The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, 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)
regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls. (CVE-2020-12723)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
