CVE-2010-2949
bgpd in Quagga before 0.99.17 does not properly parse AS paths, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an unknown AS type in an AS path attribute in a BGP UPDATE message.
Does this matter?
Lower severity and a low EPSS score (3.38%). Track it; it rarely justifies an emergency change on its own.
