Show the technical text from the sources

Blender before 4.5.15 and 5.x before 5.2.3 contains an out-of-bounds read vulnerability in blo_bhead_id_* accessors in readfile.cc that read ID fields without block length checks. Attackers can supply a crafted .blend file with short ID blocks that, when browsed or appended from, causes heap over-reads leading to crashes or heap memory disclosure.
