CVE-2023-50981

CVE-2023-50981 affects Crypto++ (cryptopp) up to version 8.9.0. The issue, described as ModularSquareRoot, allows an attacker to cause a denial of service (infinite loop) via crafted DER public-key data linked to squared odd numbers (e.g., the square of 268995137513890432434389773128616504853). P...

CVE-2023-50980

CVE-2023-50980 affects Crypto++ (gf2n.cpp) up to version 8.9.0. The vulnerability allows a DoS (application crash) via DER-encoded public-key data for an F(2^m) curve when the polynomial term degrees are not strictly decreasing. Multiple advisories (OpenSUSE, SUSE, Astra Linux, Nessus references)...

UBUNTU-CVE-2022-48570

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 remov...

SUSE CVE-2016-9939

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 b...

FreeBSD : cryptopp -- ElGamal implementation allows plaintext recovery (7695b0af-958f-11ec-9aa3-4ccc6adda413)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 7695b0af-958f-11ec-9aa3-4ccc6adda413 advisory. - The ElGamal implementation in Crypto++ through 8.5 allows plaintext recovery because, during...

CVE-2021-43398

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...
