The PSD image loader in Scribus uses unchecked values from PSD file headers as array indexes without bounds validation, leading to a heap out-of-bounds write. The vulnerability exists in the scimgdataloader_psd component and is triggered when processing channel count data. An attacker must convince a user to import a maliciously crafted PSD file; no special privileges or pre-existing access is required.
