CVE-2025-59148

Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Versions 8.0.0 and below incorrectly handle the entropy keyword when not anchored to a "sticky" buffer, which can lead to a segmentation fault. This issue is fixed in version 8.0.1. To workaround this issue, users can disable rules using the entropy keyword, or validate they are anchored to a sticky buffer.

Summary		(es) Suricata es un motor de red IDS, IPS y NSM desarrollado por la OISF (Open Information Security Foundation) y la comunidad de Suricata. Las versiones 8.0.0 e inferiores manejan incorrectamente la palabra clave entropy cuando no está anclada a un búfer 'sticky', lo que puede provocar un fallo de segmentación. Este problema está solucionado en la versión 8.0.1. Como solución alternativa a este problema, los usuarios pueden deshabilitar las reglas que usan la palabra clave entropy, o validar que estén ancladas a un búfer 'sticky'.
