iTextPDF in iText 7 and up to (excluding 4.4.13.3) 7.1.17 allows command injection via a CompareTool filename that is mishandled on the gs (aka Ghostscript) command line in GhostscriptHelper.java.

The versions of Primavera Unifier installed on the remote host are affected by multiple vulnerabilities as referenced in the January 2026 CPU advisory.

  - Vulnerability in the Primavera Unifier product of Oracle Construction and Engineering (component:
    Integration (Apache Tika)). Supported versions that are affected are 21.12.0-21.12.17, 22.12.0-22.12.15,     23.12.0-23.12.16, 24.12.0-24.12.12 and 25.12.0. Easily exploitable vulnerability allows unauthenticated     attacker with network access via HTTP to compromise Primavera Unifier. While the vulnerability is in     Primavera Unifier, attacks may significantly impact additional products (scope change). Successful attacks     of this vulnerability can result in unauthorized update, insert or delete access to some of Primavera     Unifier accessible data as well as unauthorized read access to a subset of Primavera Unifier accessible     data and unauthorized ability to cause a partial denial of service (partial DOS) of Primavera Unifier.
    (CVE-2025-66516)

  - Vulnerability in the Primavera Unifier product of Oracle Construction and Engineering (component: Reports     (iTextPDF)). Supported versions that are affected are 21.12.0-21.12.17, 22.12.0-22.12.15,     23.12.0-23.12.16, 24.12.0-24.12.12 and 25.12.0. Easily exploitable vulnerability allows unauthenticated     attacker with network access via HTTPS to compromise Primavera Unifier. Successful attacks of this     vulnerability can result in takeover of Primavera Unifier. (CVE-2021-43113)

  - Vulnerability in the Primavera Unifier product of Oracle Construction and Engineering (component:
    Integration (Spring Framework)). Supported versions that are affected are 22.12.0-22.12.15,     23.12.0-23.12.16, 24.12.0-24.12.12 and 25.12.0. Easily exploitable vulnerability allows unauthenticated     attacker with network access via HTTP to compromise Primavera Unifier. Successful attacks of this     vulnerability can result in unauthorized access to critical data or complete access to all Primavera     Unifier accessible data. (CVE-2025-41242, CVE-2025-41249)

    Package        : libitext5-java     Version        : 5.5.13-1+deb10u1     CVE ID         : CVE-2021-43113     Debian Bug     : 1014597

    It was discovered that the CompareTool of iText, a Java PDF library which     uses the external ghostscript software to compare PDFs at a pixel level,     allowed command injection when parsing a specially crafted filename.

    For Debian 10 buster, this problem has been fixed in version     5.5.13-1+deb10u1.

    We recommend that you upgrade your libitext5-java packages.
