Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for libxml2 fixes several issues. Theses security issues
were fixed :

- CVE-2017-16932: Fixed infinite recursion could lead to
an infinite loop or memory exhaustion when expanding a
parameter entity in a DTD (bsc#1069689).

- CVE-2017-15412: Prevent use after free when calling
XPath extension functions that allowed remote attackers

has attempted to automatically clean and format it as much as possible
without introducing additional issues.
