We knew that the Microsoft's Valentine's gift to cancel Patch Tuesday on February 14th was only going to be a temporary stay and, sure enough, Patch Tuesday is back and bigger than ever for March. Over all there are 18 bulletins patching a massive 139 unique CVEs. These bulletins are split right down the middle with nine rated as Critical and nine rated as Important. Among the Critical bulletins are remote code execution (RCE) vulnerabilities in the Internet Explorer, Edge browser and Adobe Flash. The Critical list also includes RCE vulnerabilities in the Windows PDF Library, Microsoft Uniscribe. These vulnerabilities can be exploited by being convincing a target to open a malicious document or visit a malicious web site. As always an ongoing Security Awareness training program is critical to protect your organization from social engineering attacks. A particularly nasty Critical bulletin affecting Hyper-V would allow any regular user in a guest operating system to trigger arbitrary code at the host operating system level.
Three zero day vulnerabilities released in February by security researchers are all patched by the Critical bulletins today. This includes the SMB DoS released by Laurent Gaffié as well the two Google Project Zero released. In February Project Zero released a critical vulnerability in IE and Edge (CVE-2017-0037) as well as a critical vulnerability in Microsoft Graphics Component (GDI).
The biggest news is not this Patch Tuesday, but the fact that Patch Tuesday was skipped in February. Even though we've seen specific patches slip to the following month, this was the first time that Microsoft delayed an entire release. That said, there are very few software vendors that have such a well defined and generally agile patching process as Microsoft. While we see zero days leaked on occasion like the SMB DoS or CVE-2017-0037, Microsoft's responsible disclosure program has done a great job of providing patches ahead of exploits. Their MAPP program gives security vendors like Trustwave early insight into their patches in order to provide additional protections for Microsoft customers that can't patch immediately. This has helped secure countless Microsoft users and is not something you see offered by many other major software vendors. All in all, it was an odd and unprecedented step to delay the release, but one that I think will probably benefitted Microsoft customers more than it put them at risk.
Back to this Patch Tuesday, these bulletins cover the gamut of Microsoft products. Client and Server software and operating systems. Some of the bulletins affect systems that are often made public like MS Exchange and IIS. Add in to all of this three zero day vulnerabilities and you've got a super busy week in front of you. So until next month, get patching!

Cumulative Security Update for Internet Explorer
This security update resolves vulnerabilities in Internet Explorer. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited these vulnerabilities could gain the same user rights as the current user.
