CVE-2025-64332

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 stack overflow that causes Suricata to crash can occur if SWF decompression is enabled. This issue has been patched in versions 7.0.13 and 8.0.2. A workaround for this issue involves disabling SWF decompression (swf-decompression in suricata.yaml), it is disabled by default; set decompress-depth to lower than half your stack size if swf-decompression must be enabled.

Summary		(es) Suricata es un motor de IDS, IPS y NSM de red desarrollado por la OISF (Open Information Security Foundation) y la comunidad de Suricata. Versiones anteriores a la 7.0.13 y 8.0.2, puede ocurrir un desbordamiento de pila que provoca el bloqueo de Suricata si la descompresión SWF está habilitada. Este problema se ha corregido en las versiones 7.0.13 y 8.0.2. Una solución alternativa para este problema implica deshabilitar la descompresión SWF (swf-decompression en suricata.yaml), está deshabilitada por defecto; establezca decompress-depth a menos de la mitad del tamaño de su pila si la descompresión SWF debe estar habilitada.
