Descriptions

Off-by-one error in the krb5_encode_krbsecretkey function in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the LDAP KDB module in kadmind in MIT Kerberos 5 (aka krb5) 1.6.x through 1.11.x before 1.11.6 and 1.12.x before 1.12.2 allows remote authenticated users to cause a denial of service (buffer overflow) or possibly execute arbitrary code via a series of "cpw -keepold" commands.

Error de superación de límite (off-by-one) en la función krb5_encode_krbsecretkey en plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c en el módulo LDAP KDB en kadmind en MIT Kerberos 5 (también conocido como krb5) 1.6.x hasta 1.11.x anterior a 1.11.6 y 1.12.x anterior a 1.12.2 permite a usuarios remotos autenticados causar una denegación de servicio (desbordamiento de buffer) o posiblemente ejecutar código arbitrario a través de una serie de comandos 'cpw -keepold'.

A buffer overflow was found in the KADM5 administration server (kadmind) when it was used with an LDAP back end for the KDC database. A remote, authenticated attacker could potentially use this flaw to execute arbitrary code on the system running kadmind.
