"The remote NewStart CGSL host, running version MAIN 7.02, has perl packages installed that are affected by a
vulnerability:

  - A heap buffer overflow vulnerability was discovered in Perl. Release branches 5.34, 5.36, 5.38 and 5.40
    are affected, including development versions from 5.33.1 through 5.41.10. When there are non-ASCII bytes
    in the left-hand-side of the `tr` operator, `S_do_trans_invmap` can overflow the destination pointer `d`.
    $ perl -e '$_ = \x{FF} x 1000000; tr/\xFF/\x{100}/;' Segmentation fault (core dumped) It is believed
    that this vulnerability can enable Denial of Service and possibly Code Execution attacks on platforms that
    lack sufficient defenses. (CVE-2024-56406)

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