{"id":"CVE-2019-18397","details":"A buffer overflow in the fribidi_get_par_embedding_levels_ex() function in lib/fribidi-bidi.c of GNU FriBidi through 1.0.7 allows an attacker to cause a denial of service or possibly execute arbitrary code by delivering crafted text content to a user, when this content is then rendered by an application that uses FriBidi for text layout calculations. 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":"2026-05-16T12:02:54.116659175Z","published":"2019-11-13T14:15:10.287Z","related":["SUSE-SU-2021:1655-1","openSUSE-SU-2021:0763-1","openSUSE-SU-2021:1655-1","openSUSE-SU-2024:10772-1"],"database_specific":{"unresolved_ranges":[{"source":"CPE_FIELD","vendor_product":"debian:debian_linux","cpes":["cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*","cpe:2.3:o:debian:debian_linux:8.0:*:*:*:*:*:*:*","cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"10.0"},{"last_affected":"8.0"},{"last_affected":"9.0"},{"last_affected":"10.0"}]}]},"references":[{"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":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4326"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4361"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2020:0291"},{"type":"ADVISORY","url":"https://marc.info/?l=oss-security&m=157322128105807&w=2"},{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2019-18397"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202003-41"},{"type":"REPORT","url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=944327"},{"type":"FIX","url":"https://github.com/fribidi/fribidi/commit/034c6e9a1d296286305f4cfd1e0072b879f52568"}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
