It's that time of the month again, Patch Tuesday for June! With only eight total bulletins (2 Critical and 6 Important) this Patch Tuesday is surprisingly light compared to months past. What's not surprising is that Internet Explorer is back with another Critical bulletin patching 24 individual CVEs, half of all the vulnerabilities this month. The second Critical bulletin patches a remote code execution vulnerability in Windows Media Player. An attacker could exploit this vulnerability by sending their victim a link that invokes WMP in a specific way that allows the attacker to execute arbitrary code in the context of the logged in victim.
There are two additional RCE bulletins patched this month; one in the Office Suite and the other in Microsoft Common Controls. These vulnerabilities would typically be exploited via malicious attachments on phishing emails. The remaining bulletins are all privilege escalation vulnerabilities.

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. 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.
This security update is rated Critical for Internet Explorer 6 (IE 6) through Internet Explorer 11 (IE 11) on affected Windows clients, and Moderate for Internet Explorer 6 (IE 6) through Internet Explorer 11 (IE 11) on affected Windows servers.
MS15-057
CVE-2015-1728
Critical
Vulnerability in Windows Media Player Could Allow Remote Code Execution
This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if Windows Media Player opens specially crafted media content that is hosted on a malicious website. An attacker who successfully exploited this vulnerability could take complete control of an affected system remotely. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
This security update is rated Critical for Windows Media Player 10 when installed on Windows Server 2003, Windows Media Player 11 when installed on Windows Vista or Windows Server 2008, and Windows Media Player 12 when installed on Windows 7 or Windows Server 2008 R2.

Important
Vulnerabilities in Microsoft Office Could Allow Remote Code Execution
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.
This security update is rated Important for Microsoft Office 2007, Microsoft Office 2010, Microsoft Office 2013, Microsoft Office 2013 RT
MS15-060
CVE-2015-1756
Important
Vulnerability in Microsoft Common Controls Could Allow Remote Code Execution
A remote code execution vulnerability exists in Microsoft Common Controls when it accesses an object in memory that has not been correctly initialized or has been deleted. An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user clicks a specially crafted link, or a link to specially crafted content, and then invokes F12 Developer Tools in Internet Explorer.
This security update is rated Important for all supported editions of Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012, Windows RT, Windows 8.1, Windows Server 2012 R2, and Windows RT 8.1.

Vulnerabilities in Windows Kernel Could Allow Elevation of Privilege
This security update resolves vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow elevation of privilege if an attacker logs on to the system and runs a specially crafted application in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
This security update is rated Important for all supported releases of Windows.
MS15-062
CVE-2015-1757
Important
Vulnerability in Active Directory Federation Services Could Allow Elevation of Privilege
This security update resolves a vulnerability in Microsoft Active Directory Federation Services (AD FS). The vulnerability could allow elevation of privilege if an attacker submits a specially crafted URL to a target site. Due to the vulnerability, in specific situations specially crafted script is not properly sanitized, which subsequently could lead to an attacker-supplied script being run in the security context of a user who views the malicious content. For cross-site scripting attacks, this vulnerability requires that a user be visiting a compromised site for any malicious action to occur.
This security update is rated Important for Active Directory Federation Services 2.0 and Active Directory Federation Services 2.1
MS15-063
CVE-2015-1758
Important
Vulnerability in Windows Kernel Could Allow Elevation of Privilege
This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker places a malicious .dll file in a local directory on the machine or on a network share. An attacker would then have to wait for a user to run a program that can load a malicious .dll file, resulting in elevation of privilege.
This security update is rated Important for all supported editions of Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012, and Windows RT.
MS15-064
CVE-2015-1764, CVE-2015-1771, CVE-2015-2359
Important
Vulnerabilities in Microsoft Exchange Server Could Allow Elevation of Privilege
This security update resolves vulnerabilities in Microsoft Exchange Server. The most severe of the vulnerabilities could allow elevation of privilege if an authenticated user clicks a link to a specially crafted webpage. An attacker would typically have to convince users to click a link, typically by way of an enticement in a phishing email or Instant Messenger message.
This security update is rated Important for all supported editions of Microsoft Exchange Server 2013.
