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.

CVE-2026-111132 [MEDIUM] CWE-125 libgxps: libgxps: Denial of Service via crafted XPS document
libgxps: libgxps: Denial of Service via crafted XPS document
A flaw was found in libgxps. An attacker can exploit this vulnerability by convincing a user to open a specially crafted XML Paper Specification (XPS) document containing malformed curve segment attributes. Successful exploitation triggers an out-of-bounds memory read, primarily causing an application crash that results in a Denial of Service (DoS), or potentially exposing adjacent memory data.
