Descriptions

Stack-based buffer overflow in the new_msg_lsa_change_notify function in the OSPFD API (ospf_api.c) in Quagga before 0.99.22.2, when --enable-opaque-lsa and the -a command line option are used, allows remote attackers to cause a denial of service (crash) via a large LSA.

Desbordamiento de pila en la función new_msg_lsa_change_notify en OSPFD API (ospf_api.c) anterior a 0.99.222, cuando las opciones de línea de comandos --enable-opaque-lsa y -a son utilizadas, permite a atacantes rmeotos causar una denegación de servicio (crash) a través de un LSA grande.

A stack-based buffer overflow flaw was found in the way the Quagga OSPFD daemon handled LSA (link-state advertisement) packets. A remote attacker could use this flaw to crash the ospfd daemon resulting in denial of service.

Kostya Kortchinsky discovered that Quagga incorrectly handled certain route data when configured with BGP peers enabled for VPNv4. A remote attacker could use this issue to cause Quagga to crash, resulting in a denial of service, or possibly execute arbitrary code. It was discovered that Quagga incorrectly handled messages with a large LSA when used in certain configurations.
