Attackers can create long chains of CAs that would lead to OctoRPKI
exceeding its max iterations parameter. In consequence it would cause the
program to crash, preventing it from finishing the validation and leading
to a denial of service. Credits to Donika Mirdita and Haya Shulman -
Fraunhofer SIT, ATHENE, who discovered and reported this vulnerability.
