Crypto++ through 8.4 contains a timing side channel in ECDSA signature generation. Function FixedSizeAllocatorWithCleanup could write to memory outside of the allocation if the allocated memory was not 16-byte aligned. NOTE: this issue exists because the CVE-2019-14318 fix was intentionally removed for functionality reasons. Scope: local bookworm: open bullsey

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-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

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

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.

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.

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. Scope: local bookworm: resolved bullseye: resolved forky: resolved sid: resolved trixie: resolved
