CVSS: 7.5EPSS: 0%CPEs: 7EXPL: 1CVE-2019-6470 – dhcpd: use-after-free error leads crash in IPv6 mode when using mismatched BIND libraries
https://notcve.org/view.php?id=CVE-2019-6470
There had existed in one of the ISC BIND libraries a bug in a function that was used by dhcpd when operating in DHCPv6 mode. 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. • https://access.redhat.com/errata/RHSA-2019:2060 https://access.redhat.com/errata/RHSA-2019:3525 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=896122 https://lists.opensuse.org/opensuse-security-announce/2019-10/msg00048.html https://lists.opensuse.org/opensuse-security-announce/2019-10/msg00049.html https://access.redhat.com/security/cve/CVE-2019-6470 https://bugzilla.redhat.com/show_bug.cgi?id=1708641 • CWE-20: Improper Input Validation •

The supersede_lease function in memory.c in ISC DHCP (dhcpd) server 2.0pl5 allows remote attackers to cause a denial of service (application crash) via a DHCPDISCOVER packet with a 32 byte client-identifier, which causes the packet to be interpreted as a corrupt uid and causes the server to exit with "corrupt lease uid." La función supersede_lease en memory.c de ISC DHCP (dhcpd) server 2.0p15 permite a atacantes remotos provocar una denegación de servicio (cierre de aplicación) mediante un paquete DHCPDISCOVER con un identificador de cliente de 32 bytes, lo que provoca que el paquete sea interpretado como un uid corrupto y provoca que el server se cierre con un mensaje "corrupt lease uid". • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=380273 http://secunia.com/advisories/21345 http://secunia.com/advisories/21363 http://secunia.com/advisories/21655 http://securitytracker.com/id?1016755 http://www.debian.org/security/2006/dsa-1143 http://www.openbsd.org/errata.html#dhcpd http://www.securityfocus.com/bid/19348 http://www.vupen.com/english/advisories/2006/3158 • CWE-399: Resource Management Errors •
