Descriptions
The ip_expire function in net/ipv4/ip_fragment.c in the Linux kernel before 2.6.39 does not properly construct ICMP_TIME_EXCEEDED packets after a timeout, which allows remote attackers to cause a denial of service (invalid pointer dereference) via crafted fragmented packets.
La función ip_expire de net/ipv4/ip_fragment.c del kernel de Linux en versiones anteriores a la 2.6.39 no construye apropiadamente paquetes ICMP_TIME_EXCEEDED después de un timeout. Lo que permite a atacantes remotos provocar una denegación de servicio (resolución de puntero inválido) a través de paquetes fragmentados modificados.
