    Package        : ceph
    Version        : 14.2.21-1+deb11u3
    CVE ID         : CVE-2024-31884
    Debian Bug     : 1126573

    It was discovered that there was an issue in Ceph, the distributed
    storage and file system, where the Python bindings did not correctly
    implement SSL certificate checking.

    For Debian 11 bullseye, this problem has been fixed in version
    14.2.21-1+deb11u3.

    We recommend that you upgrade your ceph packages.

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

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

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
