pyasn1: pyasn1: Denial of Service due to memory exhaustion from malformed RELATIVE-OID

A flaw was found in pyasn1, a generic ASN.1 library for Python. A remote attacker could exploit this vulnerability by sending a specially crafted RELATIVE-OID with excessive continuation octets. This input validation vulnerability leads to memory exhaustion, resulting in a Denial of Service DoS f...
