LibreCAD libdxfrw through LC2.2.0 (LibreCAD through 2.2.1.5) contains a stack-based out-of-bounds read vulnerability in dwgReader18::readFileHeader() caused by calling strlen on non-NUL-terminated buffers. Attackers can supply a crafted AC1018, AC1024 or AC1027 DWG file without NUL bytes in the decrypted header to read adjacent stack memory and crash the process.
