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)

fkie_cve-2026-54231

A content injection vulnerability was found in the ABRT post-create event handler scripts in libreport. The event script queries the systemd journal for log entries matching the crashed process and writes the results to files in the dump directory without sanitizing embedded control characters. A local user can inject arbitrary content into the journal output by embedding newline characters in syslog messages, controlling the content that root writes to dump directory files.
