Scribus before 1.6.7 and 1.7.x before 1.7.4 Out-of-Bounds Read via PICT Planar Image Data
Description

Scribus before 1.6.7 and 1.7.x before 1.7.4 contains an out-of-bounds read vulnerability in the Mac PICT image loader and import plugin when decoding planar pixel data. Attackers can supply a crafted PICT file with manipulated dimensions that, when placed or imported, causes heap over-reads leading to crashes or heap memory disclosure.
