Adobe, Microsoft Push Reader, Windows Fixes

Adobe and Microsoft each issued updates today to fix critical security problems with their software. Adobe’s patch tackles 17 flaws in its Acrobat and PDF Reader products. Microsoft released nine update bundles to plug at least 22 security holes in Windows and associated software.

brokenwindowsSix of the nine patches Microsoft is pushing out today address flaws the software giant considers “critical,” meaning the vulnerabilities could be exploited by malware or miscreants to break into vulnerable computers remotely without any help from users. The critical updates tackle problems with Internet Explorer, Microsoft Edge, Office and Silverlight, among other components. Links to all of the updates are available here.

As noted by security firm Qualys, several versions of Internet Explorer will get their last security updates this month, including IE 11 on Windows 7 and 10; IE 8, 9 and 10; IE 10 on Server 2012; IE 9 on Vista Service Pack 2 and Server 2008; and IE7 and IE8. If you’re using one of these older versions of IE, consider switching — either to a newer, supported version of IE, or to something less tightly bound to the Windows operating system, such as Google Chrome.

Adobe, Microsoft Push Critical Security Fixes

Adobe and Microsoft on Tuesday each released security updates to remedy critical vulnerabilities in their software. Adobe pushed patches to plug at least 56 security holes present in Adobe Reader and Acrobat, as well as a fix for Flash Player that corrects 13 flaws. Separately, Microsoft issued six update bundles to address at least 33 security problems in various versions of Windows, Microsoft Office and other software.

Three of the patches Microsoft issued earned the company’s most dire “critical” rating, meaning they could be exploited by hackers or malware to take complete control over vulnerable systems without any help from users. According to security firm Shavlik, four of the flaws involve vulnerabilities that were publicly disclosed by someone other than Microsoft prior to this week. The implication here is that malware writers may have had a head start figuring out ways to exploit several of these flaws, so it’s probably best not to let too much grass grow under your feet before applying this month’s updates.

Microsoft, Adobe Push Critical Security Fixes

If you use Microsoft or Adobe software products, chances are that software is now dangerously out of date. Microsoft today released seven update bundles to fix two dozen security vulnerabilities in Windows and supported software. Adobe pushed patches to correct critical flaws in Acrobat, Reader and Flash Player, including a bug in Flash that already is being exploited.

brokenwindowsFour of the seven updates from Microsoft earned a “critical” rating, which means the patches on fix vulnerabilities that can be exploited by malware or attackers to seize control over vulnerable systems without any help from users (save for perhaps visiting a hacked or malicious Web site). One of those critical patches — for Internet Explorer — plugs at least 14 holes in the default Windows browser.

Another critical patch plugs two vulnerabilities in Microsoft Word and Office Web Apps (including Office for Mac 2011). There are actually three patches this month that address Microsoft Office vulnerabilities, including MS14-082 and MS-14-083, both of which are rated “important.” A full breakdown of these and other patches released by Microsoft today is here.

Adobe’s Flash Player update brings the player to v. for Windows and Mac users, and fixes at least six critical bugs in the software. Adobe said an exploit for one of the flaws, CVE-2014-9163, already exists in the wild.

“These updates address vulnerabilities that could potentially allow an attacker to take over the affected system,” the company said in its advisory. Continue reading →

Adobe, Microsoft Push Critical Security Fixes

Adobe and Microsoft today each issued software updates to fix critical security issues in their products. Microsoft released eight patch bundles to address 26 different vulnerabilities in Windows and other software – including not just one but two zero-day bugs in Internet Explorer. Adobe’s patches fix a single critical vulnerability present in both Adobe Acrobat and Reader.

crackedwinFour of the eight patch bulletins from Microsoft earned its most dire “critical” rating, meaning the updates fix problems deemed so severe that miscreants or malware could use them to break into vulnerable systems without any help from users. The patches impact a broad range of Microsoft products, including Windows, IE, SharePoint, .NET Framework, Office and Silverlight.

Front and center in the Microsoft patch batch is MS13-080, which addresses the zero-day IE vulnerability (CVE-2013-3893) that Microsoft first warned about on Sept. 17, as well as nine other security flaws in the default Windows Web browser. Amping up the threat level on this flaw, exploit code allowing attackers to leverage the flaw was released publicly last week as a module for the Metasploit exploit framework, a penetration testing toolkit.

Microsoft late last month released a stopgap “Fix It” solution to block exploits against the zero-day flaw, and the good news is that if you already applied that solution, you don’t need to undo those changes before applying this update. The bad news is that this isn’t the only zero-day vulnerability fixed in the IE patch bundle: Researchers at Trustwave Spiderlabs say they’ve confirmed that attackers are already exploiting one of the other flaws fixed in this IE update  (CVE-2013-3897).
