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

  - Stack-based buffer overflow vulnerability exists in orcparse.c of ORC versions prior to 0.4.39. If a
    developer is tricked to process a specially crafted file with the affected ORC compiler, an arbitrary code
    may be executed on the developer's build environment. This may lead to compromise of developer machines or
    CI build environments. (CVE-2024-40897)

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