Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Multiple fixes addressed integer overflow in size computations for combinators like count, length_count, many0, many1, many_till, many_m_n, fold_many. Overflow can lead to incorrect buffer sizes, resource exhaustion, or logic bypasses.
Denial of Service: Chain!, tuple!, and do_parse combinators had unchecked additions on consumed bytes, risking overflow that could cause incorrect parsing or DoS.
Denial of Service: Bits-to-bytes size calculation used unchecked multiplication, allowing overflow that could lead to resource exhaustion.
