Dnsmasq before 2.66test2, when used with certain libvirt configurations, replies to queries from prohibited interfaces, which allows remote attackers to cause a denial of service (traffic amplification) via spoofed TCP based DNS queries. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-3411. Dnsmasq anterior a v2.66test2, cuando se utiliza con ciertas configuraciones de libvirt, responde a consultas desde interfaces prohibidas, lo que permite a atacantes remotos provocar una denegación de servicio (amplificación de tráfico) a través de falsas consultas DNS mediante TCP. NOTA: esta vulnerabilidad se debe a un fix incompleto para CVE-2012-3411. • http://www.mandriva.com/security/advisories?name=MDVSA-2013:072 http://www.openwall.com/lists/oss-security/2013/01/18/2 http://www.openwall.com/lists/oss-security/2013/01/18/7 http://www.thekelleys.org.uk/gitweb/?p=dnsmasq.git%3Ba=commitdiff%3Bh=22ce550e5346947a12a781ed0959a7b1165d0dc6 https://bugzilla.redhat.com/show_bug.cgi?id=894486 • CWE-20: Improper Input Validation •

Dnsmasq before 2.63test1, when used with certain libvirt configurations, replies to requests from prohibited interfaces, which allows remote attackers to cause a denial of service (traffic amplification) via a spoofed DNS query. Dnsmasq anterior a v2.63test1, cuando se usa con determinadas configuraciones en libvirt, contesta a las peticiones desde interfaces prohibidas, lo que permite a atacantes remotos provocar una denegación de servicios (amplificación de tráfico) a través de una petición DNS falsificada. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=683372 http://rhn.redhat.com/errata/RHSA-2013-0276.html http://rhn.redhat.com/errata/RHSA-2013-0277.html http://rhn.redhat.com/errata/RHSA-2013-0579.html http://thekelleys.org.uk/gitweb/?p=dnsmasq.git%3Ba=commitdiff%3Bh=2f38141f434e23292f84cefc33e8de76fb856147 http://thekelleys.org.uk/gitweb/?p=dnsmasq.git%3Ba=commitdiff%3Bh=54dd393f3938fc0c19088fbd319b95e37d81a2b0 http://www.mandriva.com/security/advisories?name=MDVSA-2013:072 http://www.openwall.c • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2009-2957
Heap-based buffer overflow in the tftp_request function in tftp.c in dnsmasq before 2.50, when --enable-tftp is used, might allow remote attackers to execute arbitrary code via a long filename in a TFTP packet, as demonstrated by a read (aka RRQ) request. Desbordamiento de búfer basado en memoria dinámica en la función tftp_request en tftp.c en dnsmasq anterior v2.50, cuando --enable-tftp es usado, puede permitir a atacantes remotos ejecutar código a su elección a través de un nombre de fichero largo en un paquete TFTP, como queda demostrado en una lectura de respuesta (RRQ). • https://www.exploit-db.com/exploits/9617 http://secunia.com/advisories/36563 http://www.coresecurity.com/content/dnsmasq-vulnerabilities http://www.redhat.com/support/errata/RHSA-2009-1238.html http://www.securityfocus.com/bid/36121 http://www.thekelleys.org.uk/dnsmasq/CHANGELOG http://www.ubuntu.com/usn/USN-827-1 https://bugzilla.redhat.com/show_bug.cgi?id=519020 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A10538 https://rhn.redhat.c • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The tftp_request function in tftp.c in dnsmasq before 2.50, when --enable-tftp is used, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a TFTP read (aka RRQ) request with a malformed blksize option. La función tftp_request en tftp.c en dnsmasq en versiones anteriores a la 2.50, cuando se usa --enable-tftp, permite a atacantes remotos provocar una denegación de servicio (referencia a un puntero nulo y caída del demonio) mediante una petición de lectura TFTP (alias RRQ) con una opción blksize malformada. • https://www.exploit-db.com/exploits/9617 http://secunia.com/advisories/36563 http://www.coresecurity.com/content/dnsmasq-vulnerabilities http://www.redhat.com/support/errata/RHSA-2009-1238.html http://www.securityfocus.com/bid/36120 http://www.thekelleys.org.uk/dnsmasq/CHANGELOG http://www.ubuntu.com/usn/USN-827-1 https://bugzilla.redhat.com/show_bug.cgi?id=519020 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A9816 https://rhn.redhat.co • CWE-399: Resource Management Errors •

dnsmasq 2.43 allows remote attackers to cause a denial of service (daemon crash) by (1) sending a DHCPINFORM while lacking a DHCP lease, or (2) attempting to renew a nonexistent DHCP lease for an invalid subnet as an "unknown client," a different vulnerability than CVE-2008-3214. dnsmasq 2.43 permite a atacantes remotos provocar una denegación de servicio (caída de monio) mediante (1) el envío de un DHCPINFORM en ausencia de una asignación DHCP o (2) intentando renovar una asignación DHCP no existente para una subred inválida como "cliente desconocido".
