"The remote NewStart CGSL host, running version MAIN 6.02, has perl packages installed that are affected by multiple
vulnerabilities:

  - Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular
    expression quantifiers have an integer overflow. (CVE-2020-10543)

  - Perl before 5.30.3 has an integer overflow related to mishandling of a PL_regkind[OP(n)] == NOTHING
    situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction
    injection. (CVE-2020-10878)

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