See the full blog post here: http://blog.shavlik.com/april-patch-tuesday-2016/ April’s Patch Tuesday is looking and sounding like a spring weather forecast. The forecast is calling for rain, but it turned out to be partly cloudy. There has been some mixed feelings about a newly announced vulnerability, or vulnerabilities as it were, in Samba. Badlock is a vulnerability recently identified in Windows and Samba. There are eight CVEs related to Badlock, categorized as man-in-the-middle and denial-of-service attacks. The primary CVE is CVE-2016-2118. This is a multi-vendor problem, so two CVEs were opened to track for each vendor.

6. News – Badlock
Badlock.org – Described a serious flaw in Samba that would also affect
windows. The CVEs were released yesterday and were a bit
disappointing given the hype put out by SerNet.
The primary vulnerability (CVE-2016-2118) has a base CVSS of 7.1,
which is high, but the vulnerability does not fit the profile of a
vulnerability likely to be exploited.
CVE-2016-0128 is the only CVE relating to Windows (MS16-047). Some
of the other CVEs talk about Windows, but in the context of older
windows OSs and were issues resolved by config changes long ago.

10. MS16-037: Cumulative Security Update for Internet Explorer (3148531)
 Maximum Severity: Critical
 Affected Products: Internet Explorer
 Description: 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 the
vulnerabilities could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker
could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with
full user rights.
 Impact: Remote Code Execution
 Fixes 6 vulnerabilities:
 CVE-2016-0154, CVE-2016-0159, CVE-2016-0160 (Disclosed), CVE-2016-0162, CVE-2016-0164, CVE-2016-0166
 Restart Required: Requires Restart

11. MS16-038: Cumulative Security Update for Microsoft Edge (3148532)

code execution if a user views a specially crafted webpage using Microsoft Edge. An attacker who successfully exploited the vulnerabilities
could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system
could be less impacted than users with administrative user rights.
 Impact: Remote Code Execution
 Fixes 6 vulnerabilities:
 CVE-2016-0154, CVE-2016-0155, CVE-2016-0156, CVE-2016-0157, CVE-2016-0158, CVE-2016-0161

if a user clicks a specially crafted link that could allow an attacker to run malicious code remotely to take control of the user’s system.
However, in all cases an attacker would have no way to force a user to click a specially crafted link. An attacker would have to convince a
user to click the link, typically by way of an enticement in an email or Instant Messenger message.
