Quagga BGP attributes denial of service
| quagga-bgpattributes-dos (33547) |  Medium Risk |
Description:
Quagga is vulnerable to a denial of service, caused by improper bounds checking of the BGP attributes by the bgpd daemon. By sending a specially-crafted UPDATE message, a remote attacker could exploit this vulnerability to cause an assertion error, resulting in a denial of service.
