| CVE-2021-43398 | 1 Cryptopp | 1 Crypto\+\+ | 2022-04-18 | 5.0 MEDIUM | 5.3 MEDIUM |
| ** 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. | |||||
| CVE-2021-40530 | 2 Cryptopp, Fedoraproject | 2 Crypto\+\+, Fedora | 2021-10-18 | 2.6 LOW | 5.9 MEDIUM |
| 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. | |||||
| CVE-2019-14318 | 1 Cryptopp | 1 Crypto\+\+ | 2019-08-20 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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. | |||||
| CVE-2016-9939 | 2 Cryptopp, Debian | 2 Crypto\+\+, Debian Linux | 2019-05-31 | 5.0 MEDIUM | 7.5 HIGH |
| Crypto++ (aka cryptopp and libcrypto++) 5.6.4 contained a bug in its ASN.1 BER decoding routine. The library will allocate a memory block based on the length field of the ASN.1 object. If there is not enough content octets in the ASN.1 object, then the function will fail and the memory block will be zeroed even if its unused. There is a noticeable delay during the wipe for a large allocation. | |||||
| CVE-2017-9434 | 1 Cryptopp | 1 Crypto\+\+ | 2019-05-31 | 5.0 MEDIUM | 5.3 MEDIUM |
| Crypto++ (aka cryptopp) through 5.6.5 contains an out-of-bounds read vulnerability in zinflate.cpp in the Inflator filter. | |||||
| CVE-2015-2141 | 2 Cryptopp, Opensuse | 2 Crypto\+\+ Library, Opensuse | 2018-10-30 | 5.0 MEDIUM | N/A |
| The InvertibleRWFunction::CalculateInverse function in rw.cpp in libcrypt++ 5.6.2 does not properly blind private key operations for the Rabin-Williams digital signature algorithm, which allows remote attackers to obtain private keys via a timing attack. | |||||
| CVE-2016-3995 | 1 Cryptopp | 1 Crypto\+\+ | 2017-03-03 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2016-7544 | 2 Cryptopp, Microsoft | 2 Crypto\+\+, Windows | 2017-02-07 | 5.0 MEDIUM | 7.5 HIGH |
| Crypto++ 5.6.4 incorrectly uses Microsoft's stack-based _malloca and _freea functions. The library will request a block of memory to align a table in memory. If the table is later reallocated, then the wrong pointer could be freed. | |||||
| CVE-2016-7420 | 1 Cryptopp | 1 Crypto\+\+ | 2016-11-28 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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. | |||||
