The cdf_check_stream_offset function in cdf.c in file before 5.19, as used in the Fileinfo component in PHP before 5.4.30 and 5.5.x before 5.5.14, relies on incorrect sector-size data, which allows remote attackers to cause a denial of service (application crash) via a crafted stream offset in a CDF file.

Many around the globe have been following the 2014 FIFA World Cup Brazil™ closely. Regardless of which country you are supporting, many folks have been impressed by the defensive display put on by keeper Tim Howard in a loss against Belgium. It was a great performance highlighting a strong defense – always a good thing to have, be it on the pitch or on your system.

Today we released six security bulletins addressing 29 unique CVE’s. Two bulletins have a maximum severity rating of Critical, three have maximum severity Important, and one is Moderate. We hope that the table below helps you prioritize the deployment of the updates appropriately for your environment. Bulletin Most likely attack vector Max Bulletin Severity Max exploit-ability Likely first 30 days impact Platform mitigations and key notes MS14-037(Internet Explorer) Victim browses to a malicious webpage.

As security professionals, we are trained to think in worst-case scenarios. We run through the land of the theoretical, chasing “what if” scenarios as though they are lightning bugs to be gathered and stashed in a glass jar. Most of time, this type of thinking is absolutely the correct thing for security professionals to do.

Today, we released Security Advisory 2963983 regarding an issue that impacts Internet Explorer. At this time, we are only aware of limited, targeted attacks. This issue allows remote code execution if users visit a malicious website with an affected browser. This would typically occur by an attacker convincing someone to click a link in an email or instant message.

T. S. Elliot once said, “What we call the beginning is often the end. And to make an end is to make a beginning. The end is where we start from.” So as we put one season to bed, let’s start another by looking at the April security updates. Today, we release four bulletins to address 11 CVEs in Microsoft Windows, Internet Explorer and Microsoft Office.

Today we released Security Advisory 2953095 to notify customers of a vulnerability in Microsoft Word. At this time, we are aware of limited, targeted attacks directed at Microsoft Word 2010. An attacker could cause remote code execution if someone was convinced to open a specially crafted Rich Text Format (RTF) file or a specially crafted mail in Microsoft Outlook while using Microsoft Word as the email viewer.

This month we release five bulletins to address 23 unique CVEs in Microsoft Windows, Internet Explorer and Silverlight. If you need to prioritize, the update for Internet Explorer addresses the issue first described in Security Advisory 2934088, so it should be at the top of your list. While that update does warrant your attention, I want to also call out another impactful update.

Today, we released Security Advisory 2934088 regarding an issue that impacts Internet Explorer 9 and 10. Internet Explorer 6, 7, 8 and 11 are not affected. At this time, we are only aware of limited, targeted attacks against Internet Explorer 10. This issue allows remote code execution if users browse to a malicious website with an affected browser.

In addition to today being the security update release, February 11 is officially Safer Internet Day for 2014. This year, we’re asking folks to Do 1 Thing to stay safer online. While you may expect my “Do 1 Thing” recommendation would be to apply security updates, I’m guessing that for readers of this blog, that request would be redundant.
