Description
GNU LibreDWG through 0.14.8612 contains a global out-of-bounds read vulnerability in the AcDs decoder acds_private() that allows attackers to read beyond a static table via an unchecked schema property type index. Attackers can supply a crafted R2004 or R2010+ DWG file with a large 'schdat' property type value to crash dwgread, dwg2dxf, or any application using LibreDWG.
