{"id":"DEBIAN-CVE-2026-1940","details":"An incomplete fix for CVE-2024-47778 allows an out-of-bounds read in gst_wavparse_adtl_chunk() function. The patch added a size validation check lsize + 8 \u003e size, but it does not account for the GST_ROUND_UP_2(lsize) used in the actual offset calculation. When lsize is an odd number, the parser advances more bytes than validated, causing OOB read.","modified":"2026-09-01T16:06:33.621059564Z","published":"2026-03-23T22:16:25.043Z","upstream":["CVE-2026-1940"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-1940"}],"affected":[{"package":{"name":"gst-plugins-good1.0","ecosystem":"Debian:12","purl":"pkg:deb/debian/gst-plugins-good1.0?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22.0-5","1.22.0-5+deb12u1","1.22.0-5+deb12u2","1.22.0-5+deb12u3","1.22.1-1","1.22.10-1","1.22.3-1","1.22.3-2","1.22.4-1","1.22.5-1","1.22.6-1","1.22.7-1","1.22.8-1","1.22.8-2","1.22.8-3","1.22.9-1","1.23.1-1","1.23.2-1","1.23.90-1","1.24.0-1","1.24.1-1","1.24.1-2","1.24.10-1","1.24.11-1","1.24.11-2","1.24.11-3","1.24.11-4","1.24.11-5","1.24.12-1","1.24.2-1","1.24.3-1","1.24.4-1","1.24.5-1","1.24.6-1","1.24.7-1","1.24.8-1","1.24.9-1","1.25.1-1","1.25.1-2","1.25.1-3","1.25.50-1","1.25.90-1","1.25.90-2","1.26.0-1","1.26.1-1","1.26.10-1","1.26.2-1","1.26.3-1","1.26.4-1","1.26.5-1","1.26.5-2","1.26.5-2+hurd.1","1.26.5-3","1.26.6-1","1.26.7-1","1.26.8-1","1.26.9-1","1.27.1-1","1.27.2-1","1.27.50-1","1.27.50-2","1.27.90-1","1.28.0-1","1.28.1-1","1.28.2-1","1.28.2-2","1.28.2-3","1.28.2-4","1.28.3-1","1.28.4-1","1.28.5-1","1.28.6-1","1.29.1-1","1.29.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-1940.json"}},{"package":{"name":"gst-plugins-good1.0","ecosystem":"Debian:13","purl":"pkg:deb/debian/gst-plugins-good1.0?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.26.2-1+deb13u2"}]}],"versions":["1.26.2-1","1.26.2-1+deb13u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-1940.json"}},{"package":{"name":"gst-plugins-good1.0","ecosystem":"Debian:14","purl":"pkg:deb/debian/gst-plugins-good1.0?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.28.1-1"}]}],"versions":["1.26.10-1","1.26.2-1","1.26.3-1","1.26.4-1","1.26.5-1","1.26.5-2","1.26.5-2+hurd.1","1.26.5-3","1.26.6-1","1.26.7-1","1.26.8-1","1.26.9-1","1.27.1-1","1.27.2-1","1.27.50-1","1.27.50-2","1.27.90-1","1.28.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-1940.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"}]}
