txscript: most-fixed (9 issues). Treat as high-risk during review.
35 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.
Denial of Service: Recursive self-referential calling during JSON marshaling of StringOrArray values triggers stack exhaustion and immediate process crashes. This pattern recurred and required structural casting to prevent infinite recursion.
Consensus Bypass: Deviations in block validation rules, such as BIP30 validation height logic and ancestral activation checks, introduce severe consensus-divergence risks on alternate blockchain forks.
Denial of Service: Input parsing routines in cryptographic libraries suffer from lack of bounds checks on arrays, leading to out-of-bounds writes in SetByteSlice and signature parser crashes.
