CPython 3.9 and earlier doesn't disallow configuring an empty list ("[]") for SSLContext.set_npn_protocols() which is an invalid value for the underlying OpenSSL API. This results in a buffer over-read when NPN is used (see CVE-2024-5535 for OpenSSL). This vulnerability is of low severity due to NPN being not widely used and specifying an empty list likely being uncommon in-practice (typically a protocol name would be configured).

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - CPython 3.9 and earlier doesn't disallow configuring an empty list ([]) for     SSLContext.set_npn_protocols() which is an invalid value for the underlying OpenSSL API. This results in a     buffer over-read when NPN is used (see CVE-2024-5535 for OpenSSL). This vulnerability is of low severity     due to NPN being not widely used and specifying an empty list likely being uncommon in-practice (typically     a protocol name would be configured). (CVE-2024-5642)

Note that Nessus relies on the presence of the package as reported by the vendor.
