Descriptions

The compress_add_dlabel_points function in dns/Compress.c in MaraDNS 1.4.03, 1.4.05, and probably other versions allows remote attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a long DNS hostname with a large number of labels, which triggers a heap-based buffer overflow.

La función compress_add_dlabel_points en dns/Compress.c de MaraDNS v1.4.03, v1.4.05 y puede que otras versiones, permite a atacantes remotos provocar una denegación de servicio (fallo de segmentación) y posibilidad de ejecutar código de su elección a través de un nombre de DNS largo con un largo número de etiquetas, esto provoca un desbordamiento de búfer basado en memoria dinámica.
