Descriptions

The OSPFv3 implementation in ospf6d in Quagga before 0.99.19 allows remote attackers to cause a denial of service (out-of-bounds memory access and daemon crash) via a Link State Update message with an invalid IPv6 prefix length.

La implementación de OSPFv3 en ospf6d en Quagga anteriores a v0.99.19 permite a atacantes remotos causar una denegación de servicio (acceso de memoria fuera de rango y la caída del demonio) a través de un mensaje de actualización de enlace del Estado con una longitud de prefijo IPv6 inválida.

Quagga is a TCP/IP based routing software suite. The Quagga bgpd daemon implements the BGP routing protocol. The Quagga ospfd and ospf6d daemons implement the OSPF routing protocol. A heap-based buffer overflow flaw was found in the way the bgpd daemon processed malformed Extended Communities path attributes. An attacker could send a specially-crafted BGP message, causing bgpd on a target system to crash or, possibly, execute arbitrary code with the privileges of the user running bgpd. The UPDATE message would have to arrive from an explicitly configured BGP peer, but could have originated elsewhere in the BGP network.
