EulerOS Virtualization for ARM 64 3.0.2.0 : libxml2 (EulerOS-SA-2020-1533)
high Nessus Plugin ID 136236
Synopsis
The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.Description
According to the versions of the libxml2 packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :- 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. Security Fix(es):xmlParseBalancedChunkMemoryRecover in parser.c in libxml2 before 2.9.10 has a memory leak related to newDoc->oldNs.(CVE-2019-19956)xmlStringLenDecodeEntitie s in parser.c in libxml2 2.9.10 has an infinite loop in a certain end-of-file situation.(CVE-2020-7595)A memory leak was found in the xmlSchemaValidateStream function of libxml2. Applications that use this library may be vulnerable to memory not being freed leading to a denial of service. System availability is the highest threat from this vulnerability.(CVE-2019-20388)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
