CVE-2018-5379

The Quagga BGP daemon bgpd prior to version 1.2.3 can double-free memory when processing certain forms of UPDATE message, containing cluster-list and/or unknown attributes. A successful attack could cause a denial of service or potentially allow an attacker to execute arbitrary code...

CVE-2018-5381

The Quagga BGP daemon bgpd prior to version 1.2.3 has a bug in its parsing of "Capabilities" in BGP OPEN messages, in the bgppacket.c:bgpcapabilitymsgparse function. The parser can enter an infinite loop on invalid capabilities if a Multi-Protocol capability does not have a recognized AFI/SAFI,...
