There was also a bug in dhcpd relating to the use of this function per its documentation, but the bug in the library function prevented this from causing any harm. All releases of dhcpd from ISC contain copies of this, and other, BIND libraries in combinations that have been tested prior to release and are known to not present issues like this. Some third-party packagers of ISC software have modified the dhcpd source, BIND source, or version matchup in ways that create the crash potential. Based on reports available to ISC, the crash probability is large and no analysis has been done on how, or even if, the probability can be manipulated by an attacker. Affects: Builds of dhcpd versions prior to version 4.4.1 when using BIND versions 9.11.2 or later, or BIND versions with specific bug fixes backported to them. ISC does not have access to comprehensive version lists for all repackagings of dhcpd that are vulnerable. In particular, builds from other vendors may also be affected. Operators are advised to consult their vendor documentation.","severity":{"version":"3.1","score":6.5,"vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-08","score":0.08813,"percentile":0.95218,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"published":"2019-05-03T00:00:00Z","modified":"2026-09-21T07:02:38Z","fixes":[{"ecosystem":"Alpine:v3.11","package":"dhcp","fixed_in":["4.4.1-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.12","package":"dhcp","fixed_in":["4.4.1-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.13","package":"dhcp","fixed_in":["4.4.1-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.14","package":"dhcp","fixed_in":["4.4.1-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.15","package":"dhcp","fixed_in":["4.4.1-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.16","package":"dhcp","fixed_in":["4.4.1-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.17","package":"dhcp","fixed_in":["4.4.1-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.18","package":"dhcp","fixed_in":["4.4.1-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.19","package":"dhcp","fixed_in":["4.4.1-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.20","package":"dhcp","fixed_in":["4.4.1-r0"],"sources":["osv"]},{"ecosystem":"Azure

Affects: Builds of dhcpd versions prior to version 4.4.1 when using BIND versions 9.11.2 or later, or BIND versions with specific bug fixes backported to them. ISC does not have access to comprehensive version lists for all repackagings of dhcpd that are vulnerable. In particular, builds from other vendors may also be affected. Operators are advised to consult their vendor documentation.","status":"published","published":"2019-05-03T00:00:00Z","modified":"2026-04-22T12:21:18.171293Z","cvss":[{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high"},{"version":"3.1","score":6.5,"vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"medium"}],"updated_at":"2026-11-02T15:54:21.741399Z"},{"id":"openSUSE-SU-2019:2340-1","title":"Security update for dhcp","description":"This update for dhcp fixes the following issues:\n\nSecuirty issue fixed:\n\n- CVE-2019-6470: Fixed DHCPv6 server crashes (bsc#1134078).\n\nBug fixes:\n\n- Add compile option --enable-secs-byteorder to avoid duplicate lease warnings (bsc#1089524).\n- Use IPv6 when called as dhclient6, dhcpd6, and dhcrelay6 (bsc#1136572).\n\nThis update was imported from the SUSE:SLE-15:Update update project.","status":"published","published":"2019-10-19T22:19:08Z","modified":"2026-02-04T02:55:23.163432Z","updated_at":"2026-11-02T16:58:30.784344Z"},{"id":"openSUSE-SU-2019:2341-1","title":"Security update for dhcp","description":"This update for dhcp fixes the following issues:\n\nSecuirty issue fixed:\n\n- CVE-2019-6470: Fixed DHCPv6 server crashes (bsc#1134078).\n\nBug fixes:\n\n- Add compile option --enable-secs-byteorder to avoid duplicate lease warnings (bsc#1089524).\n- Use IPv6 when called as dhclient6, dhcpd6, and dhcrelay6 (bsc#1136572).\n\nThis update was imported from the SUSE:SLE-15:Update update project.","status":"published","published":"2019-10-19T22:19:29Z","modified":"2026-02-04T02:45:55.154409Z","updated_at":"2026-11-02T16:58:30.784344Z"},{"id":"openSUSE-SU-2024:10715-1","title":"dhcp-4.4.2.P1-2.4 on GA media","description":"These are all security issues fixed in the dhcp-4.4.2.P1-2.4 package on the GA media of openSUSE Tumbleweed.","status":"published","published":"2024-06-15T00:00:00Z","modified":"2026-02-04T04:03:03.793159Z","updated_at":"2026-11-02T16:58:34.487567Z"},{"id":"SUSE-SU-2019:2657-1","title":"Security update for dhcp","description":"This update for dhcp fixes the following issues:\n\nSecuirty issue fixed:\n\n- CVE-2019-6470: Fixed DHCPv6 server crashes (bsc#1134078).\n\nBug fixes:\n\n- Add compile option --enable-secs-byteorder to avoid duplicate lease warnings (bsc#1089524).\n- Use IPv6 when called as dhclient6, dhcpd6, and dhcrelay6 (bsc#1136572).\n","status":"published","published":"2019-10-14T15:04:21Z","modified":"2026-02-04T03:17:29.698262Z","updated_at":"2026-11-02T15:53:47.06185Z"},{"id":"SUSE-SU-2019:2727-1","title":"Security update for dhcp","description":"This update for dhcp fixes the following issues:\n\nSecuirty issue fixed:\n\n- CVE-2019-6470: Fixed DHCPv6 server crashes (bsc#1134078).\n\nBug fixes:\n\n- Add compile option --enable-secs-byteorder to avoid duplicate lease warnings (bsc#1089524).\n- Use IPv6 when called as dhclient6, dhcpd6, and dhcrelay6 (bsc#1136572).\n","status":"published","published":"2019-10-21T12:43:49Z","modified":"2026-02-04T02:14:46.01651Z","updated_at":"2026-11-02T15:53:47.06185Z"},{"id":"SUSE-SU-2019:2727-2","title":"Security update for dhcp","description":"This update for dhcp fixes the following issues:\n\nSecuirty issue fixed:\n\n- CVE-2019-6470: Fixed DHCPv6 server crashes (bsc#1134078).\n\nBug fixes:\n\n- Add compile option --enable-secs-byteorder to avoid duplicate lease warnings (bsc#1089524).\n- Use IPv6 when called as dhclient6, dhcpd6, and dhcrelay6 (bsc#1136572).\n","status":"published","published":"2019-11-12T21:32:49Z","modified":"2026-02-04T04:19:09.031894Z","updated_at":"2026-11-02T15:53:47.06185Z"},{"id":"USN-3973-1","title":"isc-dhcp vulnerability","description":"It was discovered that DHCP, when built with a mismatched external BIND\nlibrary, incorrectly handled certain memory operations.
