Plus: ‘Dirty COW’ remains unfixed in Google OS
Today is the second Tuesday of the month, and that means a fresh round of security updates from the likes of Microsoft, Adobe and Google.
The November edition of Patch Tuesday brings with it fixes for Windows, Flash Player, Internet Explorer, Edge, Office and Android.
For Microsoft, the monthly update comprises a total of 14 bulletins:
MS16-129 is a cumulative update for the Edge browser addressing 17 CVE-listed flaws, including 12 that could be exploited to perform remote code execution attacks.
MS16-130 is an update for three CVE-listed flaws in Windows that could allow a locally installed application to achieve remote code execution.
MS16-131 patches a flaw in Microsoft Video Control for Windows that allows remote code execution by way of a media file embedded in a webpage or email message.
MS16-132 addresses four CVE-listed vulnerabilities in the Microsoft Graphics Component for Windows, including yet another flaw that allows remote code execution by way of a malformed font file.
MS16-133 is this month’s Office update, addressing a total of 12 CVE-listed vulnerabilities allowing for remote code execution, information disclosure, and denial of service attacks by way of specially crafted files.
The bulletin also includes patches for Office for Mac, so macOS and OS X users are advised to update their software.
MS16-134 is a patch for 10 elevation of privilege vulnerabilities in the Windows Common Log File System Driver.
The vulnerabilities could allow a locally installed application to take complete control over the host machine, if exploited.
MS16-135 patches five elevation of privilege vulnerabilities in the Windows Kernel Mode Driver that potentially allow malicious applications to perform privilege escalation or information disclosure attacks.
MS16-136 is an update for SQL Server that would allow an attacker to elevate their account privileges to view and delete data on the target system or create new accounts.
MS16-137 patches three CVE-listed flaws related to the way Windows handles authentication.
It includes fixes for an elevation of privilege bug, an information disclosure vulnerability, and a denial of service flaw.
MS16-138 is an update for the Microsoft Virtual Hard Disk Driver in Windows and Windows Server.
It addresses four elevation of privilege flaws that, if exploited, would allow an attacker to remotely access other restricted files on a targeted hard drive.
MS16-139 is a fix for a single elevation of privilege flaw in the Windows kernel.
MS16-140 addresses a flaw in the Windows Boot Manager that could allow an attacker with physical access to the system the ability to bypass code integrity checks and run test-signed applications and drivers on the target machine.
MS16-141 is Microsoft’s release of the November security update for Adobe Flash Player, patching all ten remote code execution vulnerabilities.
MS16-142 is the cumulative update for Internet Explorer, addressing seven CVE-listed flaws allowing for remote code execution and information disclosure by way of a malformed webpage.
But wait, there’s more…
Adobe and Google
Not to be outdone, Adobe has posted fixes for nine CVE-listed flaws in Flash Player for Windows, macOS and Linux.
The vulnerabilities could be used by an attacker for remote code execution by way of malformed Flash media files.
For those running Google Chrome, Microsoft Edge, and Internet Explorer version 11 and later, the Flash patches will be automatically downloaded and installed. Users and administrators managing other browsers are advised to patch Flash Player as soon as possible, though killing it is also an option.
Adobe has also released an update to address a flaw in its Connect conferencing application.
That bug, only present on Windows, could allow an attacker to perform a cross-site scripting attack.
Connect for Windows users should update to version 9.5.7.
Google, meanwhile, has released a security update for 82 CVE-listed vulnerabilities in Android.
The Google update, designated 2016-11-05, will be released for all Google devices and is recommended for other Android devices as the “complete” security patch level (vendors also have the option of pushing out a partial patch with only the most serious bug fixes).
Among the flaws addressed in the November Android update are elevation of privilege vulnerabilities in the Nvidia GPU driver firmware, a remote code execution vulnerability in the Qualcomm crypto driver, and denial of service bugs in Bluetooth, OpenJDK and Media Server.
Not fixed was CVE-2016-5195, popularly known as “Dirty COW.” That bug, allowing installed applications to swipe “root” privilege and hijack the device, is slated to be patched in next month’s scheduled update. ®
