4.3
CVSSv2
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...

CVSSv2
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...

CVSSv2
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.

CVSSv2
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...

CVSSv2
CVE-2015-7511
Libgcrypt prior to 1.6.5 does not properly perform elliptic-point curve multiplication during decryption, which makes it easier for physically proximate malicious users to extract ECDH keys by measuring electromagnetic emanations.

CVSSv2
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...
