SUSE SLES11 Security Update : libxml2 (SUSE-SU-2017:0164-1)

high Nessus Plugin ID 96566

Language:

Synopsis

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

Description

This update for libxml2 fixes the following issues :

- CVE-2016-9318: libxml2 did not offer a flag directly indicating that the current document may be read but other files may not be opened, which made it easier for remote attackers to conduct XML External Entity (XXE) attacks via a crafted document (bsc#1010675).

- Prevent NULL dereference in xpointer.c and xmlDumpElementContent, and infinite recursion in xmlParseConditionalSections when in recovery mode(bnc#1014873)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
