                     CVE-2025-8035

    Multiple security issues have been found in the Mozilla Firefox web
    browser, which could potentially result in the execution of arbitrary
    code.

    For the stable distribution (bookworm), these problems have been fixed in
    version 128.13.0esr-1~deb12u1.

    We recommend that you upgrade your firefox-esr packages.

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

    Further information about Debian Security Advisories, how to apply
    these updates to your system and frequently asked questions can be
    found at: https://www.debian.org/security/
