CVE-2026-32877

A flaw was found in Botan, a C++ cryptography library. During SM2 decryption, the library failed to validate the length of the authentication code value C3 before comparison. A remote attacker could exploit this by providing a specially crafted invalid ciphertext, leading to a heap over-read of u...

CVE-2026-32883

A flaw was found in Botan. A remote attacker could exploit a vulnerability in the X509 path validation process where the signature of Online Certificate Status Protocol OCSP responses was not verified. This omission allows an attacker to provide forged OCSP responses, potentially leading to the...

Improper Verification of Cryptographic Signature

Overview Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature in the OCSP response validation process. An attacker can bypass certificate revocation checks by providing a forged OCSP response, potentially enabling man-in-the-middle attacks...

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...
