Comment 1 Ben Beasley 2026-03-04 05:50:02 UTC

See https://www.cve.org/CVERecord?id=CVE-2026-29022. This is fixed in dr_wav 0.14.5. Fedora 42 has 0.13.17, https://bodhi.fedoraproject.org/updates/FEDORA-2024-b369b28c3c.

Since there were significant incompatible changes from 0.13.17 to 0.14.x (and the other two dr_* libraries had incompatible changes at the same time), updating would require an Updates Policy exception and significant coordination. This is not the only potentially security-relevant issue fixed since dr_flac 0.12.x / dr_mp3 0.6.x / dr_wav 0.13.x. It is just the only one that has been assigned a CVE, as far as I know.

Backporting the fix for this CVE in particular, https://github.com/mackron/dr_libs/commit/8a7258cc66b49387ad58cc5b81568982a3560d49, does seam feasible, so I will at least do that.
