Spatialite CVEs and Security Vulnerabilities

CVE-2026-112048

libspatialite through 5.1.0 Uncontrolled Memory Allocation via ParseWkbPolygon Ring Count

libspatialite through 5.1.0 fails to validate the polygon ring count in ParseWkbPolygon, allowing attackers to trigger uncontrolled interior-ring allocation via crafted geometry BLOBs. Attackers can supply a crafted polygon in a SpatiaLite database or ST_GeomFromWKB input to crash the process or corrupt heap memory on 32-bit builds.

CVE-2026-112052

libspatialite through 5.1.0 Integer Overflow in WKB Geometry Parsing

libspatialite through 5.1.0 contains an integer overflow vulnerability in the WKB point and vertex count size guard of ParseWkbLine and related parsers in gg_wkb.c, allowing out-of-bounds reads. Attackers can supply a crafted geometry BLOB with a large point count, for example in a SpatiaLite database file, to crash the process or corrupt heap memory on 32-bit builds.
