CVE-2017-8308
https://notcve.org/view.php?id=CVE-2017-8308
In Avast Antivirus before v17, an unprivileged user (and thus malware or a virus) can mark an arbitrary process as Trusted from the perspective of the Avast product. This bypasses the Self-Defense feature of the product, opening a door to subsequent attack on many of its components. En Avast Antivirus anteriores a v17, un usuario no privilegiado puede marcar un proceso arbitrario como Trusted desde la perspectiva del producto Avast. Esto evita la característica de Self-Defense del producto, abriendo una puerta a un ataque posterior en muchos de sus componentes. • http://www.securityfocus.com/bid/98084 https://www.trustwave.com/Resources/Security-Advisories/Advisories/Multiple-Vulnerabilities-in-Avast-Antivirus/?fid=9201 • CWE-269: Improper Privilege Management •
