CVE-2026-63420

01/תיאור (מקור, אנגלית)

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, An indexed psd with transparency metadata creates fewer stored channel_buffers than the spec.nchannels value advertised by the rawcolor path. when oiio:rawcolor or psd:rawdata is enabled, psdinput::read_native_scanline() passes spec.nchannels to psdinput::interleave_row(), which indexes beyond channel_buffers, resulting in a heap out-of-bounds read and process crash. The affected implementation is identified by src/psd.imageio/psdinput.cpp, PSDInput::read_native_scanline(), PSDInput::interleave_row(), oiio:RawColor, psd:RawData, channel_buffers, and spec.nchannels, 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.
