Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Corruption: Inadequate verification of array argument indexes (specifically for `c_array_length_in_arg`) can allow out-of-bounds array indexing, potentially causing memory corruption or arbitrary memory reads during libffi-based method calls.
Memory Corruption: Inconsistent deallocation paths for argument and return value descriptors can result in resource leaks or catastrophic double-free conditions when parsing objective-c signatures.
Memory Corruption: Failing to account for the NUL terminator during Python-to-C-array byte transitions using `dataWithBytes:length:` creates out-of-bounds read and buffer overflow risks.
