Kerberos 5 (aka krb5) 1.21.2 contains a memory leak vulnerability in /krb5/src/kdc/ndr.c.

An update of the krb5 package has been released.

The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-df2c70dba9 advisory.

    This update fixes multiple CVEs and rebases to the latest upstream version:
    ```

    - New upstream version (1.21.3)

    - Fix double free in klist's show_ccache()       Resolves: rhbz#2257301

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

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
