Patch Tuesday

The H-Security: Next week’s Patch Tuesday sees Microsoft planning to publish a total of six bulletins, including one that addresses a critical vulnerability in all versions of Windows from Windows XP service pack 3 to Windows 7 service pack 1 and Windows Server 2008 R2. The rating means that the hole enables attackers to infect a system via the internet and inject malicious code. Other bulletins will address a privilege elevation flaw which affects the same span of Windows versions. ...

The H-Online: As expected, Microsoft has released nine bulletins to close a total of 21 holes in its products. Four of the bulletins close critical vulnerabilities in Windows, Internet Explorer, .NET and Silverlight, including an issue in the Windows kernel-mode drivers that became publicly known in December of last year. The company advises those responsible for prioritizing update deployment to focus on the critical patches for Internet Explorer and the C Runtime Library in Windows, as these could be exploited by an attacker to remotely execute arbitrary code on a victim’s system. For an attack to be successful, a user must first visit a malicious web page or open a specially crafted file. The other critical bulletins fix issues in .NET and Silverlight, as well as the Windows kernel. Microsoft notes that it has yet to see any active attacks exploiting these issues in the wild. ...

Hey Admins…. It’s that time again. The second Tuesday is upon us and May so far hasn’t been demanding as far as patching goes. So far …. this month Microsoft has only issued two security announcements. MS10-030 and MS10-031. Microsoft has rated both as critical – and both could result in remote code being executed. MS10-030 resolves an integer overflow in POP3 & IMAP mail responses to Outlook Express and Windows Mail…. MS10-031 addresses a stack memory corruption related to the way that “Visual Basic for Applications” searches for ActiveX components, when host applications provide specially crafted files to the Visual Basic runtime. ...

Many patches are announced for tomorrow: The Redmond company expects to release 11 security bulletins. Of those 5 are rated critical, 5 important and 1 moderate. The patches belonging to the bulletins will close 25 security vulnerabilities in Windows, Exchange and in Office. Adobe plans to deliver security updates for critical vulnerabilities in Adobe Reader and Acrobat for all supported platforms tomorrow. Additionally, the automatic updater will be activated with the patches so in future updates get installed silent.

Adobe has announced that it will release an updater along with Adobe Reader and Acrobat versions 9.3.2 and 8.2.2 on patch Tuesday next week. On the Adobe blog, Steve Gottwals wrote: “…we have been testing a new updater technology with select beta customers since our October 13, 2009 quarterly update. The purpose of the new updater is to keep end-users up-to-date in a much more streamlined and automated way. “During our quarterly update on January 12, 2010, and then again for an out-of-cycle update on February 16, 2010, we exercised the new updater with our beta testers. This allowed us to test a variety of network configurations encountered on the Internet in order to ensure a robust update experience. That beta process has been a successful one, and we’ve incorporated several positive changes to the end-user experience and system operation. Now, we’re ready for the next phase of deployment.” ...

Microsoft has put the PC-using world on notice that next Tuesday there will be 11 bulletins released addressing 25 vulnerabilities in Windows, Exchange and Office. Jerry Bryant, Group Manager of Microsoft’s Response Communications, said: “I also want to point out to customers that we will be closing the following open Security Advisories with next week’s updates: — Microsoft Security Advisory 981169 – Vulnerability in VBScript could allow remote code execution. ...

Last month, Microsoft sent flowers to a mock funeral for Internet Explorer 6, in a show of support for the ideal that the old browser should be declared defunct worldwide. But for a few years yet, the company is still bound to support the product for those users (generally businesses) who refuse to upgrade it. That’s why new exploits that continue to target old browsers, such as IE6 and IE7, continue to get attention even a full year after the proper security fix — IE8 — has been deployed. ...

Hot on the heels of the Patch Tuesday announcements yesterday, came the announcement of a new zero-day in Internet Explorer (CVE-2010-0806). Whilst checking through some URLs supposedly serving up malicious code to exploit this vulnerability, I noticed a link to some spam runs from earlier in the week. On March 8th SophosLabs saw spam messages attempting to trick the recipient into visiting rogue web pages. Messages used at least two social engineering tricks to lure victims into clicking the malicious link. ...

Exploit code for the the zero-day vulnerability in Internet Explorer has been added to the Metasploit framework. According to an email HD Moore wrote to ZDNet’s Ryan Naraine, the exploit works quite reliable – successful 50% of the times on Windows XP with SP2 and SP3 with IE7 and deactivated Data Execution Prevention (DEP). The security hole got reported yesterday on Microsoft’s March 2010 Patch Tuesday. Drive-by-Download-Exploits are likely to appear now as the Metasploit framework is open source and the exploit can now be abused even by script kiddies. Time to change the default browser – Microsoft just released a new browser choice screen which allows for exactly that!

Hello and welcome to this month’s blog on the Microsoft patch releases. This is a fairly quiet month—the vendor is releasing two bulletins covering a total of eight vulnerabilities. All of the issues are rated “Important” this month: seven affecting Office/Excel and one affecting Movie Maker and Producer. All of the issues are file-based remote code-execution vulnerabilities in the context of the currently logged-in user. Microsoft also released a security advisory (981374) today regarding a publicly disclosed vulnerability affecting Internet Explorer 6 and 7. Limited, targeted attacks exploiting this issue have been detected in the wild. ...

Microsoft has issued an advance notification for Patch Tuesday next week. The company said it expects to issue two patches, one for Windows and one for Office. Both are intended to patch vulnerabilities that could allow remote code execution and both are rated “important.” Microsoft Security Bulletin Advance Notification for March 2010 here.

Security blogger Brian Krebs is reporting that some Windows XP users are reporting blue screen of death on reboot after installing Microsoft’s Tuesday patch KB977165 (MS010–15: “Vulnerabilities in Windows kernel could allow elevation of privilege.”) “Turns out, a non-trivial number of XP users are reporting that their systems suffer from the dreaded Blue Screen of Death (BSoD) and fall into an interminable reboot loop after installing the latest batch of patches from Redmond,” ...

Microsoft has said it will issue an out-of-band patch today for critical vulnerabilities in Internet Explorer that allow remote execution of code. The company said yesterday it would not wait until the February “Patch Tuesday” to fix the vulnerabilities. The much discussed “Aurora” vulnerabilities in IE have been held at least partially responsible for cyber attacks on Google and more then two dozen other major companies. The attacks on Google were aimed at Gmail accounts of dissidents and Google’s source code. The attacks on the other companies were aimed at stealing intellectual property. ...
