AVAST SecureLine 5.5.522.0 - 'SecureLine' Unquoted Service Path

Avast SecureLine 5.5.522.0 contains an unquoted service path vulnerability that allows local users to potentially execute code with elevated system privileges. Attackers can exploit the unquoted path in the service configuration to inject malicious code that would execute with LocalSystem account permissions during service startup.

The VPN service in AVAST SecureLine before 5.6.4982.470 allows local users to write to arbitrary files via an Object Manager symbolic link from the log directory (which has weak permissions).
