Farewell to Flash: July’s Patch Tuesday Updates

By July 14, 2015June 22nd, 2022No Comments

Zero Day (0-Day) – Adobe released yet another zero day update for their Flash plugin today. This is more serious than last month since Mozilla is ready to stop supporting Flash. As Mark Schmidt, head of Firefox Support, announced earlier today: “All versions of Flash are now blocked by default in Firefox.” He also said, “Nothing relies on Flash as much as malware.” Could this be the beginning of the end for the Flash plugin.

You will also notice this month includes last month’s pulled patch “MS15-058.” Due to the heightened exposure of this vulnerability and despite its Important rating, increased testing should be conducted before deploying. After all, we don’t know why it was really pulled from June’s release.

A big thing on this month’s Microsoft release is the end-of-life for Windows Server 2003. After this month, it is not guaranteed any further security updates will be available. We encourage our customers to verify their environment is safe as possible by either ensuring all servers are patched or migrating to a supported server operating system.

All content from the following table will be added into Syxsense shortly. We recommend our clients consider the following updates for their remediation cycle this month: MS15-058, MS15-067, MS15-065, MS15-066, MS15-069 and MS15-070 by combining the vendor severity, the independent CVSS score and their current exposure. The most important update in this release is MS15-067 due to the CVSS score of 10. This is the highest and the most likely to impact our customers.

The CVSS scores range from 0 to 10. Vulnerabilities with a base score in the range 7.0-10.0 are High, those in the range 4.0-6.9 as Medium, and 0-3.9 as Low.

MS15-058

Vulnerabilities in SQL Server Could Allow Remote Code Execution (3065718)

This security update resolves vulnerabilities in Microsoft SQL Server. The most severe vulnerabilities could allow remote code execution if an authenticated attacker runs a specially crafted query that is designed to execute a virtual function from a wrong address, leading to a function call to uninitialized memory. To exploit this vulnerability an attacker would need permissions to create or modify a database.

MS15-065

Security Update for Internet Explorer (3076321)

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. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

MS15-066

Vulnerability in VBScript Scripting Engine Could Allow Remote Code Execution (3072604)

This security update resolves a vulnerability in the VBScript scripting engine in Microsoft Windows. The vulnerability could allow remote code execution if a user visits a specially crafted website. An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

Remote Code Execution

Critical

MS15-067

Vulnerability in RDP Could Allow Remote Code Execution (3073094)

This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if an attacker sends a specially crafted sequence of packets to a targeted system with Remote Desktop Protocol (RDP) enabled. By default, RDP is not enabled on any Windows operating system. Systems that do not have RDP enabled are not at risk.

Remote Code Execution

Critical

MS15-068

Vulnerabilities in Windows Hyper-V Could Allow Remote Code Execution (3072000)

This security update resolves vulnerabilities in Microsoft Windows. The vulnerabilities could allow remote code execution in a host context if a specially crafted application is run by an authenticated and privileged user on a guest virtual machine hosted by Hyper-V. An attacker must have valid logon credentials for a guest virtual machine to exploit this vulnerability.

Remote Code Execution

Critical

7.7

MS15-069

Vulnerabilities in Windows Could Allow Remote Code Execution (3072631)

This security update resolves vulnerabilities in Microsoft Windows. The vulnerabilities could allow Remote Code Execution if an attacker first places a specially crafted dynamic link library (DLL) file in the target user’s current working directory and then convinces the user to open an RTF file or to launch a program that is designed to load a trusted DLL file but instead loads the attacker’s specially crafted DLL file. An attacker who successfully exploited the vulnerabilities could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

MS15-070

Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (3072620)

This security update resolves vulnerabilities in Microsoft Office. The most severe of the vulnerabilities could allow remote code execution if a user opens a specially crafted Microsoft Office file. An attacker who successfully exploited the vulnerabilities could run arbitrary code in the context of the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
