Synopsis

The remote openSUSE host is missing a security update.

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).

This update was imported from the SUSE:SLE-12-SP2:Update update project.

Solution

Update the affected libxml2 packages.
