February Patch Tuesday 2015 comes after a quite turbulent month for information security professionals. Not so much Microsoft, but Adobe has been keeping us busy with multiple disclosed 0-day vulnerabilities their Flash software. All of the known issues have been very quickly addressed by Adobe (APSB15-02, 03 and 04), typically turning around a fix in less than a week. Still, it is worrisome to see the amount of problems that cyber criminals are able to find in software that we all have installed and use in our daily lives.
Update: Microsoft has modified the bulletin MS14-045 for Windows and excluded the patch for the font handling vulnerability CVE-2014-1819. The patch can cause the system to lockup (BSOD) and present problems with fonts that are not installed in the default location. Microsoft recommends uninstalling KB2982791 at this time. For more information take a look at the KB article itself. We are interested to know how widespread these problems are. Were you affected? Do you install important level patches immediately or do you wait for a cool-off period? These questions are important especially when you consider the availability of 1-day exploits, where attackers reverse engineer patches to find new attack vectors:
This example is taken from the capability description of commercial exploit tool (Gamma’s FinFly) but it illustrates the capabilities that a good attack team has.
Original: It is August Patch Tuesday, the week after Black Hat and DEF CON and we are getting nine bulletins from Microsoft with a total of 41 vulnerabilities addressed plus a new version of Adobe Flash. In addition Microsoft is introducing some new capabilities for automatic ActiveX blocking and announced the phase out of old browsers. All in all, a pretty busy Patch Tuesday with 2 patches that address 0-day vulnerabilities that are seeing attacks in the wild – Internet Explorer and Adobe Flash.
While the Black Hat security conference is ongoing in Las Vegas (stay tuned to this blog for a rundown of our favorite presentations), Microsoft has published their Advance Notice for the month of August. That document gives us an idea of the size of next week’s Patch Tuesday: we will get nine bulletins affecting a wide variety of Microsoft software including Internet Explorer, Windows, Office, SQL Server and Sharepoint. Two of the bulletins are rated “critical,” as they allow for Remote Code Execution (RCE) and a third one for Microsoft Office OneNote also provides RCE capabilities.
