Multiple memory leaks in ISC DHCP 4.1.x and 4.2.x before 4.2.4-P1 and 4.1-ESV before 4.1-ESV-R6 allow remote attackers to cause a denial of service (memory consumption) by sending many requests. Múltiples fugas de memoria en ISC DHCP 4.1.x y 4.2.x anterior a 4.2.4-P1 y 4.1-ESV anterior a 4.1-ESV-R6, permite a atacantes remotos provocar una denegación de servicio (consumo de memoria) mediante el envío de multitud de peticiones. • http://lists.opensuse.org/opensuse-updates/2012-08/msg00030.html http://rhn.redhat.com/errata/RHSA-2012-1141.html http://security.gentoo.org/glsa/glsa-201301-06.xml http://www.debian.org/security/2012/dsa-2516 http://www.debian.org/security/2012/dsa-2519 http://www.mandriva.com/security/advisories?name=MDVSA-2012:115 http://www.mandriva.com/security/advisories?name=MDVSA-2012:116 http://www.securityfocus.com/bid/54665 http://www.securitytracker.com/id?1027300 http://w • CWE-399: Resource Management Errors CWE-401: Missing Release of Memory after Effective Lifetime •

The logging functionality in dhcpd in ISC DHCP before 4.2.3-P2, when using Dynamic DNS (DDNS) and issuing IPv6 addresses, does not properly handle the DHCPv6 lease structure, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via crafted packets related to a lease-status update. La funcionalidad de registro en el dhcpd de ISC DHCP anterior a v4.2.3-P2, cuando se utiliza DNS dinámico (DDNS) y direcciones IPv6, no maneja correctamente la estructura de arrendamiento (lease structure) DHCPv6, permitiendo a atacantes remotos provocar una denegación de servicio (puntero a NULL y el caída del servicio) mediante paquetes especialmente elaborados en relación con una actualización lease-status. • http://security.gentoo.org/glsa/glsa-201301-06.xml https://deepthought.isc.org/article/AA-00595 https://kb.isc.org/article/AA-00705 https://www.isc.org/software/dhcp/advisories/cve-2011-4868 • CWE-399: Resource Management Errors •
