Examples include any GNOME or GTK+ based application that uses Pango for text layout, as this internally uses FriBidi for bidirectional text layout. For example, the attacker can construct a crafted text file to be opened in GEdit, or a crafted IRC message to be viewed in HexChat.","modified":"2026-07-23T22:30:16.189481456Z","published":"2025-10-20T22:55:27.993Z","upstream":["CVE-2019-18397"],"database_specific":{"license":"CC-BY-4.0","sources":[{"published":"2019-11-13T14:15:10.287Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2019-18397","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2019-18397","database_specific":{"status":"Modified"},"id":"CVE-2019-18397","imported":"2026-07-17T20:40:32.487Z","modified":"2026-06-17T02:24:58.563Z"}]},"references":[{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2019:4326"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2019:4361"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2020:0291"},{"type":"WEB","url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=944327"},{"type":"WEB","url":"https://github.com/fribidi/fribidi/commit/034c6e9a1d296286305f4cfd1e0072b879f52568"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TFS3N6KKXPI6ATDNEUFRSLX7R6BOBNIP/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/W5UJRTG32FDNI7T637Q6PZYL3UCRR5HR/"},{"type":"WEB","url":"https://marc.info/?l=oss-security&m=157322128105807&w=2"},{"type":"WEB","url":"https://security-tracker.debian.org/tracker/CVE-2019-18397"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202003-41"}],"affected":[{"package":{"name":"FriBidi_jll","ecosystem":"Julia","purl":"pkg:julia/FriBidi_jll?uuid=559328eb-81f9-559d-9380-de523a88c83c"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.0.10+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2025/JLSEC-2025-169.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V2","score":"AV:N/AC:M/Au:N/C:P/I:P/A:P"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
