Libgcrypt before 1.12.2 mishandles Dilithium signing. Writes to a static array lack a bounds check but do not use attacker-controlled data.
Libgcrypt before 1.12.2 sometimes allows a heap-based buffer overflow and denial of service via crafted ECDH ciphertext to gcry_pk_decrypt.
A timing-based side-channel flaw was found in libgcrypt's RSA implementation. This issue may allow a remote attacker to initiate a Bleichenbacher-style attack, which can lead to the decryption of RSA ciphertexts.
