least 64 security holes in Windows and related products. Worst in terms of outright scariness is CVE-2022-37969 , which is a “privilege escalation” weakness in the Windows Common Log File System Driver that allows attackers to gain SYSTEM-l

## Microsoft Patch Tuesday for September 2022 — Snort rules and prominent vulnerabilities
Microsoft released its monthly security update Tuesday, disclosing 64 vulnerabilities across the company’s hardware and software line, a sharp decline from the record number of issues Microsoft disclosed last month.
September's security update features five critical vulnerabilities, 10 fewer than were included in last month’s Patch Tuesday. There are two moderate-severity vulnerabilities in this release and a low-security issue that’s already been patched as a part of a recent Google Chromium update. The remainder is considered “important.”
The most serious vulnerability exists in several versions of Windows Server and Windows 10 that could allow an attacker to gain the ability to execute remote co
