| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2021-09-06 | CVE-2021-40528 | Use of a Broken or Risky Cryptographic Algorithm vulnerability in Gnupg Libgcrypt The ElGamal implementation in Libgcrypt before 1.9.4 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. | 5.9 |
| 2021-06-08 | CVE-2021-33560 | Information Exposure Through Discrepancy vulnerability in multiple products Libgcrypt before 1.8.8 and 1.9.x before 1.9.3 mishandles ElGamal encryption because it lacks exponent blinding to address a side-channel attack against mpi_powm, and the window size is not chosen appropriately. | 7.5 |
| 2018-06-13 | CVE-2018-0495 | Information Exposure Through Discrepancy vulnerability in multiple products Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. | 4.7 |
| 2018-02-07 | CVE-2018-6829 | Use of a Broken or Risky Cryptographic Algorithm vulnerability in Gnupg Libgcrypt cipher/elgamal.c in Libgcrypt through 1.8.2, when used to encrypt messages directly, improperly encodes plaintexts, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). | 5.0 |
| 2017-08-29 | CVE-2017-0379 | Information Exposure vulnerability in multiple products Libgcrypt before 1.8.1 does not properly consider Curve25519 side-channel attacks, which makes it easier for attackers to discover a secret key, related to cipher/ecc.c and mpi/ec.c. | 7.5 |
