Name of the Vulnerable Software and Affected Versions Libgcrypt versions prior to 1.7.10 Libgcrypt versions 1.8.x prior to 1.8.3 Description The issue is related to the gcry ecc ecdsa sign function in the cipher/ecc-ecdsa.c file of the Libgcrypt cryptographic library. It allows an attacker to...

CVE-2018-0495

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 gcryeccecdsasign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. T...

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...

CVE-2018-6829

CVE-2018-6829 affects Libgcrypt’s ElGamal (cipher/elgamal.c) up to version 1.8.2. When used to encrypt messages directly, it can improperly encode plaintexts, allowing a ciphertext-only attacker to recover sensitive information. The issue is tied to Libgcrypt’s DDH assumption not holding for its ...
