-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: systemd security update Advisory ID: RHSA-2021:3900-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:3900 Issue date: 2021-10-19 CVE Names: CVE-2019-3842 CVE-2020-13776 ==================================================================== 1. Summary: An update for systemd is now available for Red Hat Enterprise Linux 8.2 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux BaseOS EUS (v. 8.2) - aarch64, ppc64le, s390x, x86_64 3. Description: The systemd packages contain systemd, a system and service manager for Linux, compatible with the SysV and LSB init scripts. It provides aggressive parallelism capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, and keeps track of processes using Linux cgroups. In addition, it supports snapshotting and restoring of the system state, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. It can also work as a drop-in replacement for sysvinit. Security Fix(es): * systemd: Spoofing of XDG_SEAT allows for actions to be checked against "allow_active" instead of "allow_any" (CVE-2019-3842) * systemd: Mishandles numerical usernames beginning with decimal digits or 0x followed by hexadecimal digits (CVE-2020-13776) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in 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/): 1668521 - CVE-2019-3842 systemd: Spoofing of XDG_SEAT allows for actions to be checked against "allow_active" instead of "allow_any" 1845534 - CVE-2020-13776 systemd: Mishandles numerical usernames beginning with decimal digits or 0x followed by hexadecimal digits 6.
