CVE-2011-3323
The OSPFv3 implementation in ospf6d in Quagga before 0.99.19 allows

invalid IPv6 prefix length.
CVE-2011-3324
The ospf6_lsa_is_changed function in ospf6_lsa.c in the OSPFv3
implementation in ospf6d in Quagga before 0.99.19 allows remote
attackers to cause a denial of service (assertion failure and daemon
exit) via trailing zero values in the Link State Advertisement (LSA)
header list of an IPv6 Database Description message.
CVE-2011-3325
ospf_packet.c in ospfd in Quagga before 0.99.19 allows remote
attackers to cause a denial of service (daemon crash) via (1) a 0x0a

packet.
CVE-2011-3326
The ospf_flood function in ospf_flood.c in ospfd in Quagga before
0.99.19 allows remote attackers to cause a denial of service (daemon

IPv4.");
