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

CVE-2016-3995 [HIGH] CVE-2016-3995: libcrypto++ - The timing attack protection in Rijndael::Enc::ProcessAndXorBlock and Rijndael::... 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-2019-14318 [MEDIUM] CVE-2019-14318: libcrypto++ - Crypto++ 8.3.0 and earlier contains a timing side channel in ECDSA signature gen... 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

CVE-2021-40530 [MEDIUM] CVE-2021-40530: libcrypto++ - The ElGamal implementation in Crypto++ through 8.5 allows plaintext recovery bec... 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

CVE-2015-2141 [MEDIUM] CVE-2015-2141: libcrypto++ - The InvertibleRWFunction::CalculateInverse function in rw.cpp in libcrypt++ 5.6.... 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.

Crypto++ (aka cryptopp) through 5.6.5 contains an out-of-bounds read vulnerability in zinflate.cpp in the Inflator filter.
