{"id":"DEBIAN-CVE-2026-110654","details":"libzvbi through 0.2.45 contains an out-of-bounds write vulnerability in the Teletext decoder that allows attackers to corrupt memory by supplying unvalidated DRCS pixel-mode values in X/28/3 packets. Attackers can send a crafted Teletext stream decoded via vbi_decode with every slot set to DRCS_MODE_6_5_4, causing convert_drcs to overflow chars[48][60] and crash the application.","modified":"2026-10-17T12:00:07.613759611Z","published":"2026-10-14T16:17:42.070Z","upstream":["CVE-2026-110654"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-110654"}],"affected":[{"package":{"name":"zvbi","ecosystem":"Debian:12","purl":"pkg:deb/debian/zvbi?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.2.41-1","0.2.41-1+deb12u1","0.2.41-2","0.2.42-1","0.2.42-1.1","0.2.42-1.2","0.2.42-1.2~exp1","0.2.42-2","0.2.43-1","0.2.43-1+hurd.1","0.2.43-2","0.2.44-1","0.2.44-2","0.2.45-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110654.json"}},{"package":{"name":"zvbi","ecosystem":"Debian:13","purl":"pkg:deb/debian/zvbi?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.2.44-1","0.2.44-2","0.2.45-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110654.json"}},{"package":{"name":"zvbi","ecosystem":"Debian:14","purl":"pkg:deb/debian/zvbi?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.2.44-1","0.2.44-2","0.2.45-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110654.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H"}]}
