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
