Malta: Third Party Patch Roundup – July 2016

Last Updated: 2 August 2016

Authored by Debra Littlejohn Shinder

As we wrap up this month and head into August, summer is more than halfway gone. It's been a long, hot one here in Texas and in many other areas of the U.S. and the world, so we're all looking forward to a little relief in the not-too-distant future.

In the IT world, we would also appreciate some relief from the never-ending flood of new vulnerabilities and exploits and the need to apply patches to fix the issues. Unfortunately, hunting for new ways to get into networks and steal data or take down systems is not a seasonal activity; the bad guys are always hard at work trying to circumvent security mechanisms that are built into our software. That means there's no rest for the weary IT pro.

Now let's take a look at the details of some of this month's patches from major third party security vendors. The following applies as of the date of this writing, which is June 28.

Apple

Apple seems to be on a light/heavy schedule. After a large number of patches in May, they released only one in June. That means we were expecting another deluge this month, and we got it: seven patches spanning their desktop, mobile, watch and TV operating systems as well as the iCloud, iTunes and Safari products.

All of the following were released on July 18:

  • OS X El Capitan v10.11.6 and Security Update 2016-004 – addresses more than 60 different vulnerabilities in various operating system components, including the OS kernel, graphics drivers and components, audio components, FaceTime, QuickTime, Apache, OpenSSL, and more. The most serious of these can be exploited to accomplish remote code execution.
  • iOS 9.3.3 – addresses more than 40 different vulnerabilities in various operating system components, including the Kernel, as well as in Calendar, CoreGraphics, FaceTime, Safari, Siri Contacts, Sandbox Profiles, WebKit and more. The most serious of these can be exploited to accomplish remote code execution.
  • watchOS 2.2.2 – addresses more than 20 vulnerabilities in various operating system components, including the OS kernel, graphics components, Sandbox Profiles and more. Impacts include information disclosure, remote denial of service attack, and the most serious can be exploited to accomplish remote code execution.
  • tvOS 9.2.2 – addresses more than 30 vulnerabilities in various operating system components, including the OS kernel, graphics components, Sandbox Profiles and more. These include denial of service, information leak, and the most serious of these can be exploited to accomplish remote code execution.
  • Safari 9.1.2 – addresses 12 vulnerabilities in the Safari web browser, most of them in the WebKit component. The most serious of these can be exploited to accomplish remote code execution.
  • iTunes 12.4.2 for Windows – addresses 15 vulnerabilities in the iTunes for Windows application software, most of them being memory corruption issues. The update is available for Windows 7 and later.
  • iCloud for Windows 5.2.1 – addresses 15 vulnerabilities in the iCloud for Windows software, most of them being memory corruption issues. The update is available for Windows 7 and later.

For more information about this and the previously issued patches and the vulnerabilities that they address, see the Apple Support web site at https://support.apple.com/en-us/HT201222

Adobe

Adobe had an average month, with the issuance of three security updates that address vulnerabilities in their most popular software (Acrobat/Reader and Flash Player) as well as one of their developer tools.

  • On July 7, Adobe released APSB16-26, which contains security updates for Adobe Acrobat and Reader running on Windows and Mac, to address thirty vulnerabilities. It is rated critical and given a priority rating of 2 on both platforms.

Both of the following were released on their regular Patch Tuesday release schedule, on July 12:

  • APSB16-25 addresses 52 vulnerabilities in Adobe Flash Player running on Windows, Mac, Linux and ChromeOS. It is rated critical and has a priority rating of 1 on all except Adobe Flash Player for Linux, which is assigned a priority rating of 3.
  • APSB16-24 addresses a single vulnerability in Adobe XMP Toolkit for Java, which can lead to information disclosure. It is rated important and has a priority rating of 3.

For more information about these vulnerabilities and updates, see Adobe's Security Bulletins and Advisories web site at https://helpx.adobe.com/security.html or see the individual bulletins linked in each bullet point above.

Google

In July, Google issued multiple security updates for Android that address a total of 108 vulnerabilities. These were released in two "patch level strings," one on July 1 and one on July 5. Two of the issues in the July 1 string are rated critical and there are seven critical issues in the July 5 string. The critical issues include remote code execution vulnerabilities and elevation of privilege vulnerabilities.

For more information, see the Android Security Bulletin – July 2016 at https://source.android.com/security/bulletin/2016-07-01.html

On July 21, Google released Chrome v. 52.0.2743.82 to address multiple vulnerabilities for Windows, Mac and Linux. Exploitation of some of these vulnerabilities may allow a remote attacker to take control of an affected system.

For more information, see the Google Chrome Releases blog at http://googlechromereleases.blogspot.com

Oracle

Oracle normally releases security updates on a quarterly cycle, in January, April, July and October. On July 15, they issued a Critical Patch Update that addresses 276 new vulnerability fixes across all of their product families, including Oracle Java SE as well as many enterprise products. For more information, see the Oracle Critical Patch Update Advisory – July 2016 at

Mozilla

As of this writing (July 28, 2016), Mozilla has not released a new version of Firefox since v. 47, which was released in June and included 13 security fixes.

For more information about those vulnerabilities and fixes, and to check for new version releases, see Mozilla's web site at https://www.mozilla.org/en-US/security/known-vulnerabilities/firefox/

Linux

Popular Linux distros, as usual, have seen a number of security advisories and updates this month. As of the date of this writing (June 28) Ubuntu has issued 24 security notices, which is a relatively low number in comparison to most recent months. Many of these address multiple vulnerabilities and in some cases there are multiple advisories for the same vulnerabilities. Other commercial Linux vendors issued a similar number of updates.

USN-3043-1: OpenJDK 8 vulnerabilities – July 27

Multiple vulnerabilities were discovered in the OpenJDK JRE related to information disclosure, data integrity, and availability. An attacker could exploit these to cause a denial of service, expose sensitive data over the network, or possibly execute arbitrary code.

Information Collection and Use

We require site users to register with Mondaq (and its affiliate sites) to view the free information on the site. We also collect information from our users at several different points on the websites: this is so that we can customise the sites according to individual usage, provide 'session-aware' functionality, and ensure that content is acquired and developed appropriately. This gives us an overall picture of our user profiles, which in turn shows to our Editorial Contributors the type of person they are reaching by posting articles on Mondaq (and its affiliate sites) – meaning more free content for registered users.

We are only able to provide the material on the Mondaq (and its affiliate sites) site free to site visitors because we can pass on information about the pages that users are viewing and the personal information users provide to us (e.g. email addresses) to reputable contributing firms such as law firms who author those pages. We do not sell or rent information to anyone else other than the authors of those pages, who may change from time to time. Should you wish us not to disclose your details to any of these parties, please tick the box above or tick the box marked "Opt out of Registration Information Disclosure" on the Your Profile page. We and our author organisations may only contact you via email or other means if you allow us to do so. Users can opt out of contact when they register on the site, or send an email to unsubscribe@mondaq.com with “no disclosure” in the subject heading
