Corrected 2026-10-23 - see C3-B691-01; the original statements below are kept for history and are superseded where the correction says so. sox_ng (a4a14b4f) is a hard fork of sox-14.4.2 hosted on Codeberg and by default installs as sox_ng/libsox_ng, not replacing 'sox' unless built with --enable-replace, so scripts calling 'sox' may still invoke the original.

Curator correction 2026-10-23 (discovery audit record C3-B691-01; sources re-fetched 2026-10-23, excerpts re-located by curator GET): Problem. Candidate R5-03 states, for sox_ng issue 877, that a participant reports the PoC crashes current sox_ng and that the maintainer says he will fix it (2026-10-21). Conditions. Applies when deciding whether sox_ng is a safe replacement for sox on untrusted WAV input. Method. Re-read the issue and all comments via the Codeberg API on 2026-10-23. Findings: (1) a participant (mavit, 2026-10-20) did crash git sox_ng under AddressSanitizer in lsx_ms_adpcm_block_expand_i, so the crash claim is supported; his 2026-10-23 comment says the reproduction needed a modified src/Makefile; (2) no maintainer comment promising a fix appears in the thread; the maintainer's first reply (2026-10-19) was 'I don't know. Is it?' and on 2026-10-22 he said the report's quoted code (wav_ms_adpcm_fmt, lsx_read_fields) is not in src/wav.c and he had found no file that provokes the error; (3) another participant (2026-10-23) explains the report targets a different SoX lineage with changes absent from sox_ng, and points to wav.c:1051 startread_wav() as the corresponding sox_ng code. Failure modes. Treating sox_ng as either clean or confirmed-fixed is unsupported: exposure is reproduced by one third party under sanitizer but the report's fix text does not map onto sox_ng and the issue is still open. Limitations. Thread may have been edited after this read; the claimed 2026-10-21 maintainer statement may have been in a deleted or edited item, which I cannot see. Version/date. Issue state open, last updated 2026-10-23T17:58+02:00; sox_ng latest tag 14.8.1 (2026-08-29); main head 1abe5b9 (2026-10-18).

Curator qualifications: Release cadence, -R repeatability, per-release output changes, Windows binary provenance episodes, threading defaults and licence presentation (F3-F9) not reinspected. CVE and PoC statements (F6) are producer-reported security information; not verified, not to be published as an assessment. Original SoX release history (F0) not reinspected. Source/doc text only; nothing built or run.

Limitations: Source/doc text only; nothing built or run.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
