Adobe, Microsoft Patch Flash, Windows

Patch Tuesday is again upon us: Adobe today issued updates for Flash Player and AIR, fixing the same critical vulnerability in both products. Microsoft‘s patch bundle of five updates addresses 23 vulnerabilities in Windows, Internet Explorer, and Office, including one bug that is already being actively exploited.

crackedwinA majority of the vulnerabilities fixed in Microsoft’s June patch batch — 19 of them — are addressed in a cumulative update for Internet Explorer (MS13-047). The other fix that Microsoft called specific attention to is MS13-051, which tackles a flaw in Office that “could allow remote code execution if a user opens a specially crafted Office document..or previews or opens a specially crafted email message in Outlook while using Microsoft Word as the email reader.”

This Office flaw, which is present in the latest versions of Office 2003 and Microsoft Office for Mac 2011, is already being exploited in targeted attacks, Microsoft said. According to the company’s advisory, this vulnerability was reported by Google. These attacks fit the profile of previous zer0-day incidents, which use targeted email lures and previously unknown vulnerabilities to break into high-value targets.

“When Google encounters flaws that exploit users’ computers, even when the flaws are in other companies’ software, we take strong action to mitigate those attacks,” a Google spokesperson said in response to a request for comment. “Based on the exploit and the way it has been utilized by attackers, we strongly believe the attacks to be associated with a nation-state organization.”

Adobe’s Flash and AIR updates also fix a critical bug that was reported by Google’s security team, although Adobe says it is not aware of any exploits or attacks in the wild against the vulnerability address in its update. The latest Flash version is 11.7.700.224 for Windows and 11.7.700.225 for Mac OS X.  This link will tell you which version of Flash your browser has installed. IE10 and Chrome should auto-update their versions of Flash. If your version of Chrome is not yet updated to v. 11.7.700.225, you may just need to restart the browser.

Critical Updates for Flash Player, Microsoft Windows

Adobe and Microsoft have each released security updates to fix critical security flaws in their software. Microsoft issued seven update bundles to fix at least 10 vulnerabilities in Windows and other software. Separately, Adobe pushed out a fix for its Flash Player and AIR software that address at least three critical vulnerabilities in these programs.

A majority of the bugs quashed in Microsoft’s patch batch are critical security holes, meaning that malware or miscreants could exploit them to seize control over vulnerable systems with little or no help from users. Among the critical patches is an update for Internet Explorer versions 9 and 10 (Redmond says these flaws are not present in earlier versions of IE).

Other critical patches address issues with the Windows kernel, Microsoft Word, and Microsoft Exchange Server. The final critical bug is a file handling vulnerability in Windows XP, Vista and 7 that Microsoft said could allow remote code execution if a user browses to a folder that contains a file or subfolder with a specially crafted name. Yikes. Updates are available through Windows Update or via Automatic Updates.

Microsoft Patches Windows, Office Flaws

Microsoft today pushed out seven updates to fix a variety of security issues in Windows, Microsoft Office and other software. If you’re using Windows, take a moment to check with Windows Update or Automatic Update to see if new security patches are available.

Most of the vulnerabilities addressed in this month’s patch batch apply to business applications, such as Microsoft Sharepoint, Microsoft SQL Server and Fast Search Server. The lone “critical” update (MS12-064) plugs two security holes in Microsoft Word, and applies to all versions of Microsoft Office. Another patch (MS12-069) fixes a denial-of-service vulnerability in Windows 7 and Windows 2008.

In addition, Microsoft also has shipped an update (KB2758994) for the version of Adobe‘s Flash Player plugin that comes bundled with Windows 8 and Windows 2012 Server.

Also, if you haven’t yet installed the Flash Player update that Adobe released yesterday, now would be a great time to take care of that.

Critical Security Fixes from Adobe, Microsoft

Adobe and Microsoft each issued security updates today to fix critical vulnerabilities in their software. Adobe’s fixes include a patch for a Flash Player flaw that is actively being exploited to break into Windows computers. Microsoft’s Patch Tuesday release includes nine patch bundles — more than half of them rated critical — addressing at least 27 security holes in Windows and related software.

The most pressing of the updates Adobe released today is the Flash Player patch, which fixes a critical flaw (CVE-2012-1535) in the ubiquitous media player software. Adobe says there are reports that the vulnerability is being exploited in the wild in limited targeted attacks, distributed through a malicious Microsoft Word document. The exploit targets the ActiveX version of Flash Player for Internet Explorer on Windows.

Flash Player Update Nixes Zero-Day Flaw

Adobe has issued a critical security update for its ubiquitous Flash Player software. The patch plugs at least seven security holes, including one reported by Google that is already being used to trick users into clicking on malicious links delivered via email.

In an advisory released Wednesday afternoon, Adobe warned that one of the flaws — a cross-site scripting vulnerability (CVE-2012-0767) reported by Google –  was being used in the wild in active, targeted attacks designed to trick users into clicking on a malicious link delivered in an email message. The company said the flaw could be used to take actions on a user’s behalf on any website or webmail provider, if the user visits a malicious website. A spokesperson for the company said this particular attack only works against Internet Explorer on Windows.

Critical Flash Update Plugs 12 Security Holes

Adobe has issued a critical software update for its Flash Player software that fixes at least a dozen security vulnerabilities in the widely-used program. Updates are available for Windows, Mac, LinuxSolaris and Android versions of Flash and Adobe Air.

