Cryptographic Issues

org.bouncycastle:bcprov-ext-jdk15on is a Java implementation of cryptographic algorithms.

Affected versions of this package are vulnerable to Cryptographic Issues via weak key-hash message authentication code (HMAC) that is only 16 bits long which can result in hash collisions, as a result of an error within the BKS version 1 keystore (BKS-V1) files and could lead to an attacker being able to affect the integrity of these files. This vulnerability was introduced following an incomplete fix for CVE-2018-5382.

How to fix Cryptographic Issues?

Upgrade org.bouncycastle:bcprov-ext-jdk15on to version 1.69 or higher.

[1.49,1.69)
  • M
Timing Attack

org.bouncycastle:bcprov-ext-jdk15on is a Java implementation of cryptographic algorithms.

Affected versions of this package are vulnerable to Timing Attack. A timing issue within the EC math library can expose information about the private key when an attacker is able to observe timing information for the generation of multiple deterministic ECDSA signatures.

How to fix Timing Attack?

Upgrade org.bouncycastle:bcprov-ext-jdk15on to version 1.66 or higher.

Information Exposure

org.bouncycastle:bcprov-ext-jdk15on is a Java implementation of cryptographic algorithms.

Affected versions of this package are vulnerable to Information Exposure. 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.

How to fix Information Exposure?

Upgrade org.bouncycastle:bcprov-ext-jdk15on to version 1.61 or higher.

Deserialization of Untrusted Data

org.bouncycastle:bcprov-ext-jdk15on is a Java implementation of cryptographic algorithms.

Affected versions of this package are vulnerable to Deserialization of Untrusted Data via the XMSS/XMSS^MT private key deserialization. A handcrafted private key could include references to unexpected classes which would be picked up from the class path for the executing application.

How to fix Deserialization of Untrusted Data?

Upgrade org.bouncycastle:bcprov-ext-jdk15on to version 1.60 or higher.
