An update for libxml2 is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP2 and openEuler-20.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2022-1582 Final 1.0 1.0 2022-03-19 Initial 2022-03-19 2022-03-19 openEuler SA Tool V1.0 2022-03-19 libxml2 security update An update for libxml2 is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP2 and openEuler-20.03-LTS-SP3. This library allows to manipulate XML files. It includes support to read, modify and write XML and HTML files. There is DTDs support this includes parsing and validation even with complex DtDs, either at parse time or later once the document has been modified. The output can be a simple SAX stream or and in-memory DOM like representations. In this case one can use the built-in XPath and XPointer implementation to select sub nodes or ranges. A flexible Input/Output mechanism is available, with existing HTTP and FTP modules and combined to an URI library.
