2021-01-29 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. Libgcrypt, Communications_billing_and_revenue_management 7.8
2021-06-08 CVE-2021-33560 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. Debian_linux, Fedora, Libgcrypt, Communications_cloud_native_core_binding_support_function, Communications_cloud_native_core_network_function_cloud_native_environment, Communications_cloud_native_core_network_repository_function, Communications_cloud_native_core_network_slice_selection_function, Communications_cloud_native_core_service_communication_proxy 7.5
2021-09-06 CVE-2021-40528 The ElGamal implementation in Libgcrypt before 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 public key, and the sender's ephemeral exponents can lead to a cross-configuration attack against OpenPGP. Libgcrypt 5.9
2019-06-20 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 vendor's position is that the issue report cannot be validated because there is no description of an attack Libgcrypt, Leap 5.9
2016-04-19 CVE-2015-7511 Libgcrypt before 1.6.5 does not properly perform elliptic-point curve multiplication during decryption, which makes it easier for physically proximate attackers to extract ECDH keys by measuring electromagnetic emanations. Ubuntu_linux, Debian_linux, Libgcrypt 2.0
2016-12-13 CVE-2016-6313 The mixing functions in the random number generator in Libgcrypt before 1.5.6, 1.6.x before 1.6.6, and 1.7.x before 1.7.3 and GnuPG before 1.4.21 make it easier for attackers to obtain the values of 160 bits by leveraging knowledge of the previous 4640 bits. Ubuntu_linux, Debian_linux, Gnupg, Libgcrypt 5.3
2017-06-11 CVE-2017-9526 In Libgcrypt before 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 constant-time point operations are used in the MPI library. Libgcrypt 5.9
2017-08-29 CVE-2017-0379 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. Debian_linux, Libgcrypt 7.5
2018-06-13 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 _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host. Ubuntu_linux, Debian_linux, Libgcrypt, Traffic_director, Ansible_tower, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_workstation 4.7
2018-07-26 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 computation. This side-channel requires that attacker can run arbitrary software on the hardware where the private RSA key is used. Ubuntu_linux, Debian_linux, Libgcrypt 6.8