The update fixes flaws present in Flash Player versions 11.0.1.152 and earlier for Windows, Mac, Linux and Solaris systems, and in Flash 11.0.1.153 and earlier for Android. The vulnerabilities are rated critical, meaning they could give hacked or malicious Web sites an easy way to install software on your machine.

Adobe’s advisory says users of Flash version 11.0.1.152 and earlier should update to v. 11.1.102.55; those using Flash v. 11.0.1.153 and earlier versions for Android should update to Flash Player 11.1.102.59. Users of AIR 3.0 for Windows, Macintosh, and Android should update to AIR  v. 3.1.0.4880. The company says it is not aware of any active attacks against these flaws at this time.

Flash Player Patch Fixes Zero-Day Flaw

Adobe released an emergency security update today to fix a vulnerability that the company warned is being actively exploited in targeted attacks designed to trick the user into clicking on a malicious link delivered in an email message.

The vulnerability — a cross-site scripting bug that could be used to take actions on a user’s behalf on any Web site or Webmail provider, exists in Flash Player version 10.3.181.16 and earlier for Windows, Macintosh, Linux and Solaris. Adobe recommends users update to version 10.3.181.22 (on Internet Explorer, the latest, patched version is 10.3.181.23).  To find out what version of Flash you have, go here.

Google appears to have already pushed out an update that fixes this flaw in Chrome. Adobe says it will ship an update to fix this flaw on Android sometime this week.

Adobe said it is still investigating whether this is exploitable in Adobe Reader and Acrobat X (10.0.2) and earlier 10.x and 9.x versions of Adobe Reader and Acrobat for Windows and Macintosh operating systems, and that it is not aware of any attacks targeting Adobe Reader or Acrobat in the wild.

Remember that if you use Internet Explorer in addition to other browsers, you will need to apply this update twice: Once to install the Flash Active X plugin for IE, and again to update other browsers, such as Firefox and Opera. Updates are available by browsing with the appropriate browser to the Flash Player Download Center. Bear in mind that updating via the Download Center involves installing Adobe’s Download Manager, which may try to foist additional software. If you’d prefer to update manually, the direct installers for Windows are available at this link. If you run into problems installing this update, you’ll want to uninstall previous versions of Flash Player and then try again.

Critical Flash Player Update Plugs 11 Holes

Adobe has released another batch of security updates for its ubiquitous Flash Player software. This “critical” patch fixes at least 11 vulnerabilities, including one that reports suggest is being exploited in targeted email attacks.

In the advisory that accompanies this update, Adobe said “there are reports of malware attempting to exploit one of the vulnerabilities, CVE-2011-0627, in the wild via a Flash (.swf) file embedded in a Microsoft Word (.doc) or Microsoft Excel (.xls) file delivered as an email attachment targeting the Windows platform. However, to date, Adobe has not obtained a sample that successfully completes an attack.”

The vulnerabilities exist in Flash versions 10.2.159.1 and earlier for Windows, Mac, Linux and Solaris. To learn which version of Flash you have, visit this link. The new version for most platforms is 10.3.181.14; Android users should upgrade to Flash Player 10.3.185.21 available by browsing to the Android Marketplace on an Android phone; Google appears to have updated Chrome users automatically with this version of Flash back on May 6 (Chrome versions 11.0.696.68 and later have the newest Flash version).

Time to Patch Your Flash

If it seems like you just updated your Flash Player software to plug a security hole that attackers were using to break into computers, you’re probably not imagining things: Three weeks ago, Adobe rushed out a new version to sew up a critical new security flaw. Today, Adobe issued a critical Flash update to eliminate another dangerous security hole that criminals are actively exploiting.

This new update addresses a vulnerability first detailed here at KrebsOnSecurity.com on Tuesday, and Adobe deserves credit for responding quickly with a patch. But there are few things that are simple about updating Flash, which ships in a dizzying array of version numbers and for many users must be deployed at least twice to cover all browsers. In addition, users may have to uninstall the existing version before updating to guarantee a trouble-free install. Also, Adobe Air will need to be updated if that software also is already installed. Finally, fixing this same vulnerability in Adobe Reader and Acrobat will require installing another patch, which won’t be out for at least another 10 days.

Adobe: Attacks on Flash Player Flaw

Adobe warned today attackers are exploiting a previously unknown security flaw in all supported versions of its Flash Player software. The company said the same vulnerability exists in Adobe Reader and Acrobat, but that it hasn’t yet seen attacks targeting the flaw in those programs.

In an advisory released today, Adobe said malicious hackers were exploiting a critical security hole in Flash (up to and including the latest version of Flash. The software maker warned the vulnerability also exists in Adobe Flash player 10.2.152.33 and earlier versions for Windows, Mac, Linux and Solaris operating systems (10.2.154.13 and earlier for Chrome users), Flash Player 101.106.16 and earlier for Android. In addition, Adobe believes the bug lives in the “authplay.dll” component that ships with Adobe Reader and Acrobat X (10.0.1) and earlier 10.x and 9.x versions for Windows and Mac systems.

Adobe warns that the security hole is currently being exploited via Flash (.swf) files embedded in a Microsoft Excel document delivered as an email attachment. Why someone would need to embed a Flash file in an Excel document is anyone’s guess.
