NVD Description

Note: Versions mentioned in the description apply only to the upstream abrt-addon-coredump-helper package and not the abrt-addon-coredump-helper package as distributed by AlmaLinux. See How to fix? for AlmaLinux: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.
