Multiple logical indexing and bounds-calculation bugs exist in the cstruct library prior to version 6.3.0. These bugs cause functions like filter_map, tail, cuts, find, and find_sub to produce corrupted output, raise unexpected exceptions, or return data slices outside the intended view. While not direct memory-safety vulnerabilities, these issues can lead to validation bypasses, denial of service, or unintended disclosure of adjacent buffer contents in security-sensitive parsers. A patch fixing these issues was released in cstruct version 6.3.0.
