MetricsAV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Python (affected versions not specified)
Description The xml.parsers.expat and xml.etree.ElementTree modules use insufficient entropy for Expat hash-flooding protection. This allows a specially crafted XML document to trigger hash flooding, a condition where many keys are mapped to the same hash bucket, significantly slowing down processing.
Recommendations Update libexpat to version 2.8.0 or later and apply the available software patch.
