CVE-2023-43115: 
Ghostscript vulnerability analysis and mitigation

Overview

CVE-2023-43115 affects Artifex Ghostscript through version 10.01.2. The vulnerability exists in the gdevijs.c component of GhostPDL, which can lead to remote code execution through crafted PostScript documents by switching to the IJS device or changing the IjsServer parameter after SAFER has been activated (NVD, Ghostscript).

Technical details

The vulnerability has a CVSS v3.1 base score of 8.8 (High), with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. The issue stems from the IJS device's inherent need to execute commands to start the IJS server, which is a documented risk when the IJS server is specified on a gs command line (NVD).

Impact

The vulnerability allows attackers to achieve remote code execution through specially crafted PostScript documents. This can lead to high impacts on confidentiality, integrity, and availability of the affected systems (NVD).

Mitigation and workarounds

The vulnerability has been fixed in Ghostscript/GhostPDL version 10.02.0. Due to the remote code execution risk, it is strongly recommended to upgrade to version 10.02.0 or later as a matter of urgency (Ghostscript).

Community reactions

Multiple Linux distributions have released security updates to address this vulnerability, including Fedora 38 and 39, which have updated their packages to include the fix (Fedora Mailing List).
