Descriptions
In versions of FreeBSD 14.0-RELEASE before 14-RELEASE-p2, FreeBSD 13.2-RELEASE before 13.2-RELEASE-p7 and FreeBSD 12.4-RELEASE before 12.4-RELEASE-p9, the pf(4) packet filter incorrectly validates TCP sequence numbers. This could allow a malicious actor to execute a denial-of-service attack against hosts behind the firewall.
En las versiones de FreeBSD 14.0-RELEASE anteriores a 14-RELEASE-p2, FreeBSD 13.2-RELEASE anteriores a 13.2-RELEASE-p7 y FreeBSD 12.4-RELEASE anteriores a 12.4-RELEASE-p9, el filtro de paquetes pf(4) valida incorrectamente los números de secuencia TCP. Esto podría permitir que un actor malintencionado ejecute un ataque de denegación de servicio contra hosts detrás del firewall.
