CVE-2020-25533

Name of the Vulnerable Software and Affected Versions: Malwarebytes versions prior to 4.0

Description: An issue was discovered in Malwarebytes where a malicious application could perform a privileged action within the Malwarebytes launch daemon. The privileged service improperly validated XPC connections by relying on the PID instead of the audit token. An attacker can construct a situation where the same PID is used for running two different programs at different times, by leveraging a race condition during crafted use of posix spawn.

Recommendations: For versions prior to 4.0, update to version 4.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the Malwarebytes launch daemon to minimize the risk of exploitation.
