Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5957-1 advisory.

 - 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. (CVE-2018-19105)

 - 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. (CVE-2021-21898)

 - 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. (CVE-2021-21899)

 - 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. (CVE-2021-21900)

 - 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. (CVE-2021-45341)

 - 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. (CVE-2021-45342)

 - 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. (CVE-2021-45343)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected librecad and / or librecad-data packages.
