  • GHSA-6jmw-6mxw-w4jcBER/CER/DER decoder panics on invalid input2023-09-13ghsa · osvUS

    NLnet Labs’ bcder library up to and including version 0.7.2 panics while decoding certain invalid input data rather than rejecting the data with an error. This can affect both the actual decoding stage as well as accessing content of types that utilized delayed decoding.

  • RUSTSEC-2023-0062BER/CER/DER decoder panics on invalid input2023-09-13vendor · osvUS

    Due to insufficient checking of input data, decoding certain data sequences can lead to _bcder_ panicking rather than returning an error. This can affect both the actual decoding stage as well as accessing content of types that utilized delayed decoding. bcder 0.7.3 fixes these issues by more thoroughly checking inputs and returning errors as expected.
