January 2018 Update Summary

Last Tuesday Microsoft released their routine security updates to address 56 vulnerabilities more formally known as CVEs (defined). Further details are provided within Microsoft’s Security Updates Guide.

====================

Separately Adobe released Flash Player v28.0.0.137 to address a single priority 2 CVE.

As always; you can monitor the availability of security updates for most your software from the following websites (among others) or use Secunia PSI:
—————
US Computer Emergency Readiness Team (CERT) (please see the “Information on Security Updates” heading of the “Protecting Your PC” page):

https://www.us-cert.gov/

A further useful source of update related information is the Calendar of Updates. News/announcements of updates in the categories of General SoftwareSecurity Software and Utilities are available on their website. The news/announcements are very timely and (almost always) contain useful direct download links as well as the changes/improvements made by those updates (where possible).

If you like and use it, please also consider supporting that entirely volunteer run website by donating.

====================
For January’s Microsoft updates, I will prioritize the order of installation below. I will discuss this month’s out of band (outside of the regular schedule) patches for Meltdown and Spectre in a separate blog post; the relevant CVEs are still listed below. A useful list of all CVEs for this month is present here:

====================
CVE-2017-5753 – Bounds check bypass (known as Spectre Variant 1)

CVE-2017-5715 – Branch target injection (known as Spectre Variant 2)

CVE-2017-5754 – Rogue data cache load (known as Meltdown Variant 3)

CVE-2018-0802: Microsoft Office zero day (similar to Novembers Office equation editor vulnerability)

Microsoft Office (18 further CVEs)

Microsoft Edge and Internet Explorer (multiple versions of Edge and IE affected)

====================

Please install the remaining updates at your earliest convenience.

As usual; I would recommend backing up the data on any device for which you are installing updates to prevent data loss in the rare event that any update causes unexpected issues.

For this month; please take extra care with your back up to ensure you can restore your systems should you wish to revert your systems prior to installing the Meltdown and Spectre patches should you wish to uninstall the Security only bundle of updates or the updates are causing your system to become unstable.

Thank you.

=======================
Wireshark 2.4.4 and 2.2.12
=======================
v2.4.4: 3 CVEs (defined) resolved

v2.2.12: 4 CVEs resolved

As per standard process Linux distributions can obtain this update using the operating systems standard package manager (if the latest version is not installed automatically using the package manager you can instead compile the source code (v2.4.4) or v2.2.11). This forum thread and this forum thread may also be helpful to you with installing Wireshark on your Linux based system.

For Mac OS X and Windows, the update is available within the downloads section of the Wireshark website. In addition, a detailed FAQ for Wireshark is available here.

====================
Update: 24th January:
====================
Oracle:
====================
Oracle have resolved 237 vulnerabilities with the security updates they have made available this month. Further details and installation steps are available here. Within the 237 vulnerabilities addressed, 21 vulnerabilities were addressed in the Java runtime. 18 of these 21 are remotely exploitable without an attacker needing to obtain a user’s username and password (their credentials).

If you use any of the Oracle products listed here, please install the appropriate security updates as soon as possible.

Particular priority should be given to Oracle WebLogic Server and PeopleSoft due to documented incidents of attackers using such installations for crypto currency mining with one such incident resulting in more than USD $226,000 being mined. Further details are available in the following blog post from security vendor Onapsis.
