CVSS: 10.0EPSS: 62%CPEs: 18EXPL: 0CVE-2009-0846 – krb5: ASN.1 decoder can free uninitialized pointer when decoding an invalid encoding (MITKRB5-SA-2009-002)
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 •

The Kerberos 4 support in KDC in MIT Kerberos 5 (krb5kdc) does not properly clear the unused portion of a buffer when generating an error message, which might allow remote attackers to obtain sensitive information, aka "Uninitialized stack values."
