CVE-2022-35080Public exploit

Application crash via out-of-bounds PNG reads

Published Oct 13, 2022 · Updated May 15, 2025

Heap-buffer over-read in SWFTools commit 772e55a2 allows local users to crash png2swf by supplying a crafted PNG file. The png_load routine in lib/png.c reads one or four bytes past heap allocations while decoding malformed image data. Exploitation requires a user to invoke png2swf on the file; the demonstrated consequence is process termination without confidentiality or integrity impact.
