Threats Tagged 'cve-2026-54229'

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) 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.

A time-of-check time-of-use (TOCTOU) race condition was found in the abrt-dbus D-Bus service's SetElement method. Between dump directory creation and post-create event execution, any local user can call SetElement to write arbitrary text files into the root-owned dump directory, bypassing package validation and allowing crashes of unpackaged binaries to survive post-create processing.

A race condition was found in the abrt-dbus D-Bus service's ChownProblemDir method. ChownProblemDir opens the dump directory with DD_OPEN_READONLY and calls dd_chown to change ownership of all files to the caller's uid, succeeding even while post-create event handlers hold a write lock. This allows an attacker to gain filesystem-level control of the dump directory while privileged event scripts are still running.
