Description Preview

CVE-2021-42702 affects Inkscape version 0.91, which contains a vulnerability where the application can access an uninitialized pointer. This security flaw could potentially be exploited by an attacker to gain access to unauthorized information. The vulnerability exists in the core functionality of Inkscape 0.91 and may lead to information disclosure, potentially compromising sensitive data processed by the application.

Overview

Inkscape is a free and open-source vector graphics editor used for creating and editing SVG files. Version 0.91 contains a significant security vulnerability where the application accesses an uninitialized pointer. When a pointer is used before it has been properly initialized, it may point to arbitrary memory locations, potentially containing sensitive information. An attacker who can exploit this vulnerability could gain access to data they should not have permission to view. This vulnerability is particularly concerning in industrial control system (ICS) environments where Inkscape might be used with SCADA animation graphic editor extensions.

Remediation

Users and administrators should take the following steps to mitigate this vulnerability:

  1. Update Inkscape to a version newer than 0.91. Current versions have addressed this vulnerability.
  2. If updating is not immediately possible, limit the use of Inkscape 0.91 for processing untrusted SVG files.
  3. Implement network segmentation and restrict access to systems running vulnerable versions of Inkscape.
  4. Monitor systems for unusual activity that might indicate exploitation attempts.
  5. Consider implementing the principle of least privilege for users who need to use Inkscape.
  6. If using Inkscape with SCADA systems or industrial control environments, ensure proper isolation of these systems from untrusted networks.
