CVE-2022-35011Public exploitNetwork attack vector

Memory corruption via out-of-bounds DEFLATE write

Published Aug 16, 2022 · Updated Aug 3, 2024

Global buffer overflow in PNGDec commit 8abf6be allows context-dependent attackers to corrupt memory through a crafted PNG file. The inflate_fast decompression path performs a one-byte write immediately beyond the global png object at src/inffast.c line 275. Opening and decoding a crafted PNG is required; the published sample crashes an AddressSanitizer-instrumented Linux png_demo build, and no code execution was demonstrated.
