CVE-2022-41981Public exploitNetwork attack vector

Code execution via unterminated Targa extension strings

Published Dec 23, 2022 · Updated Apr 14, 2025

A stack buffer overflow in OpenImageIO 2.3.19.0 allows attackers to execute arbitrary code by supplying a crafted Targa file. TGAInput::open reads 41- and 324-byte extension strings into a 324-byte stack union without NUL termination, then uses strlen and sprintf past the buffer. Processing the file is the only reported gate; exploitation can disclose stack data, corrupt process memory, crash the process, or execute code.
