CVE-2011-1530 – (krb5kdc): NULL pointer dereference in the TGS handling (MITKRB5-SA-2011-007)

https://notcve.org/view.php?id=CVE-2011-1530

The process_tgs_req function in do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.9 through 1.9.2 allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted TGS request that triggers an error other than the KRB5_KDB_NOENTRY error. La función process_tgs_req en do_tgs_req.c en Key Distribution Center (KDC) en MIT Kerberos 5 (también conocido como krb5) v1.9 hasta v1.9.2 permite a usuarios autenticados remotamente provocar una denegación de servicio (desreferencia a puntero nulo y caída del demonio) a través de una petición TGS modificada que provoca un error diferente del error KRB5_KDB_NOENTRY. • http://secunia.com/advisories/47124 http://securitytracker.com/id?1026374 http://web.mit.edu/kerberos/advisories/MITKRB5-SA-2011-007.txt http://www.mandriva.com/security/advisories?name=MDVSA-2011:184 http://www.redhat.com/support/errata/RHSA-2011-1790.html http://www.securityfocus.com/archive/1/520756/100/0/threaded http://www.securityfocus.com/bid/50929 https://exchange.xforce.ibmcloud.com/vulnerabilities/71655 https://access.redhat.com/security/cve/CVE-2011-1530 https://bu • CWE-399: Resource Management Errors CWE-476: NULL Pointer Dereference •
