Name of the Vulnerable Software and Affected Versions libxml2 (affected versions not specified)
Description The RelaxNG parser in libxml2 does not limit the depth of external schema inclusions when resolving nested <include> directives. This can lead to excessive recursion during parsing with specially crafted or complex schemas, potentially causing stack exhaustion and application crashes, resulting in a denial-of-service condition.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
