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 nombre de los archivos arbitrarios al reemplazar el archivo Logs \ Update.log con un enlace simbólico. La próxima vez que el producto intente escribir en el archivo de registro, se cambiará el nombre del destino del enlace simbólico. • http://www.mcerlane.co.uk/CVE-2019-11230 http://www.securityfocus.com/bid/109344 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
