Topic

An update for fapolicyd is now available for Red Hat Enterprise Linux 8.2 Extended Update Support.

Description

The fapolicyd software framework introduces a form of application whitelisting
and blacklisting based on a user-defined policy. The application whitelisting
feature provides one of the most efficient ways to prevent running untrusted and possibly malicious applications on the system.

Bug Fix:

  • When an update replaces the binary of a running application, the kernel modifies the application binary path in memory by appending the " (deleted)" suffix. Previously, the fapolicyd file access policy daemon treated such

applications as untrusted, and prevented them from opening and executing any other files. As a consequence, the system was sometimes unable to boot after applying updates.

With this update, fapolicyd ignores the suffix in the binary path so the binary can match the trust database. As a result, fapolicyd enforces the rules correctly and the update process can finish.

(BZ#1897091)

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
