There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Nokogiri is an open source XML and HTML library for the Ruby programming language. Nokogiri `1.13.8` and
    `1.13.9` fail to check the return value from `xmlTextReaderExpand` in the method
    `Nokogiri::XML::Reader#attribute_hash`. This can lead to a null pointer exception when invalid markup is
    being parsed. For applications using `XML::Reader` to parse untrusted inputs, this may potentially be a
    vector for a denial of service attack. Users are advised to upgrade to Nokogiri `>= 1.13.10`. Users may be
    able to search their code for calls to either `XML::Reader#attributes` or `XML::Reader#attribute_hash` to
    determine if they are affected. (CVE-2022-23476)

The remote Fedora 36 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2022-acff3f54b2 advisory.
