Unsafe Decoding

pyasn1 performs unsafe canonical decoding. The libraries canonical decoders incorrectly decodes non-canonical variations and produces more than one valid substrate. This could potentially lead to a bypass in protection if left unchecked...

Denial Of Service (DoS)

pyasn1 is vulnerable to denial of service DoS attacks. These attacks are possible because the libraries finite length decoders could process indefinite length input for serialization. This is due to it not checking that the input is less than the maxChunkSize...
