LibreCAD through 2.2.1.6 Heap Out-of-Bounds Write via dwgReader18::parseDataPage

LibreCAD through 2.2.1.6 contains a heap-based out-of-bounds write vulnerability in the bundled libdxfrw dwgReader18::parseDataPage() function due to unchecked buffer size and page offsets. Attackers can craft an AC1018 (R2004) DWG file with malicious startOffset values that cause decompress18 to write past the heap buffer when opened, causing crashes and potential code execution.

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

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.

A Buffer Overflow vulnerability in importshp plugin in LibreCAD 2.2.0 allows attackers to obtain sensitive information via a crafted DBF file.

In LibreCAD 2.2.0, a NULL pointer dereference in the HATCH handling of libdxfrw allows an attacker to crash the application using a crafted DXF document.

A buffer overflow vulnerability in CDataList of the jwwlib component of LibreCAD 2.2.0-rc3 and older allows an attacker to achieve Remote Code Execution using a crafted JWW document.

A buffer overflow vulnerability in CDataMoji of the jwwlib component of LibreCAD 2.2.0-rc3 and older allows an attacker to achieve Remote Code Execution using a crafted JWW document.

A code execution vulnerability exists in the dxfRW::processLType() functionality of LibreCad libdxfrw 2.2.0-rc2-19-ge02f3580. A specially-crafted .dxf file can lead to a use-after-free vulnerability. An attacker can provide a malicious file to trigger this vulnerability.

A code execution vulnerability exists in the dwgCompressor::copyCompBytes21 functionality of LibreCad libdxfrw 2.2.0-rc2-19-ge02f3580. A specially-crafted .dwg file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.

A code execution vulnerability exists in the dwgCompressor::decompress18() functionality of LibreCad libdxfrw 2.2.0-rc2-19-ge02f3580. A specially-crafted .dwg file can lead to an out-of-bounds write. An attacker can provide a malicious file to trigger this vulnerability.

LibreCAD 2.1.3 allows remote attackers to cause a denial of service (0x89C04589 write access violation and application crash) or possibly have unspecified other impact via a crafted file.
