| CVE-2016-1000342 | 2 Bouncycastle, Debian | 2 Legion-of-the-bouncy-castle-java-crytography-api, Debian Linux | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2016-1000341 | 2 Bouncycastle, Debian | 2 Legion-of-the-bouncy-castle-java-crytography-api, Debian Linux | 2024-11-21 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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. | |||||
| CVE-2016-1000340 | 1 Bouncycastle | 1 Legion-of-the-bouncy-castle-java-crytography-api | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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 (org.bouncycastle.math.ec.custom.**), so there was the possibility of rare (in general usage) spurious calculations for elliptic curve scalar multiplications. Such errors would have been detected with high probability by the output validation for our scalar multipliers. | |||||
| CVE-2016-1000339 | 2 Bouncycastle, Debian | 2 Legion-of-the-bouncy-castle-java-crytography-api, Debian Linux | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| 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 the primary AES class for the BC JCE provider from 1.56. Use of AESFastEngine is now only recommended where otherwise deemed appropriate. | |||||
