    Package        : pdfminer
    CVE ID         : CVE-2025-64512
    Debian Bug     : 1120642

    A vulnerability was discovered in pdfminer, a tool for extracting
    information from PDF documents, which may result in the execution of
    arbitrary code if a specially crafted PDF file is processed.

    For the oldstable distribution (bookworm), this problem has been fixed
    in version 20221105+dfsg-1.1~deb12u1.

    For the stable distribution (trixie), this problem has been fixed in
    version 20221105+dfsg-1.1~deb13u1.

    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
