CVE-2025-47814Public exploit

Heap overwrite via unbounded ZIP member read

Published May 10, 2025 · Updated May 13, 2025

Heap-based buffer overflow in GNU PSPP 2.0.1 and earlier allows local users to crash pspp-output via a crafted SPV file. During XML-member extraction, inflate_read passes a crafted read length to fread without bounding it to the heap buffer allocated by inflate_init. Local invocation of pspp-output is required, and the demonstrated out-of-bounds write affects process integrity and availability.
