22 high-severity fixes in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Cryptographic Issues: The implementation failed to correctly validate authentication tags before releasing plaintext or during finalization, which fully compromises the authenticity guarantees of the AEAD mode. This occurred across both CCM and GCM decryptions.
Cryptographic Issues: Validation of the AES Initialization Vector (IV) length was incorrectly tied to the key size rather than the cipher block size, potentially leading to weakened cryptosystems or runtime errors.
Memory Corruption: An incorrect byte length calculation using type sizes inside UnsafeMutablePointer allocations could trigger out-of-bounds memory accesses during byte-array conversions.
