https://notcve.org/view.php?id=CVE-2019-11230
18 Jul 2019 — In Avast Antivirus before 19.4, a local administrator can trick the product into renaming arbitrary files by replacing the Logs\Update.log file with a symlink. The next time the product attempts to write to the log file, the target of the symlink is renamed. This defect can be exploited to rename a critical product file (e.g., AvastSvc.exe), causing the product to fail to start on the next system restart. En Avast Antivirus antes de 19.4, un administrador local puede engañar al producto para que cambie el n... • http://www.mcerlane.co.uk/CVE-2019-11230 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
