Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In Legion of the Bouncy Castle BC before 1.61 and BC-FJA before 1.0.1.2, attackers can obtain sensitive
information about a private exponent because of Observable Differences in Behavior to Error Inputs. This
occurs in org.bouncycastle.crypto.encodings.OAEPEncoding. Sending invalid ciphertext that decrypts to a
short payload in the OAEP Decoder could result in the throwing of an early exception, potentially leaking
some information about the private exponent of the RSA private key performing the encryption.
(CVE-2020-26939)
