Descriptions
It was found that the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation before 2.6.22.17 used the IPv4-only inet_sk_rebuild_header() function for both IPv4 and IPv6 DCCP connections, which could result in memory corruptions. A remote attacker could use this flaw to crash the system.
Se ha encontrado que la implementación del Protocolo de Control de Congestión de Datagramas (DCCP) del kernel de Linux en versiones anteriores a la 2.6.22.17 usaba la función inet_sk_rebuild_header() solo para IPv4 y conexiones DCCP IPv6, lo que podría resultar en corrupciones de memoria. Un atacante remoto podría utilizar este fallo para provocar un cierre inesperado del sistema.
