security advisorybug fixcritical bugRed Hat Enterprise Linux: RHSA-2020-5607-01 Critical Boot Issue Fix
An update for fapolicyd is now available for Red Hat Enterprise Linux 8. 2. Relevant releases/architectures: Red Hat Enterprise Linux AppStream (v. 8) - aarch64, noarch, ppc64le, s390x, x86_64 3. Description:. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: fapolicyd bug fix update Advisory ID: RHSA-2020:5607-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2020:5607 Issue date: 2020-12-17 ==================================================================== 1. Summary: An update for fapolicyd is now available for Red Hat Enterprise Linux 8. 2. Relevant releases/architectures: Red Hat Enterprise Linux AppStream (v. 8) - aarch64, noarch, ppc64le, s390x, x86_64 3. Description: The fapolicyd software framework introduces a form of file access control based on a user-defined policy. The application file access control feature provides one of the most efficient ways to prevent running untrusted and possibly malicious applications on the system. Bug Fix(es): * 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#1906472) * Adding DISA STIG during OS installation causes 'ipa-server-install' to fail (BZ#1905895) Note: The issue from BZ#1906472 was previously addressed in erratum RHBA-2020:5242 linked to from the References section. Due to the high impact of theissue that can cause systems to become unable to boot, we are releasing the same fix again in a security erratum to ensure proper visibility to users who only install security updates. This fix has not been changed in any way since the original bug fix erratum. This erratum does not provide any security fixes. For more details about the issue, see the Knowledgebase article linked from the References section. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1905895 - Adding DISA STIG during OS installation causes 'ipa-server-install' to fail [rhel-8.3.0.z] 1906472 - Erratum RHBA-2020:4969 is of no help when upgrading partially RHEL 8.2 systems [rhel-8.3.0.z] 6.
