Sources and claim methodology

Upstream source description

Blender before 4.5.15 and 5.x before 5.2.3 contains a heap out-of-bounds read vulnerability in read_file_dna() that reads a GLOB block field without validating its declared length. Attackers can supply a crafted .blend file with a truncated GLOB block that, when opened, triggers the out-of-bounds read and crashes Blender.
