Descriptions

The gssrpc__svcauth_gssapi function in the RPC library in MIT Kerberos 5 (krb5) 1.6.1 and earlier might allow remote attackers to execute arbitrary code via a zero-length RPC credential, which causes kadmind to free an uninitialized pointer during cleanup.

La función gssrpc__svcauth_gssapi en la librería RPC de MIT Kerberos 5 (krb5) 1.6.1 y anteriores podría permitir a atacantes remotos ejecutar código de su elección mediante credenciales RPC de longitud cero, lo cual provoca que kadmind libere un puntero no inicializado durante la limpieza.
