CVE-2026-54231
Full vulnerability record from the local CVENow database.
Description
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.

"value": "Se encontró una vulnerabilidad de inyección de contenido en los scripts del gestor de eventos post-creación de ABRT en libreport. El script de evento consulta el registro de systemd en busca de entradas de registro que coincidan con el proceso bloqueado y escribe los resultados en archivos en el directorio de volcado sin sanear los caracteres de control incrustados. Un usuario local puede inyectar contenido arbitrario en la salida del registro incrustando caracteres de nueva línea en los mensajes de syslog, controlando el contenido que root escribe en los archivos del directorio de volcado."
