Microsoft released 13 security bulletins that patch vulnerabilities in Windows, Internet Explorer, Edge, Office and Exchange.
One of the browser flaws is undergoing an attack.
Two of the bulletins rated critical, MS16-104 and MS16-105, resolve vulnerabilities in Windows, Internet Explorer and Edge. Six of the flaws affect Internet Explorer and Edge web browsers, including CVE-2016-3351, a security hole that allows an attacker to obtain information that could compromise a targeted system.
This information disclosure flaw can end up exploited if the attacker can trick the victim into accessing a malicious or a compromised website hosting an exploit. Microsoft’s advisory showed CVE-2016-3351 has suffered attacks against Internet Explorer users, but provides no further details. If Microsoft learned about the vulnerability from a cybersecurity firm, it’s possible the details of the attack will be made public in the upcoming days.
The other vulnerabilities patched by the MS16-104 and MS16-105 bulletins affect various components and they can lead to information disclosure or remote code execution.
Other critical bulletins for Windows are MS16-106 and MS16-116, which resolve six flaws that can lead to privilege escalation, information disclosure and arbitrary code execution.
MS16-116 fixes CVE-2016-3375, a memory corruption issue caused by the way the Microsoft OLE Automation mechanism and the VBScript scripting engine in Internet Explorer access objects in memory. The flaw, which can end up exploited for remote code execution if the attacker can convince the victim to access a malicious website, can be patched by applying both the MS16-116 and MS16-104 updates.
A critical security bulletin released for Office (MS16-107) addresses ASLR bypass, information disclosure, Outlook spoofing, and remote code execution vulnerabilities.
Three flaws ended up fixed in Microsoft Exchange, including information disclosure, open redirect and privilege escalation issues.
