Description Patrick Del Bello 2022-12-23 12:55:16 UTC

Multiple code execution vulnerabilities exist in the IFFOutput::close() functionality of OpenImageIO Project OpenImageIO v2.4.4.2. A specially crafted ImageOutput Object can lead to a heap buffer overflow. An attacker can provide malicious input to trigger these vulnerabilities.This vulnerability arises when the `ymax` variable is set to 0xFFFF and `m_spec.format` is `TypeDesc::UINT16`
