CVE-2012-1033 – bind: deleted domain name resolving flaw
https://notcve.org/view.php?id=CVE-2012-1033
The resolver in ISC BIND 9 through 9.8.1-P1 overwrites cached server names and TTL values in NS records during the processing of a response to an A record query, which allows remote attackers to trigger continued resolvability of revoked domain names via a "ghost domain names" attack. La resolución en ISC BIND v9 a v9.8.1-P1 no implementa una política de actualización de caché, que permite a atacantes remotos provocar resolubilidad continuada de nombres de dominio que ya no están registrados a través de un "Ghost Names exploit" • http://marc.info/?l=bugtraq&m=135638082529878&w=2 http://osvdb.org/78916 http://rhn.redhat.com/errata/RHSA-2012-0717.html http://secunia.com/advisories/47884 http://www.kb.cert.org/vuls/id/542123 http://www.securityfocus.com/bid/51898 http://www.securitytracker.com/id?1026647 https://exchange.xforce.ibmcloud.com/vulnerabilities/73053 https://hermes.opensuse.org/messages/15136456 https://hermes.opensuse.org/messages/15136477 https://www.isc.org/software/bind/advisories/ •
CVE-2011-4868
https://notcve.org/view.php?id=CVE-2011-4868
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 •
CVE-2011-4539 – dhcp: DoS due to processing certain regular expressions
https://notcve.org/view.php?id=CVE-2011-4539
dhcpd in ISC DHCP 4.x before 4.2.3-P1 and 4.1-ESV before 4.1-ESV-R4 does not properly handle regular expressions in dhcpd.conf, which allows remote attackers to cause a denial of service (daemon crash) via a crafted request packet. dhcpd en ISC DHCP v4.x antes de v4.2.3-P1 y v4.1-ESV antes de v4.1-ESV-R4 no manipula correctamente expresiones regulares en dhcpd.conf, lo que permite a atacantes remotos provocar una denegación de servicio (caída del deminio) a través de un paquete de petición modificado. • http://lists.fedoraproject.org/pipermail/package-announce/2011-December/070980.html http://lists.fedoraproject.org/pipermail/package-announce/2012-January/071549.html http://lists.opensuse.org/opensuse-updates/2011-12/msg00006.html http://secunia.com/advisories/47153 http://secunia.com/advisories/47178 http://security.gentoo.org/glsa/glsa-201301-06.xml http://www.debian.org/security/2012/dsa-2519 http://www.mandriva.com/security/advisories?name=MDVSA-2011:182 http://www.securityfocus.com/bi • CWE-20: Improper Input Validation •
CVE-2011-4313 – bind: Remote denial of service against recursive servers via logging negative cache entry
