Microsoft and Adobe release patches to fix critical vulnerabilities

(LiveHacking.Com) – For March’s Patch Tuesday Microsoft has released seven bulletins, four Critical-class and three Important-class. The bulletins address 20 vulnerabilities in total across several Microsoft products including Windows, Office, Internet Explorer, Server Tools, and Silverlight. Likewise Adobe has released a security update for its popular Flash Player to address vulnerabilities that could potentially allow a hacker to take control of a vulnerable system.

Microsoft

Among the fixes is a patch for an issue in the Kernel-Mode Drivers (KMD) where an attacker could gain administrator privileges by inserting a malicious USB flash drive into a Windows machine. Since the attack works even when no user is currently logged on, it means that anyone with casual access, such as a security guard, office cleaner or anyone with access to office space, could simply plug in a USB flash drive into a PC and perform any action as an administrator. In total MS13-027 resolves three privately reported vulnerabilities correcting the way that a Windows kernel-mode USB drivers handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode.

Nine issues have also been fixed in Internet Explorer. The most severe of these could allow remote code execution if a user views a specially crafted webpage using IE. Upon successful exploit An attacker could gain the same rights as the current owner. All but one of these issues were privately reported to Microsoft and there are no reports of these vulnerabilities being used in the wild.

Microsoft Silverlight has also been patched to fix a vulnerability that could allow remote code execution if an attacker hosts a website that contains a specially crafted Silverlight application. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements.
