Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Corruption: Inadequate parameter validation (data, key, IV, and state) prior to calling low-level operations can lead to out-of-bounds memory access during cryptographic execution. This risk is critical as it directly exposes the underlying C implementations of ige256, ctr256, and cbc256 to memory corruption.
Denial of Service: Flawed index decrements in cryptographic block processing can result in infinite loops during execution. A failure in the loop terminal condition (such as in counter state incrementation) directly triggers application hangs and denial of service.
