{"id":"UBUNTU-CVE-2026-111132","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":"2026-10-17T12:59:52.111479593Z","published":"2026-10-16T00:00:00Z","upstream":["CVE-2026-111132"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-111132"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-111132"},{"type":"REPORT","url":"https://gitlab.gnome.org/GNOME/libgxps"},{"type":"REPORT","url":"https://gitlab.gnome.org/GNOME/libgxps/-/blob/f5027ed09c767e8a02e652fbc77dcea79e19e10d/libgxps/gxps-path.c#L776-L785"},{"type":"REPORT","url":"https://gitlab.gnome.org/GNOME/libgxps/-/blob/f5027ed09c767e8a02e652fbc77dcea79e19e10d/libgxps/gxps-path.c#L832-L848"},{"type":"REPORT","url":"https://hackmd.io/@haind-pwn/libgxps-poly-segment-points-arity-oob-read"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/gnome-libgxps-through-0.3.2-heap-out-of-bounds-read-via-path-geometry-start-element"}],"affected":[{"package":{"name":"libgxps","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libgxps?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.2.3.2-1"],"ecosystem_specific":{"binaries":[{"binary_name":"gir1.2-gxps-0.1","binary_version":"0.2.3.2-1"},{"binary_name":"libgxps-utils","binary_version":"0.2.3.2-1"},{"binary_name":"libgxps2","binary_version":"0.2.3.2-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111132.json"}},{"package":{"name":"libgxps","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libgxps?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.3.0-1","0.3.0-2"],"ecosystem_specific":{"binaries":[{"binary_name":"gir1.2-gxps-0.1","binary_version":"0.3.0-2"},{"binary_name":"libgxps-utils","binary_version":"0.3.0-2"},{"binary_name":"libgxps2","binary_version":"0.3.0-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111132.json"}},{"package":{"name":"libgxps","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libgxps?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.3.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"gir1.2-gxps-0.1","binary_version":"0.3.1-1"},{"binary_version":"0.3.1-1","binary_name":"libgxps-utils"},{"binary_version":"0.3.1-1","binary_name":"libgxps2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111132.json"}},{"package":{"name":"libgxps","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libgxps?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.3.2-1build1","0.3.2-2"],"ecosystem_specific":{"binaries":[{"binary_name":"gir1.2-gxps-0.1","binary_version":"0.3.2-2"},{"binary_version":"0.3.2-2","binary_name":"libgxps-utils"},{"binary_version":"0.3.2-2","binary_name":"libgxps2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111132.json"}},{"package":{"name":"libgxps","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libgxps?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.3.2-3","0.3.2-4build1","0.3.2-4build2","0.3.2-4build3"],"ecosystem_specific":{"binaries":[{"binary_version":"0.3.2-4build3","binary_name":"gir1.2-gxps-0.1"},{"binary_name":"libgxps-utils","binary_version":"0.3.2-4build3"},{"binary_name":"libgxps2t64","binary_version":"0.3.2-4build3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111132.json"}},{"package":{"name":"libgxps","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/libgxps?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.3.2-6"],"ecosystem_specific":{"binaries":[{"binary_name":"gir1.2-gxps-0.1","binary_version":"0.3.2-6"},{"binary_name":"libgxps-utils","binary_version":"0.3.2-6"},{"binary_version":"0.3.2-6","binary_name":"libgxps2t64"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111132.json"}},{"package":{"name":"libgxps","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libgxps?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.3.2-5","0.3.2-6"],"ecosystem_specific":{"binaries":[{"binary_name":"gir1.2-gxps-0.1","binary_version":"0.3.2-6"},{"binary_name":"libgxps-utils","binary_version":"0.3.2-6"},{"binary_name":"libgxps2t64","binary_version":"0.3.2-6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111132.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H"},{"type":"CVSS_V4","sc
