A heap out of bounds read vulnerability exists in the handling of IPTC data while parsing TIFF images in OpenImageIO v2.3.19.0. A specially-crafted TIFF file can cause a read of adjacent heap memory, which can leak sensitive process information. An attacker can provide a malicious file to trigger this vulnerability.
