    Package        : pdfminer
    Version        : 20200726-1+deb11u1
    CVE ID         : CVE-2025-64512
    Debian Bug     : 1120642

    It was discovered that there was a potential arbitrary code execution
    in pdfminer, a tool for extracting information from PDF documents. A
    malicious, zipped pickle file could have contained code that might
    have been executed when the PDF was processed.

    For Debian 11 bullseye, this problem has been fixed in version
    20200726-1+deb11u1.

    We recommend that you upgrade your pdfminer packages.

    For the detailed security status of pdfminer please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/pdfminer
