概要
Botan: Heap Buffer Over-read in SM2 Decryption via Undersized C3 Hash Field
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
Botan is a C++ cryptography library. From version 2.3.0 to before version 3.11.0, during SM2 decryption, the code that checked the authentication code value (C3) failed to check that the encoded value was of the expected length prior to comparison. An invalid ciphertext can cause a heap over-read of up to 31 bytes, resulting in a crash or potentially other undefined behavior. This issue has been patched in version 3.11.0.
