OpenImageIO: PSD RawColor invalid color mode causes global out-of-bounds read and allocation DoS

Assigner: GitHub_M
Reserved: 17.07.2026 Published: 18.09.2026 Updated: 18.09.2026

OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, A crafted psd with an invalid color_mode bypasses normal validation when oiio:rawcolor or psd:rawdata is enabled. psdinput::setup() then uses the attacker-controlled value to index fixed color-mode tables, causing a global out-of-bounds read and potentially a bogus allocation, resulting in denial of service. The affected implementation is identified by src/psd.imageio/psdinput.cpp, PSDInput::validate_header(), PSDInput::setup(), oiio:RawColor, psd:RawData, color_mode, and mode_channel_count, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1.
