CVE-2014-5270
Libgcrypt prior to 1.5.4, as used in GnuPG and other products, does not properly perform ciphertext normalization and ciphertext randomization, which makes it easier for physically proximate malicious users to conduct key-extraction attacks by leveraging the ability to collect vo...

CVE-2017-9526
In Libgcrypt prior to 1.7.7, an attacker who learns the EdDSA session key (from side-channel observation during the signing process) can easily recover the long-term secret key. 1.7.7 makes a cipher/ecc-eddsa.c change to store this session key in secure memory, to ensure that con...

CVE-2018-6829
cipher/elgamal.c in Libgcrypt up to and including 1.8.2, when used to encrypt messages directly, improperly encodes plaintexts, which allows malicious users to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertex...

CVE-2021-40528
The ElGamal implementation in Libgcrypt prior to 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 p...

CVE-2019-12904
In Libgcrypt 1.8.4, the C implementation of AES is vulnerable to a flush-and-reload side-channel attack because physical addresses are available to other processes. (The C implementation is used on platforms where an assembly-language implementation is unavailable.) NOTE: the ven...

CVE-2017-0379
Libgcrypt prior to 1.8.1 does not properly consider Curve25519 side-channel attacks, which makes it easier for malicious users to discover a secret key, related to cipher/ecc.c and mpi/ec.c.

CVE-2021-3345
_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-2015-0837
The mpi_powm function in Libgcrypt prior to 1.6.3 and GnuPG prior to 1.4.19 allows malicious users to obtain sensitive information by leveraging timing differences when accessing a pre-computed table during modular exponentiation, related to a "Last-Level Cache Side-Channel ...

CVE-2014-3591
Libgcrypt prior to 1.6.3 and GnuPG prior to 1.4.19 does not implement ciphertext blinding for Elgamal decryption, which allows physically proximate malicious users to obtain the server's private key by determining factors using crafted ciphertext and the fluctuations in the ...

CVE-2017-7526
libgcrypt before version 1.7.8 is vulnerable to a cache side-channel attack resulting into a complete break of RSA-1024 while using the left-to-right method for computing the sliding-window expansion. The same attack is believed to work on RSA-2048 with moderately more computatio...
