{"id":"OESA-2026-4693","summary":"zvbi security update","details":"The ZVBI library provides functions to read from Linux V4L, V4L2 and FreeBSD BKTR raw VBI capture devices, from Linux DVB devices and from a VBI proxy to share V4L and V4L2 VBI devices between multiple applications. It can demodulate raw to sliced VBI data in software, with support for a wide range of formats, has functions to decode several popular services including Teletext and Closed Caption, a Teletext cache with search function, various text export and rendering functions.\r\n\r\nSecurity Fix(es):\n\nlibzvbi 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.(CVE-2026-110654)","modified":"2026-11-04T14:00:05.232662160Z","published":"2026-11-04T13:54:33Z","upstream":["CVE-2026-110654"],"database_specific":{"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4693"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110654"}],"affected":[{"package":{"name":"zvbi","ecosystem":"openEuler:24.03-LTS-SP3","purl":"pkg:rpm/openEuler/zvbi&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.2.44-3.oe2403sp3"}]}],"ecosystem_specific":{"x86_64":["zvbi-0.2.44-3.oe2403sp3.x86_64.rpm","zvbi-debuginfo-0.2.44-3.oe2403sp3.x86_64.rpm","zvbi-debugsource-0.2.44-3.oe2403sp3.x86_64.rpm","zvbi-devel-0.2.44-3.oe2403sp3.x86_64.rpm","zvbi-help-0.2.44-3.oe2403sp3.x86_64.rpm"],"aarch64":["zvbi-0.2.44-3.oe2403sp3.aarch64.rpm","zvbi-debuginfo-0.2.44-3.oe2403sp3.aarch64.rpm","zvbi-debugsource-0.2.44-3.oe2403sp3.aarch64.rpm","zvbi-devel-0.2.44-3.oe2403sp3.aarch64.rpm","zvbi-help-0.2.44-3.oe2403sp3.aarch64.rpm"],"src":["zvbi-0.2.44-3.oe2403sp3.src.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-4693.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N"}]}
