CVE-2022-35099Public exploit

Application crash via out-of-bounds pixel write

Published Sep 23, 2022 · Updated May 22, 2025

A stack-buffer overflow in SWFTools pdf2swf commit 772e55a2 allows local users to crash the converter via a crafted PDF. ImageStream::getPixel writes a decoded image byte past the four-byte pixBuf stack object while pdf2swf renders the file. Processing the file with pdf2swf is required; the demonstrated consequence is an AddressSanitizer-detected abort, with no reported confidentiality or integrity impact.
