CVE-2021-45339

Name of the Vulnerable Software and Affected Versions: Avast Antivirus versions prior to 20.4

Description: A privilege escalation issue allows a local user to gain elevated privileges by "hollowing" a trusted process, potentially leading to the bypassing of Avast self-defense.

Recommendations: For Avast Antivirus versions prior to 20.4, update to version 20.4 or later to resolve the issue. As a temporary workaround, consider restricting access to trusted processes to minimize the risk of exploitation.
