RHEL 8 : abrt (RHSA-2026:54272)

high Nessus Plugin ID 334918

Synopsis

The remote Red Hat host is missing one or more security updates for abrt.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:54272 advisory.

The Automatic Bug Reporting Tool (ABRT) recognizes defects in applications and creates bug reports that help maintainers fix the defects. ABRT uses a plug-in system to extend its functionality.

Security Fix(es):

* abrt: TOCTOU race condition in abrt-dbus SetElement allows arbitrary file writes to dump directories (CVE-2026-54228)

* abrt: ChownProblemDir succeeds during active post-create event processing due to inadequate locking (CVE-2026-54229)

* abrt: event handler scripts follow symlinks when writing output files, allowing arbitrary file overwrites (CVE-2026-54230)

* abrt: unsanitized systemd journal content written to dump directory files enables content injection (CVE-2026-54231)

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL abrt package based on the guidance in RHSA-2026:54272.
