EulerOS 2.0 SP3 : libxml2 (EulerOS-SA-2018-1156)

High Nessus Plugin ID 110732

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the libxml2 packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

- Use-after-free vulnerability in libxml2 through 2.9.4,
as used in Google Chrome before 52.0.2743.82, allows
remote attackers to cause a denial of service or
possibly have unspecified other impact via vectors
related to the XPointer range-to
function.(CVE-2016-5131)

- parser.c in libxml2 before 2.9.5 mishandles
parameter-entity references because the NEXTL macro
calls the xmlParserHandlePEReference function in the
case of a '%' character in a DTD name.(CVE-2017-16931)

- parser.c in libxml2 before 2.9.5 does not prevent
infinite recursion in parameter
entities.)CVE-2017-16932)

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 packages.
