CVE-2022-35009Public exploitNetwork attack vector

Crash via unchecked decoded-image buffer allocation

Published Aug 16, 2022 · Updated Aug 3, 2024

Resource exhaustion in PNGDec 1.0.0 and 1.0.1 allows attackers to crash the Linux decoding utility with a crafted PNG file. The png_demo path passes PNG::getBufferSize(), a signed product of parsed image height and row pitch, directly to malloc without overflow or upper-bound checks, producing an enormous allocation request. Opening the crafted file is required; the demonstrated result is an AddressSanitizer abort before image decoding, with no reported confidentiality or integrity impact.
