When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink, it incorrectly also creates the target of the symlink as an empty file, which could conceivably have security relevance if the symlink is attacker-controlled. (If the path is a symlink to a file that already exists, then the contents of that file correctly remain unchanged.)","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-59"],"references":["https://gitlab.gnome.org/GNOME/glib/-/issues/2325","https://lists.debian.org/debian-lts-announce/2022/06/msg00006.html","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6RXTD5HCP2K4AAUSWWZTBKQNHRCTAEOF/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ICUTQPHZNZWX2DZR46QFLQZRHVMHIILJ/","https://security.gentoo.org/glsa/202107-13"],"products":["broadcom:brocade_fabric_operating_system_firmware","debian:debian_linux","fedoraproject:fedora","gnome:glib"],"source":"nvd","synced_at":"2026-10-19T21:15:50.279857260+00:00"},"epss":{"cve":"CVE-2021-28153","score":0.02708,"percentile":0.85861,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
