{"id":"CVE-2026-111132","summary":"GNOME libgxps through 0.3.2 Heap Out-of-Bounds Read via path_geometry_start_element","details":"GNOME libgxps through 0.3.2 contains a heap out-of-bounds read in path_geometry_start_element() that allows attackers to read past allocations via crafted PolyBezierSegment or PolyQuadraticBezierSegment Points attributes. Attackers can supply a point count not divisible by three or two in a crafted XPS document to crash consumers like Evince and render adjacent heap memory into output.","modified":"2026-10-16T10:46:28.176753559Z","published":"2026-10-15T18:57:27.144Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111132.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-125"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111132.json"},{"type":"WEB","url":"https://gitlab.gnome.org"},{"type":"PACKAGE","url":"https://gitlab.gnome.org/GNOME/libgxps"},{"type":"ARTICLE","url":"https://gitlab.gnome.org/GNOME/libgxps/-/blob/f5027ed09c767e8a02e652fbc77dcea79e19e10d/libgxps/gxps-path.c#L776-L785"},{"type":"ARTICLE","url":"https://gitlab.gnome.org/GNOME/libgxps/-/blob/f5027ed09c767e8a02e652fbc77dcea79e19e10d/libgxps/gxps-path.c#L832-L848"},{"type":"ARTICLE","url":"https://hackmd.io/@haind-pwn/libgxps-poly-segment-points-arity-oob-read"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111132"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/gnome-libgxps-through-0.3.2-heap-out-of-bounds-read-via-path-geometry-start-element"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://gitlab.gnome.org/gnome/libgxps","events":[{"introduced":"0"},{"last_affected":"f5027ed09c767e8a02e652fbc77dcea79e19e10d"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"0.3.2"}],"source":"AFFECTED_FIELD"}}],"versions":["0.3.2","0.3.1","0.3.0","0.2.5","0.2.4","0.2.3.2","0.2.3.1","0.2.3","0.2.2","0.2.1","0.2.0","0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-111132.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
