| CVE-2021-33560 | 4 Debian, Fedoraproject, Gnupg and 1 more | 8 Debian Linux, Fedora, Libgcrypt and 5 more | 2022-07-25 | 5.0 MEDIUM | 7.5 HIGH |
| 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. This, for example, affects use of ElGamal in OpenPGP. | |||||
| CVE-2021-3345 | 2 Gnupg, Oracle | 2 Libgcrypt, Communications Billing And Revenue Management | 2022-04-26 | 7.2 HIGH | 7.8 HIGH |
| _gcry_md_block_write in cipher/hash-common.c in Libgcrypt version 1.9.0 has a heap-based buffer overflow when the digest final function sets a large count value. It is recommended to upgrade to 1.9.1 or later. | |||||
| CVE-2018-6829 | 1 Gnupg | 1 Libgcrypt | 2020-01-15 | 5.0 MEDIUM | 7.5 HIGH |
| 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). The Decisional Diffie-Hellman (DDH) assumption does not hold for Libgcrypt's ElGamal implementation. | |||||
| CVE-2017-0379 | 2 Debian, Gnupg | 2 Debian Linux, Libgcrypt | 2019-01-16 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
