{"schemaVersion":3,"id":"CVE-2026-1485","aliases":["UBUNTU-CVE-2026-1485","DEBIAN-CVE-2026-1485"],"status":"published","duplicateOf":null,"title":null,"description":"A flaw was found in Glib's content type parsing logic. This buffer underflow vulnerability occurs because the length of a header line is stored in a signed integer, which can lead to integer wraparound for very large inputs. This results in pointer underflow and out-of-bounds memory access. Exploitation requires a local user to install or process a specially crafted treemagic file, which can lead to local denial of service or application instability.","dates":{"published":"2026-01-27T13:43:18.098Z","modified":"2026-03-18T16:44:23.593Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":2.8,"severity":"low","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":2.8,"severity":"low","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
