1 CVE-2021-43398 203 +Info 2021-11-04 2021-12-17
5.0
None Remote Low Not required Partial None None
** DISPUTED ** Crypto++ (aka Cryptopp) 8.6.0 and earlier contains a timing leakage in MakePublicKey(). There is a clear correlation between execution time and private key length, which may cause disclosure of the length information of the private key. This might allow attackers to conduct timing attacks. NOTE: this report is disputed by the vendor and multiple third parties. The execution-time differences are intentional. A user may make a choice of a longer key as a tradeoff between strength and performance. In making this choice, the amount of information leaked to an adversary is of infinitesimal value.
2 CVE-2021-40530 327 2021-09-06 2021-10-18
2.6
None Remote High Not required Partial None None
The ElGamal implementation in Crypto++ through 8.5 allows plaintext recovery because, during interaction between two cryptographic libraries, a certain dangerous combination of the prime defined by the receiver's public key, the generator defined by the receiver's public key, and the sender's ephemeral exponents can lead to a cross-configuration attack against OpenPGP.
3 CVE-2019-14318 417 +Info 2019-07-30 2019-08-20
4.3
None Remote Medium Not required Partial None None
Crypto++ 8.3.0 and earlier contains a timing side channel in ECDSA signature generation. This allows a local or remote attacker, able to measure the duration of hundreds to thousands of signing operations, to compute the private key used. The issue occurs because scalar multiplication in ecp.cpp (prime field curves, small leakage) and algebra.cpp (binary field curves, large leakage) is not constant time and leaks the bit length of the scalar among other information.
4 CVE-2017-9434 125 2017-06-05 2019-06-01
5.0
None Remote Low Not required Partial None None
Crypto++ (aka cryptopp) through 5.6.5 contains an out-of-bounds read vulnerability in zinflate.cpp in the Inflator filter.
5 CVE-2016-7420 200 +Info 2016-09-16 2016-11-28
4.3
None Remote Medium Not required Partial None None
Crypto++ (aka cryptopp) through 5.6.4 does not document the requirement for a compile-time NDEBUG definition disabling the many assert calls that are unintended in production use, which might allow context-dependent attackers to obtain sensitive information by leveraging access to process memory after an assertion failure, as demonstrated by reading a core dump.
6 CVE-2016-3995 200 +Info 2017-02-13 2017-03-03
5.0
None Remote Low Not required Partial None None
The timing attack protection in Rijndael::Enc::ProcessAndXorBlock and Rijndael::Dec::ProcessAndXorBlock in Crypto++ (aka cryptopp) before 5.6.4 may be optimized out by the compiler, which allows attackers to conduct timing attacks.
