Descriptions
Integer overflow in the rsCStrExtendBuf function in runtime/stringbuf.c in the imfile module in rsyslog 4.x before 4.6.6, 5.x before 5.7.4, and 6.x before 6.1.4 allows local users to cause a denial of service (daemon hang) via a large file, which triggers a heap-based buffer overflow.
Desbordamiento de entero en la función rsCStrExtendBuf en runtime/stringbuf.c en el módulo imfile en rsyslog v4.x anteriores v4.6.6, v5.x anteriores a v5.7.4, y v6.x anteriores a v6.1.4, permite a atacantes remotos provocar una denegación de servicio (cuelgue del demonio) a través de un fichero grande, que provoca un desbordamiento de búfer basado en memoria dinámica.
