-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2020.4459 fapolicyd bug fix update 18 December 2020 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: fapolicyd Publisher: Red Hat Operating System: Red Hat Impact/Access: Denial of Service -- Existing Account Resolution: Patch/Upgrade Original Bulletin: https://access.redhat.com/errata/RHSA-2020:5609 https://access.redhat.com/errata/RHSA-2020:5608 https://access.redhat.com/errata/RHSA-2020:5607 Comment: This bulletin contains three (3) Red Hat security advisories. - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ===================================================================== Red Hat Security Advisory Synopsis: Important: fapolicyd bug fix update Advisory ID: RHSA-2020:5609-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2020:5609 Issue date: 2020-12-17 ===================================================================== 1. Summary: An update for fapolicyd is now available for Red Hat Enterprise Linux 8.1 Extended Update Support. 2. Relevant releases/architectures: Red Hat Enterprise Linux AppStream EUS (v. 8.1) - aarch64, 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: * 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#1906474) Note: The issue from BZ#1906474 was previously addressed in erratum RHBA-2020:5241 linked to from the References section. Due to the high impact of the issue 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.
