What is CVE-2026-65969?

A vulnerability in the OpenImageIO toolset allows for a denial of service triggered by a truncated TGA file. In susceptible versions prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, processing a malformed GIF frame can result in an out-of-bounds read due to improper handling of palette partition widths during the GIF output process. This can lead to a crash of the application, effectively making the system unavailable. The issue stems from computations involving signed 32-bit arithmetic, leading to an overflow condition with large images. The affected functions, including GifSplitPalette(), can be found in the source path src/gif.imageio/gif.h. Users are recommended to upgrade to the fixed versions to mitigate this vulnerability.

Affected Version(s)

OpenImageIO < 3.0.21.0 < 3.0.21.0
