Codebase Audit Report: Findings & Remediation

[segin]

Performed a comprehensive codebase audit focusing on security, correctness, and operational risks.

Key Deliverables:

• Executive Summary: Health score 65/100. Top risks include Critical UB in FLAC decoder and build system fragility.
• Findings: Identified 5 key issues including an Integer Overflow in SampleReconstructor.cpp, logic errors in audio.cpp, and missing compiler security flags.
• Remediation: A patch file is provided to fix the Critical UB and apply hardening flags to configure.ac.

Notes:

• Runtime verification was limited due to missing legacy dependencies (SDL 1.2, TagLib) in the environment.
• Static analysis and code review were the primary methods used.
• The repository source code was left unmodified; fixes are provided in REMEDIATION.patch.
