OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, a signed 32-bit integer overflow in the loop index expression i * 4 inside SwapRGBABytes() causes the function to compute a large negative pointer offset when processing kABGR DPX images with large dimensions. The immediate crash is an out-of-bounds read (the memcpy at line 45 reads from &input[i * 4] first), but the subsequent write operations at lines 46-49 target the same wrapped offset - making this a combined OOB read+write primitive. This vulnerability is fixed in 3.0.18.0 and 3.1.13.0.
AnalysisAI
Remote code execution in OpenImageIO versions before 3.0.18.0 and 3.1.13.0 allows unauthenticated attackers to achieve arbitrary read/write memory access by delivering a maliciously crafted kABGR DPX image file with oversized dimensions. The signed integer overflow in SwapRGBABytes() creates a negative pointer offset that enables both out-of-bounds read via memcpy and subsequent out-of-bounds writes, potentially leading to code execution when a user opens the malicious image. …

RemediationAI
Within 24 hours: Inventory all systems running OpenImageIO 3.0.x or 3.1.x, particularly in VFX, animation, and media production environments; restrict file import from untrusted sources. Within 7 days: Upgrade to OpenImageIO 3.0.18.0 or 3.1.13.0 (or later stable release); validate compatibility with dependent applications before production deployment. …
