Title
LibreCAD libdxfrw through LC2.2.0 Stack Out-of-Bounds Read via dwgReader18::readFileHeader
Summary
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.
Severity

Title
LibreCAD libdxfrw through LC2.2.0 Stack Out-of-Bounds Read via dwgReader18::readFileHeader
Summary
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.
Severity
CWE
- CWE-125 - Out-of-bounds Read
