{"id":"DEBIAN-CVE-2026-1485","details":"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.","modified":"2026-09-14T17:02:46.665264358Z","published":"2026-01-27T14:15:56.223Z","upstream":["CVE-2026-1485"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-1485"}],"affected":[{"package":{"name":"glib2.0","ecosystem":"Debian:12","purl":"pkg:deb/debian/glib2.0?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.74.6-2+deb12u9"}]}],"versions":["2.74.6-2","2.74.6-2+deb12u1","2.74.6-2+deb12u2","2.74.6-2+deb12u3","2.74.6-2+deb12u4","2.74.6-2+deb12u5","2.74.6-2+deb12u6","2.74.6-2+deb12u7","2.74.6-2+deb12u8"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-1485.json"}},{"package":{"name":"glib2.0","ecosystem":"Debian:13","purl":"pkg:deb/debian/glib2.0?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.84.4-3~deb13u3"}]}],"versions":["2.84.3-1","2.84.4-1","2.84.4-2","2.84.4-3~deb13u1","2.84.4-3~deb13u2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-1485.json"}},{"package":{"name":"glib2.0","ecosystem":"Debian:14","purl":"pkg:deb/debian/glib2.0?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.86.3-5"}]}],"versions":["2.84.3-1","2.84.4-1","2.84.4-2","2.84.4-3","2.84.4-3~deb13u1","2.84.4-3~deb13u2","2.84.4-3~deb13u3","2.84.4-3~deb13u4","2.84.4-3~deb13u5","2.85.1-1","2.85.1-2","2.85.2-2","2.85.3-1","2.85.4-1","2.86.0-1","2.86.0-2","2.86.0-3","2.86.0-4","2.86.0-5","2.86.0-6","2.86.0-7","2.86.1-1","2.86.1-2","2.86.2-1","2.86.3-1","2.86.3-2","2.86.3-3","2.86.3-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-1485.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L"}]}
