pyasn1: pyasn1 Vulnerable to Denial of Service via Unbounded Recursion

An unbounded recursion flaw has been discovered in the pypi pyasn1 library. This uncontrolled recursion occurs when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing nested SEQUENCE 0x30 or SET 0x31 tags with Indefinite Length 0x80 markers. Thi...
