    Package        : org-mode
    CVE ID         : CVE-2024-39331
    Debian Bug     : 1074136

    It was discovered that Org Mode for Emacs is prone to arbitrary shell
    code evaluation when opening a specially crafted Org file.

    This update includes updates pending for the upcoming point releases
    including other security fixes.

    For the oldstable distribution (bullseye), this problem has been fixed
    in version 9.4.0+dfsg-1+deb11u3.

    We recommend that you upgrade your org-mode packages.

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

    Further information about Debian Security Advisories, how to apply
    these updates to your system and frequently asked questions can be
