    Microsoft spreads love to all IT administrators this month by addressing 23 vulnerabilities on the 14th of February. The software giant released nine bulletins and fixed critical flaws in Internet Explorer, an error in a runtime library which can be targeted through Windows Media Player, and flaws in the Windows kernel. Four out of the nine bulletins were tagged as Critical by Microsoft.

    One critical update was MS12-010, or a cumulative security update for Internet Explorer which resolves four privately reported vulnerabilities in versions 6 through 9 of Internet Explorer. These vulnerabilities could be used to run malicious code on a user’s system if they visited a malicious web site with Internet Explorer. A similar code execution vulnerability, MS12-013, could by exploited using flaws in the mscvrt.dll runtime library to run malicious code if the user opened a specially crafted video. The two remaining Critical vulnerabilities (MS12-008 and MS12-016) resolve vulnerabilities in the Windows kernel, the .NET Framework, and Silverlight that could similarly be used to run malicious code.

    Among the remaining five Important vulnerabilities are MS12-012 and MS12-014, which fix DLL preloading issues in the Color Control Panel and Indeo codecs, respectively. MS12-011 fixed a privilege escalation flaw in SharePoint.

    Microsoft urged users to immediately install the patches associated with the above bulletins; users can find full technical details from the February summary page. You can view our page on Threat Encyclopedia for respective Trend Micro solutions.

    Users of Deep Security and OfficeScan with Intrusion Defense Firewall (IDF) plug-in can also find updates to their products that will protect them from threats exploiting the vulnerabilities made public today, in advance of IT administrators being able to roll out these patches. The coverage for this month includes all of the vulnerabilities specifically mentioned above.

    Posted in Bad Sites | Comments Off on Microsoft Sends Love on February Patch Tuesday with Nine Advisories

    At a time when the web is flooded with user information and entire platforms are built and run on sharing just about every piece of information about oneself, you have to wonder, “Are we really living in the post-privacy era?”

    For 2012, we believe that the new social networking generation will redefine privacy. Our concept of online privacy constantly changes along with various shifts in technology. Providing information has become so convenient that most people no longer know how much information they reveal and to whom.

    With Data Privacy Day coming up, it’s high time that people all over the world become aware about best online privacy practices. Though most of you may already know, social networking sites track your movements and store valuable information such as photos, links, videos, and everything else they make public. As you increasingly go online for personal transactions like shopping and banking, you’re bound to wonder just how much information you actually expose online.

    The end of online privacy and an era of extreme openness may be the only inevitable conclusion unless you know the implications that the cyberlinked world brings. You should realize that along with the convenience that the Internet brings comes great responsibility. Despite the fact that Data Privacy Day is currently only observed in the United States and Canada, this should not hinder raising awareness on online privacy on a global level.

    For more information on online privacy, please read our latest TrendLabs Digital Life e-Guide, Be Privy To Online Privacy.

    Trend Micro is an official data privacy champion for this year’s Data Privacy Day.

    Microsoft starts the year right by addressing eight vulnerabilities in its January 2012 round of patches. This update includes fixes for one Critical bulletin, while the rest are rated Important.

    This month’s update covers several vulnerabilities in Microsoft Windows, including those found in Windows Object Packager, Windows Media Player, and Windows Object Packager.

    The only bulletin rated Critical was ‘Vulnerabilities in Windows Media Could Allow Remote Code Execution’. The vulnerabilities included in the said bulletin could allow remote code execution when users open a specially-crafted media file.

    Also corrected in this patch Tuesday release is the way Media Player handles specially-crafted MIDI files and the way DirectShow parses media files. This update applies to all versions of Windows, including Windows 7.

    In addition, MS12-006 fixes the BEAST vulnerability in SSL/TLS protocols, which potentially allowed a malicious user to conduct man-in-the-middle attacks on secure traffic.

    Posted in Vulnerabilities | Comments Off on Microsoft Releases 7 Bulletins for First Patch Tuesday of 2012

    Microsoft released 13 bulletins today instead of 14, as announced in the Patch Tuesday announcement some days ago. In their final Patch Tuesday for the year, Microsoft addressed bugs in Windows, Internet Explorer, and Microsoft Office, while adding in a fix for DUQU in the bulletin MS11-087, which is also known as the DUQU zero-day remote code execution flaw. Attackers embedding specially crafted TrueType fonts in documents can exploit this vulnerability in the Windows kernel. MS11-087 was given a ‘Critical’ rating.

    MS11-092 also deserves attention in this security bulletin as it affects Windows Media Player and also allows an attacker remote code execution if a user opens a specially crafted Microsoft Digital Video Recording (.dvr-ms) file. Microsoft also includes fixes for Active Directory, OLE and the Windows kernel.

    To lean more about Microsoft support for the affected software, more details on the security bulletins for December can be found in their official bulletin summary. Users may also refer to our Trend Micro security advisory page.

    Users of Deep Security and OfficeScan with Intrusion Defense Firewall (IDF) plug-in can also find updates to their products that will protect them from threats exploiting the vulnerabilities made public today, in advance of IT administrators being able to roll out these patches to their systems.

    Posted in Vulnerabilities | Comments Off on Microsoft Releases 13 Bulletins to Close 2011

    System administrators are in for a light Patch Tuesday this month as Microsoft released only four bulletins in its monthly security update.

    The Microsoft Security Bulletin Summary for November 2011 tackles and addresses multiple vulnerabilities in Microsoft Windows. According to the notice, one of the bulletins is rated “critical”, while two are rated “important” and remaining one is rated “moderate.”

    Majority of the bulletins apply to newer versions of Windows and require a reboot. The critical bulletin only affects Windows Vista, Windows 7, and Windows 2008 Server R2.

    This Patch Tuesday gave a break to many IT administrators, however the real question on everyone’s mind is zero-day vulnerability related to DUQU. The vulnerability is exploited through a malicious Microsoft Word document. When opened, a zero-day kernel vulnerability is taken advantage of to execute malicious code. Microsoft did not release a patch in this cycle but has already issued a temporary fix for the exploit found here. The advisory provides a workaround by disabling the rendering of embedded TrueType fonts.

    Additionally, Microsoft also raised their concern on the exploitability of MS11-083, giving it an Exploitability Index of “2”. They gave several scenarios wherein the vulnerability is exploited, and eventually used to achieve remote code execution.

    Users are advised to immediately download and apply these patches as soon as possible. For more information regarding this month’s Patch Tuesday release, visit the Trend Micro security advisory page.
