SUSE SLED12 / SLES12 Security Update : libxml2 (SUSE-SU-2017:0380-1)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

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

Description :

This update for libxml2 fixes the following issues :

- CVE-2016-4658: use-after-free error could lead to crash
[bsc#1005544]

- Fix NULL dereference in xpointer.c when in recovery mode
[bsc#1014873]

- CVE-2016-9597: An XML document with many opening tags
could have caused a overflow of the stack not detected
by the recursion limits, allowing for DoS (bsc#1017497).
For CVE-2016-9318 we decided not to ship a fix since it
can break existing setups. Please take appropriate
actions if you parse untrusted XML files and use the new
-noxxe flag if possible (bnc#1010675, bnc#1013930).

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.
