{"id":"DEBIAN-CVE-2026-0988","details":"A flaw was found in glib. Missing validation of offset and count parameters in the g_buffered_input_stream_peek() function can lead to an integer overflow during length calculation. When specially crafted values are provided, this overflow results in an incorrect size being passed to memcpy(), triggering a buffer overflow. This can cause application crashes, leading to a Denial of Service (DoS).","modified":"2026-10-01T03:00:32.910596130Z","published":"2026-01-21T12:15:55.560Z","upstream":["CVE-2026-0988"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-0988"}],"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-2026-0988.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-2026-0988.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-2026-0988.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}
