04 Jun 2018 — 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 value and ultimately the private value as well.

04 Jun 2018 — 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 'invisible' data into a signed structure.

https://notcve.org/view.php?id=CVE-2016-1000339
04 Jun 2018 — 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 information on the AES key being used. There was also a leak in AESEngine although it was substantially less. AESEngine has been modified to remove any signs of leakage (testing carried out on Intel X86-64) and is now t... • https://access.redhat.com/errata/RHSA-2018:2669 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-310: Cryptographic Issues •

04 Jun 2018 — In the Bouncy Castle JCE Provider version 1.55 and earlier the DSA key pair generator generates a weak private key if used with default values. If the JCA key pair generator is not explicitly initialised with DSA parameters, 1.55 and earlier generates a private value assuming a 1024 bit key size. In earlier releases this can be dealt with by explicitly passing parameters to the key pair generator.

CVSS: 5.1EPSS: 0%CPEs: 3EXPL: 0CVE-2018-5382 – Bouncy Castle BKS-V1 keystore files vulnerable to trivial hash collisions
https://notcve.org/view.php?id=CVE-2018-5382
16 Apr 2018 — The default BKS keystore use an HMAC that is only 16 bits long, which can allow an attacker to compromise the integrity of a BKS keystore. Bouncy Castle release 1.47 changes the BKS format to a format which uses a 160 bit HMAC instead. This applies to any BKS keystore generated prior to BC 1.47. For situations where people need to create the files for legacy reasons a specific keystore type "BKS-V1" was introduced in 1.49. It should be noted that the use of "BKS-V1" is discouraged by the library authors and... • http://www.securityfocus.com/bid/103453 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-354: Improper Validation of Integrity Check Value •
