CVE-2012-0249
Buffer overflow in the ospf_ls_upd_list_lsa function in ospf_packet.c
in the OSPFv2 implementation in ospfd in Quagga before 0.99.20.1
allows remote attackers to cause a denial of service (assertion
failure and daemon exit) via a Link State Update (aka LS Update)
packet that is smaller than the length specified in its header.
CVE-2012-0250
Buffer overflow in the OSPFv2 implementation in ospfd in Quagga before
0.99.20.1 allows remote attackers to cause a denial of service (daemon
crash) via a Link State Update (aka LS Update) packet containing a
network-LSA link-state advertisement for which the data-structure
length is smaller than the value in the Length header field.
CVE-2012-0255
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).");
