The remote Fedora 38 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2023-60cf98b7e6 advisory.

  • GNU Binutils before 2.40 was discovered to contain a memory leak vulnerability var the function find_abstract_instance in dwarf2.c. (CVE-2022-48065)

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