CVE-2026-63420
Description
A flaw was found in OpenImageIO. When processing an indexed Photoshop Document (PSD) image containing transparency metadata with oiio:rawcolor or psd:rawdata enabled, the interleave_row function attempts to read data beyond the bounds of allocated memory. This heap out-of-bounds read can lead to a process crash, resulting in a Denial of Service (DoS).
Statement
Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery. For more information about this vulnerability and the products it affects, please see the linked references.
Mitigation
Avoid processing untrusted or specially crafted PSD image files with applications that use OpenImageIO, especially when `oiio:rawcolor` or `psd:rawdata` features are enabled. This can prevent the application from crashing due to the out-of-bounds read vulnerability.
