Descriptions

Symantec Raptor Firewall 6.5 and 6.5.3, Enterprise Firewall 6.5.2 and 7.0, VelociRaptor Models 500/700/1000 and 1100/1200/1300, and Gateway Security 5110/5200/5300 generate easily predictable initial sequence numbers (ISN), which allows remote attackers to spoof connections.

Symantec Raptor Firewall 6.5 y 6.5.3, Enterprise Firewall 6.5.2 y 7.0, VelociRaptor modelos 500/700/1000 y 1100/1200/1300, y Gateway Security 5110/5200/5300 generan secuencias numéricas iniciales (ISN) fácilmente predecibles, lo que permitiría a atacantes remotos falsear conexiones.
