CVE-2016-1000341

CVE-2016-1000341 : The Bouncy Castle JCE Provider (BC-JCE) up to version 1.55 and earlier suffers a timing-side-channel in DSA signature generation. The lack of blinding can allow an observer to deduce the signature’s k value, potentially leaking the private key. The vulnerability is tied to the ...

CVE-2016-1000342

CVE-2016-1000342 is associated with Bouncy Castle JCE Provider up to version 1.55 and earlier, where ECDSA does not fully validate ASN.1 encoding of signatures during verification. This can allow injection of extra elements in the signature sequence and may permit the introduction of “invisible” ...

CVE-2016-1000341: Undefined Security Weakness

In the Bouncy Castle JCE Provider version 1.55 and earlier DSA signature generation is vulnerable to timing attack. Where timings can be closely observed for the generation of signatures, the lack of blinding in 1.55, or earlier, may allow an attacker to gain information about the signature's k...

CVE-2016-1000342: Improper Verification of Cryptographic Signature

In the Bouncy Castle JCE Provider version 1.55 and earlier ECDSA does not fully validate ASN.1 encoding of signature on verification. It is possible to inject extra elements in the sequence making up the signature and still have it validate, which in some cases may allow the introduction of...

CVE-2016-1000344: Undefined Security Weakness

In the Bouncy Castle JCE Provider version 1.55 and earlier the DHIES implementation allowed the use of ECB mode. This mode is regarded as unsafe and support for it has been removed from the provider...

CVE-2016-1000352: Undefined Security Weakness

CVE-2016-1000345: Undefined Security Weakness

In the Bouncy Castle JCE Provider version 1.55 and earlier the DHIES/ECIES CBC mode vulnerable to padding oracle attack. For BC 1.55 and older, in an environment where timings can be easily observed, it is possible with enough observations to identify when the decryption is failing due to padding...

PT-2018-4639

Name of the Vulnerable Software and Affected Versions Bouncy Castle JCE Provider versions 1.55 and earlier Description The issue concerns a padding oracle attack in the DHIES/ECIES CBC mode.

PT-2018-4641

Name of the Vulnerable Software and Affected Versions Bouncy Castle JCE Provider versions 1.55 and earlier Description The issue concerns the use of ECB mode in the ECIES implementation, which is considered unsafe. Support for this mode has been removed due to its unsafe nature. Recommendations F...

CVE-2016-1000346

In the Bouncy Castle JCE Provider version 1.55 and earlier the other party DH public key is not fully validated. This can cause issues as invalid keys can be used to reveal details about the other party's private key where static Diffie-Hellman is in use. As of release 1.56 the key parameters are...

CVE-2016-1000339: Undefined Security Weakness

In the Bouncy Castle JCE Provider version 1.55 and earlier the primary engine class used for AES was AESFastEngine. Due to the highly table driven approach used in the algorithm it turns out that if the data channel on the CPU can be monitored the lookup table accesses are sufficient to leak...
