    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.
