GHSA-M4P7-R5RC-7G4J pyasn1 BER/CER/DER decoder denial of service via unbounded long-form tag IDs

Impact The BER decoder shared by the CER and DER codecs parses long-form tags by accumulating continuation octets in a loop with no upper bound on the size of the tag ID. A crafted input can force the decoder to build an arbitrarily large integer, with CPU cost growing quadratically in input size...
