{"id":"DEBIAN-CVE-2026-37555","details":"An issue was discovered in libsndfile 1.2.2 IMA ADPCM codec. The AIFF code path (line 241) was fixed with (sf_count_t) cast, but the WAV code path (line 235) and close path (line 167) were not. When samplesperblock (int) * blocks (int) exceeds INT_MAX, the 32-bit multiplication overflows before being assigned to sf.frames (sf_count_t/int64). With samplesperblock=50000 and blocks=50000, the product 2500000000 overflows to -1794967296. This causes incorrect frame count leading to heap buffer overflow or denial of service. Both values come from the WAV file header and are attacker-controlled. This issue was discovered after an incomplete fix for CVE-2022-33065.","modified":"2026-09-14T17:03:09.746606933Z","published":"2026-04-29T16:16:23.410Z","upstream":["CVE-2026-37555"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-37555"}],"affected":[{"package":{"name":"libsndfile","ecosystem":"Debian:12","purl":"pkg:deb/debian/libsndfile?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.0-1","1.2.0-1+deb12u1","1.2.2-1","1.2.2-1+hurd.1","1.2.2-1+hurd.2","1.2.2-1+hurd.3","1.2.2-2","1.2.2-3","1.2.2-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-37555.json"}},{"package":{"name":"libsndfile","ecosystem":"Debian:13","purl":"pkg:deb/debian/libsndfile?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.2-2","1.2.2-2+deb13u1","1.2.2-3","1.2.2-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-37555.json"}},{"package":{"name":"libsndfile","ecosystem":"Debian:14","purl":"pkg:deb/debian/libsndfile?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.2-2","1.2.2-3","1.2.2-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-37555.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
