this flaw, an attacker needs to capture ciphertext encrypted by the `GOSTCTR` implementation where the `G3413CTRBlockCipher` processed more than 255 blocks of data, resulting in keystream reuse. An attack typically requires capturing these overlapping ciphertexts to perform cryptanalysis and uncover the underlying data.\nThe primary impact of this vulnerability is the potential loss of confidentiality for data encrypted by the `GOSTCTR` implementation. This can compromise encrypted communications or sensitive stored data by allowing an attacker to fully recover the plaintext.", "threat_severity": "Important"}
