    Package        : firefox-esr     Version        : 128.3.0esr-1~deb11u2     CVE ID         : CVE-2024-9392 CVE-2024-9393 CVE-2024-9394 CVE-2024-9401

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

    Debian follows the extended support releases (ESR) of Firefox.
    Starting with this update we're now following the 128.x releases.

    Between 115.x and 128.x, Firefox has seen a number of feature     updates. For more information please refer to     https://www.mozilla.org/en-US/firefox/128.0esr/releasenotes/

    For Debian 11 bullseye, these problems have been fixed in version     128.3.0esr-1~deb11u2.

    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
