Descriptions

Multiple stack consumption vulnerabilities in the kernel in NetBSD 4.0, 5.0 before 5.0.3, and 5.1 before 5.1.1, when IPsec is enabled, allow remote attackers to cause a denial of service (memory corruption and panic) or possibly have unspecified other impact via a crafted (1) IPv4 or (2) IPv6 packet with nested IPComp headers.

Multiples vulnerabilidades de consumos de pila en el Kernel de NetBSD v4.0, v5.0 con anterioridad a v5.0.3 y v5.1 con anterioridad a v5.1.1, IPsec cuando está activada, permite a atacantes remotos provocar una denegación de servicio ( corrupción de memoria y kernel panic ) o posiblemente tener un impacto no especificado a través de paquetes manipulados en ( 1 )IPv4 o ( 2 )IPv6 con cabeceras anidadas IPComp.
