Does this matter?
Lower severity and a low EPSS score (3.50%). Track it; it rarely justifies an emergency change on its own.
Description
A vulnerability found in libxml2 in versions before 2.9.11 shows that it did not propagate errors while parsing XML mixed content, causing a NULL dereference. If an untrusted XML document was parsed in recovery mode and post-validated, the flaw could be used to crash the application. The highest threat from this vulnerability is to system availability.
