Descriptions

The BGP implementation in bgpd in Quagga before 0.99.20.1 does not properly use message buffers for OPEN messages, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a message associated with a malformed Four-octet AS Number Capability (aka AS4 capability).

La implementación de BGP en bgpd en Quagga antes v0.99.20.1 no utiliza adecuadamente los búferes de mensajes para los mensajes marcados como OPEN, lo que permite a atacantes remotos provocar una denegación de servicio (error de aserción y salida del demonio) a través de un mensaje asociado con un ASN de cuatro octetos mal formado(también conocido como funcionalidad AS4).

Multiple vulnerabilities have been found in Quagga, the worst of which could lead to arbitrary code execution. Versions less than 0.99.22.4 are affected.
