Chrome 68.0.3440.75: security fixes, address bar changes

Leave a comment

The latest version of Chrome includes fixes for forty-two security vulnerabilities. It’s also the first version that will display Not Secure in the address bar for all non-encrypted web pages. When that indicator appears, traffic to and from the viewed page is not being encrypted.

Viewing a non-encrypted web page is not particularly risky, as long as no private information is being transmitted. That means user names, passwords, email addresses, credit card numbers, and so on. However, as discussed here previously, unencrypted sites open up a world of possibilities for intercepting and modifying web traffic.

The release announcement for Chrome 68.0.3440.75 provides additional details regarding the security issues addressed.

The simplest way to update Chrome is also the best way to determine which version you’re running: click the three-vertical-dots icon at the top right, then select Help > About Google Chrome. If your browser isn’t already up to date, this will usually trigger an update.

Java 8 Update 181

Leave a comment

Oracle’s latest Critical Patch Update (CPU) Advisory — for July 2018 — as usual includes a section about Java.

A new version of Java (8 Update 181) addresses eight security vulnerabilities in earlier versions. The Release Highlights page for Java 8 provides additional details on changes in Update 181, most of which are likely only of interest to developers.

If you use Java, and in particular if you use a web browser that has Java enabled, you should install Java 8 Update 181 as soon as possible. Note that the only modern browser that still runs Java applications is Internet Explorer. The easiest way to update Java is to run the Java applet in the Windows Control Panel: on the Update tab, click the Update Now button.

Patch Tuesday for July 2018

Leave a comment

Adobe and Microsoft have issued their monthly updates for July, so even if you’d rather be doing anything else, you should be patching your computers.

We’ll start with Microsoft. As usual, this month’s Security Update Release bulletin serves as little more than a link to the Security Update Guide (SUG), Microsoft’s labyrinthine replacement for the individual bulletins we used to get.

In my experience, the SUG is much easier to digest in the form of a spreadsheet, so the first thing I do there is click the small Download link at the right edge of the page, to the right of the Security Updates heading. If you have Excel — or something compatible — installed, you should be able to open it directly.

Once the spreadsheet is loaded, I recommend enabling the Filter option. In Excel 2007, that setting is in the Sort & Filter section of the Data ribbon (toolbar). This makes every column heading a drop-down list, which allow you to select a particular product or platform, and hide everything else.

Analysis of this month’s updates from the SUG spreadsheet shows that there are sixty-two distinct updates, addressing fifty-three security vulnerabilities in Flash, Internet Explorer, SharePoint, Visual Studio, Edge, Office applications, .NET, and all supported versions of Windows. Seventeen of the updates are flagged as Critical.

As for Adobe, there are updates for Flash (version 30.0.0.134) and Acrobat Reader DC (version 2018.011.20055). The Flash update fixes two vulnerabilities, one of which is Critical. The Acrobat Reader DC update includes fixes for over one hundred security bugs.

Firefox, Mozilla, Patches and updates, Security

Firefox 61.0 – security and performance improvements

Leave a comment

The latest Firefox release features faster page load times and tab switching, improvements to search provider setup, an improved dark theme, better bookmark syncing, and at least eighteen security fixes.

Settings related to the home page and ‘new tab’ page are now in their own section on Firefox’s Options pages. You can access the new section directly using this URL: about:preferences#home.

The Firefox 61.0 release notes provide additional details.

On most computers, Firefox will update itself. You can encourage it by visiting the About page: click the hamburger button, then select Help > About Firefox.

Patch Tuesday for June 2018

Leave a comment

The June 2018 Security Update Release bulletin on Microsoft’s TechNet blog is almost devoid of useful information, but if you click the link to the Security Update Guide, then click the big Go To Security Update Guide button, you’ll see a link to the release notes for this month’s updates.

According to the release notes, this month’s updates affect Internet Explorer, Edge, Windows, Office, Office Services and Web Apps, Flash embedded in IE and Edge, and ChakraCore. Analysis of the information in the SUG reveals that there are forty updates, fixing fifty-one separate vulnerabilities. Eleven of the vulnerabilties are flagged as Critical.

Firefox, Mozilla, Patches and updates, Security

Firefox 60.0.2

Leave a comment

When first published on June 6, the release notes for Firefox 60.0.2 didn’t mention anything about security, but they’ve since been updated to include a reference to a single vulnerability that is fixed in the new version.

The vulnerability fixed in Firefox 60.0.2 is flagged as having both Critical and High impact by Mozilla, and since there are as yet no details in the official vulnerability database for CVE-2018-6126, it’s difficult to know which is correct.

Regardless, if you use Firefox, you should update it as soon as possible. Depending on how it’s configured, Firefox will usually at least let you know that a new version is available within a few hours after it’s published. If not, you can usually trigger an update by clicking the ‘hamburger’ menu icon at the top right, then selecting Help > About.

Chrome 67.0.3396.79 fixes a single security bug

Leave a comment

The latest version of Chrome includes a fix for a single security vulnerability with High severity.

The change log for Chrome 67.0.3396.79 includes a few dozen changes, but none that Google considered worth highlighting in the release announcement, aside from the single vulnerability.

To check your Chrome version, click the vertical-ellipses icon at the top right of its window, then select Help > About Google Chrome. If an update is available, it will usually start downloading automatically.

Flash 30.0.0.113 fixes actively-exploited vulnerability

Leave a comment

Adobe logoOn June 7, Adobe released a new version of Flash, which addresses four vulnerabilities in earlier versions. One of those vulnerabilities is being exploited right now, mostly by way of Office documents attached to email.

The security bulletin for Flash 30.0.0.113 provides additional details.

If you’re using Flash, and in particular if you use a web browser in which Flash is enabled, you should update Flash as soon as possible. On Windows systems, you can do that by going to the Windows Control Panel, then clicking the Flash component. In the Flash Player Settings Manager, go to the Updates tab and click Check Now. That will take you to the official About Flash page, where you can check whether Flash is currently installed, see which version is installed, and download the latest version. Depending on your browser configuration, you may have to click the small gray rectangle to the right of the introductory text, then confirm that you want to allow Flash content to play.

As usual, browsers with embedded Flash (Edge, Chrome, Internet Explorer) will get the new version via their own update mechanisms.

Chrome 67.0.3396.62: security fixes

Leave a comment

Yesterday’s release of Google Chrome brings its current version number to 67.0.3396.62. The new version is mostly about security fixes: there are thirty-four in all, none of which are flagged with Critical severity.

The change log for Chrome 67.0.3396.62 is a monster, listing 10855 changes in all. Don’t try viewing that page with an older computer or browser.

Google hasn’t seen fit to highlight any of the changes in Chrome 67.0.3396.62 in the release announcement, other than mentioning that Site Isolation may or may not be enabled. Site Isolation is a new security feature that’s being rolled out in stages.

As usual, the new Chrome version “will roll out over the coming days/weeks.” If that’s too vague for you (it is for me), an update can usually be triggered by navigating Chrome’s menu (the vertical ellipses icon at the top right) to Help > About Google Chrome.
