NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-abrt-doc package and not the python3-abrt-doc package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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.
