{"id":"CVE-2016-10396","details":"The racoon daemon in IPsec-Tools 0.8.2 contains a remotely exploitable computational-complexity attack when parsing and storing ISAKMP fragments. The implementation permits a remote attacker to exhaust computational resources on the remote endpoint by repeatedly sending ISAKMP fragment packets in a particular order such that the worst-case computational complexity is realized in the algorithm utilized to determine if reassembly of the fragments can take place.","modified":"2026-03-15T22:04:35.690731Z","published":"2017-07-06T01:29:00.177Z","related":["SUSE-SU-2018:0423-1","SUSE-SU-2018:0424-1"],"references":[{"type":"ADVISORY","url":"http://cvsweb.netbsd.org/bsdweb.cgi/src/crypto/dist/ipsec-tools/src/racoon/isakmp_frag.c.diff?r1=1.5&r2=1.5.36.1"},{"type":"ADVISORY","url":"http://cvsweb.netbsd.org/bsdweb.cgi/src/crypto/dist/ipsec-tools/src/racoon/isakmp_frag.c?only_with_tag=MAIN"},{"type":"ADVISORY","url":"https://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=51682"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"0.8.2"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2016-10396.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
