CVE-2026-111167 Details
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.
A global out-of-bounds read vulnerability has been identified in GNU LibreDWG versions through 0.14.8612. The issue resides in the AcDs decoder, specifically within the 'acds_private()' function. This vulnerability allows attackers to read beyond a static table by exploiting an unchecked schema property type index. By supplying a crafted R2004 or R2010+ DWG file with a large 'schdat' property type value, attackers can cause applications using LibreDWG, such as 'dwgread' and 'dwg2dxf', to crash.
The vulnerability can be fixed by adding a range check for the property type index before it is used to access the lookup table. This can be done by modifying the AcDs schema data decoder to include a conditional check that ensures the index is within valid bounds, rejecting any out-of-range values.
