CVE-2020-22628Public exploitNetwork attack vector

Application crash via crafted CRW processing

Published Aug 22, 2023 · Updated Oct 3, 2024

Out-of-bounds read in LibRaw 0.19.5 and earlier allows attackers to crash an image-processing application via a crafted CRW file. The stretch() routine in src/postprocessing/aspect_ratio.cpp reads beyond an allocated buffer while processing the malformed file. Exploitation requires a target application linked to LibRaw to process the attacker-supplied image, and the demonstrated consequence is an access-violation crash.
