EulerOS Virtualization 2.5.0 : libxml2 (EulerOS-SA-2018-1336)

critical Nessus Plugin ID 118424

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

According to the version of the libxml2 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

- A flaw in libxml2 allows remote XML entity inclusion with default parser flags (i.e., when the caller did not request entity substitution, DTD validation, external DTD subset loading, or default DTD attributes). Depending on the context, this may expose a higher-risk attack surface in libxml2 not usually reachable with default parser flags, and expose content from local files, HTTP, or FTP servers (which might be otherwise unreachable).(CVE-2017-7375)

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.

Solution

Update the affected libxml2 package.
