https://notcve.org/view.php?id=CVE-2010-1321
The kg_accept_krb5 function in krb5/accept_sec_context.c in the GSS-API library in MIT Kerberos 5 (aka krb5) through 1.7.1 and 1.8 before 1.8.2, as used in kadmind and other applications, does not properly check for invalid GSS-API tokens, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an AP-REQ message in which the authenticator's checksum field is missing. Vulnerabilidad en la función "kg_accept_krb5" en "krb5/accept_sec_context.c" de la librería GSS-API en MIT Kerberos v5 (también conocido como krb5) a través de v1.7.1 y v1.8 anterior a v1.8.2, como los usados en "kadmind" y otras aplicaciones, no comprueban adecuadamente vales (tokens) GSS-API inválidos, que permiten a usuarios autenticados remotamente causar una denegación de servicio (referencia a puntero nulo y caída del demonio) a través de un mensaje AP-REQ en el cual se pierde el campo "checksum" del usuario autenticado. • http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c02257427 http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041615.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041645.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041654.html http://lists.opensuse.org/opensuse-security-announce/2010-06/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2010-08/msg00001.html http://lists.opensuse.org/opensuse-security-announce • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2009-0846
The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.c in the ASN.1 GeneralizedTime decoder in MIT Kerberos 5 (aka krb5) before 1.6.4 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via vectors involving an invalid DER encoding that triggers a free of an uninitialized pointer. La función asn1_decode_generaltime en lib/krb5/asn.1/asn1_decode.c en el decodificador ASN.1 GeneralizedTime en MIT Kerberos 5 (también conocido como Krb5) anteriores a v1.6.4, permite a atacantes remotos provocar una denegación de servicio (caída del demonio) o posiblemente ejecución de código de su elección a través de vectores que implican una codificación DER inválida, que provocará una liberación del puntero no inicializado. • http://lists.apple.com/archives/security-announce/2009/May/msg00002.html http://lists.vmware.com/pipermail/security-announce/2009/000059.html http://marc.info/?l=bugtraq&m=124896429301168&w=2 http://marc.info/?l=bugtraq&m=130497213107107&w=2 http://rhn.redhat.com/errata/RHSA-2009-0409.html http://rhn.redhat.com/errata/RHSA-2009-0410.html http://secunia.com/advisories/34594 http://secunia.com/advisories/34598 http://secunia.com/advisories/34617 http://secunia.com/adv • CWE-416: Use After Free CWE-824: Access of Uninitialized Pointer •

KDC in MIT Kerberos 5 (krb5kdc) does not set a global variable for some krb4 message types, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted messages that trigger a NULL pointer dereference or double-free. KDC en MIT Kerberos 5 (krb5kdc) no fija variable global alguna para determinados tipos de mensaje krb4, la cual permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente ejecución de código de su elección mediante mensajes manipulados que disparan una referencia a un puntero nulo o doble liberación de memoria (double-free). • http://docs.info.apple.com/article.html?artnum=307562 http://lists.apple.com/archives/security-announce/2008/Mar/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2008-03/msg00006.html http://marc.info/?l=bugtraq&m=130497213107107&w=2 http://secunia.com/advisories/29420 http://secunia.com/advisories/29423 http://secunia.com/advisories/29424 http://secunia.com/advisories/29428 http://secunia.com/advisories/29435 http://secunia.com/advisories/29438 http://secun • CWE-665: Improper Initialization •
