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

critical Nessus Plugin ID 97015

Language:

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.
