Availability can be impacted when building excessively nested documents.", "A flaw was found in cpython. This vulnerability allows impacted availability via a quadratic algorithm in `xml.dom.minidom` methods, such as `appendChild()`, when building excessively nested documents due to a dependency on `_clear_id_cache()`" ],
  "statement" : "This vulnerability is rated Important for Red Hat products as it can lead to a denial of service. The flaw exists in the `xml.dom.minidom` module of cpython, where a quadratic algorithm in methods like `appendChild()` can be triggered when processing excessively nested XML documents. When successfully exploited this may impact the availability of applications utilizing this functionality across affected Red Hat products.",
