CVE-2025-64333

Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Prior to versions 7.0.13 and 8.0.2, a large HTTP content type, when logged can cause a stack overflow crashing Suricata. This issue has been patched in versions 7.0.13 and 8.0.2. A workaround for this issue involves limiting stream.reassembly.depth to less then half the stack size. Increasing the process stack size makes it less likely the bug will trigger.

Summary		(es) Suricata es un motor IDS, IPS y NSM de red desarrollado por la OISF (Open Information Security Foundation) y la comunidad de Suricata. Versiones anteriores a las 7.0.13 y 8.0.2, un tipo de contenido HTTP grande, al ser registrado, puede causar un desbordamiento de pila provocando el bloqueo de Suricata. Este problema se ha corregido en las versiones 7.0.13 y 8.0.2. Una solución alternativa para este problema implica limitar stream.reassembly.depth a menos de la mitad del tamaño de la pila. Aumentar el tamaño de la pila del proceso hace menos probable que el error se desencadene.
