CVE-2018-0495

CVE-2018-0495 affects Libgcrypt prior to 1.7.10 and 1.8.x prior to 1.8.3. The root cause is a memory-cache side-channel (ROHNP) in the ECDSA signing path (_gcry_ecc_ecdsa_sign in cipher/ecc-ecdsa.c), enabling an attacker with local or co-resident VM access to recover ECDSA private keys. Mitigatio...

CVE-2018-6829

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...

Libgcrypt Information Disclosure Vulnerability (CNVD-2018-05552)

Libgcrypt is a cryptographic library developed as an independent module of GnuPG. An information disclosure vulnerability exists in Libgcrypt versions 1.8.2 and earlier. The vulnerability arises because cipher/elgamal.c in Libgcrypt improperly encodes plaintext when used to directly encrypt...
