QID 982394

QID 982394: Java (maven) Security Update for org.bouncycastle:bc-fips (GHSA-72m5-fvvv-55m6)

In Legion of the Bouncy Castle BC before 1.55 and BC-FJA before 1.0.2, 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.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.

  • CVSS V3 rated as Medium - 5.3 severity.
