USN-5446-1 fixed a vulnerability in dpkg. This update provides
the corresponding update for Ubuntu 16.04 ESM.
Original advisory details:
Max Justicz discovered that dpkg incorrectly handled unpacking certain
source packages. If a user or an automated system were tricked into
unpacking a specially crafted source package, a remote attacker could
modify files outside the target unpack directory, leading to a denial of
service or potentially gaining access to the system.
It was discovered that NTFS-3G was incorrectly validating NTFS
metadata in its ntfsck tool by not performing boundary checks. A
local attacker could possibly use this issue to cause a denial of
service or to execute arbitrary code.
The Content Mask WordPress plugin before 1.8.4.1 does not have authorisation and CSRF checks in various AJAX actions, as well as does not validate the option to be updated to ensure it belongs to the plugin. As a result, any authenticated user, such as subscriber could modify arbitrary blog options
The BannerMan WordPress plugin through 0.2.4 does not sanitize or escape its settings, which could allow high-privileged users to perform Cross-Site Scripting attacks when the unfiltered_html is disallowed (such as in multisite)
The IMDB info box WordPress plugin through 2.0 does not sanitize and escape some of its settings, which could allow high-privileged users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed
The User Meta WordPress plugin before 2.4.3 does not sanitise and escape the Form Name, as well as Shared Field Labels before outputting them in the admin dashboard when editing a form, which could allow high privilege users to perform Cross-Site Scripting attacks even when unfiltered_html is disallowed
The JivoChat Live Chat WordPress plugin before 1.3.5.4 does not properly check CSRF tokens on POST requests to the plugins admin page, and does not sanitise some parameters, leading to a stored Cross-Site Scripting vulnerability where an attacker can trick a logged in administrator to inject arbitrary javascript.
