Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in the SM2 decryption process due to improper validation of the encoded C3 hash field length prior to comparison. An attacker can cause a heap buffer over-read, potentially leading to a crash or other undefined...

CVE-2026-32877

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 o...
