CVE-2016-1000340

In the Bouncy Castle JCE Provider versions 1.51 to 1.55, a carry propagation bug was introduced in the implementation of squaring for several raw math classes have been fixed org.bouncycastle.math.raw.Nat???. These classes are used by our custom elliptic curve implementations...

CVE-2016-1000341

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

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-2016-1000339

CVE-2016-1000339 describes a cryptographic leakage in Bouncy Castle JCE Provider v1.55 and earlier, where the primary AES engine class was AESFastEngine. Because of the table-driven lookup, data channel timing could leak information about the AES key via table accesses; AESEngine also had leaks b...

CVE-2016-1000340

The CVE-2016-1000340 issue describes a carry propagation bug in the Bouncy Castle JCE Provider (versions 1.51–1.55) affecting the squaring path of several Nat-based raw math classes used by custom EC implementations. This could cause rare, spurious calculations during elliptic-curve scalar multip...

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-2016-1000343

CVE-2016-1000343 affects the Bouncy Castle JCE Provider (1.55 and earlier). When the JCA key pair generator is not explicitly initialised with DSA parameters, it may generate a weak private key by assuming a 1024-bit key size. Publicly available documents confirm this issue and recommend either e...

CVE-2016-1000343

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...

CVE-2016-1000339

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...

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 ...
