Echo: libxml2-2.9.1: security update to 2.9.1+e1

critical Tenable Self-Hosted Container Security Plugin ID 476493

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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)

Solution

Update the libxml2-2.9.1 library and its related packages to version 2.9.1+e1 or later.
