{"id":"JLSEC-2026-1245","summary":"A flaw was found in GLib. A buffer over-read can occur in the g_regex_replace function when used...","details":"A flaw was found in GLib. A buffer over-read can occur in the `g_regex_replace` function when used with the `G_REGEX_RAW` compile flag and case-change replacement escapes because the `string_append` function processes matched substrings using UTF-8 functions that assume valid UTF-8 input, even when the string is treated as raw bytes. This vulnerability can cause a minor information disclosure of 1-5 bytes and a denial of service when the buffer over-read crosses a page boundary.","modified":"2026-08-11T14:14:15.903216111Z","published":"2026-08-11T13:55:26.657Z","upstream":["CVE-2026-58012","EUVD-2026-40314","GHSA-vwg8-37h9-g38g"],"database_specific":{"sources":[{"imported":"2026-08-11T06:49:24.088Z","modified":"2026-08-03T06:16:38.590Z","published":"2026-06-30T13:19:17.330Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-58012","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58012","database_specific":{"status":"Modified"},"id":"CVE-2026-58012"},{"id":"GHSA-vwg8-37h9-g38g","imported":"2026-08-11T06:49:24.610Z","modified":"2026-08-03T06:32:44Z","published":"2026-06-30T15:30:45Z","url":"https://api.github.com/advisories/GHSA-vwg8-37h9-g38g","html_url":"https://github.com/advisories/GHSA-vwg8-37h9-g38g"},{"id":"EUVD-2026-40314","imported":"2026-08-11T06:49:24.356Z","modified":"2026-08-03T04:04:35Z","published":"2026-06-30T12:57:21Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-40314","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-40314"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:49512"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-58012"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2492247"},{"type":"WEB","url":"https://github.com/advisories/GHSA-vwg8-37h9-g38g"},{"type":"WEB","url":"https://gitlab.gnome.org/GNOME/glib/-/issues/3918"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58012"}],"affected":[{"package":{"name":"Glib_jll","ecosystem":"Julia","purl":"pkg:julia/Glib_jll?uuid=7746bdde-850d-59dc-9ae8-88ece973131d"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.88.3+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1245.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:L/I:N/A:H"}]}
