                     CVE-2026-0891

    Multiple security issues have been found in the Mozilla Firefox web
    browser, which could potentially result in the execution of arbitrary
    code, sandbox escape, information disclosure or spoofing.

    For Debian 11 bullseye, these problems have been fixed in version
    140.7.0esr-1~deb11u1.

    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 LTS security advisories, how to apply
    these updates to your system and frequently asked questions can be
