A buffer over-read can occur in `g_io_channel_read_line_backend()` in the giochannel.c file when a custom line terminator with a length greater than one is set, causing memcmp to read past the GString buffer. This vulnerability can cause a minor information disclosure of 7 bytes or a denial of service when the buffer over-read crosses a page boundary.","modified":"2026-08-11T14:14:16.107939038Z","published":"2026-08-11T13:55:26.657Z","upstream":["CVE-2026-58013","EUVD-2026-40315","GHSA-4x46-h598-64qr"],"database_specific":{"sources":[{"database_specific":{"status":"Modified"},"id":"CVE-2026-58013","imported":"2026-08-11T06:49:24.108Z","modified":"2026-08-03T06:16:38.747Z","published":"2026-06-30T13:19:17.457Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-58013","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58013"},{"modified":"2026-08-03T06:32:44Z","published":"2026-06-30T15:30:45Z","url":"https://api.github.com/advisories/GHSA-4x46-h598-64qr","html_url":"https://github.com/advisories/GHSA-4x46-h598-64qr","id":"GHSA-4x46-h598-64qr","imported":"2026-08-11T06:49:25.586Z"},{"html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-40315","id":"EUVD-2026-40315","imported":"2026-08-11T06:49:24.330Z","modified":"2026-08-03T04:04:39Z","published":"2026-06-30T12:57:34Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-40315"}],"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-2026-58013"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2492248"},{"type":"WEB","url":"https://github.com/advisories/GHSA-4x46-h598-64qr"},{"type":"WEB","url":"https://gitlab.gnome.org/GNOME/glib/-/issues/3925"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58013"}],"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-2026-1246.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"}]}
