When building nested elements using xml.dom.minidom methods such as appendChild() that have a dependency on _clear_id_cache() the algorithm is quadratic. 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()
Отчет
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.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
