Vulnerabilities

A remote code execution vulnerability exists when Windows Media Audio Decoder improperly handles objects. An attacker who successfully exploited the vulnerability could take control of an affected system.<br /> There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit a malicious webpage.<br /> The security update addresses the vulnerability by correcting how Windows Media Audio Decoder handles objects.<br />

An elevation of privilege vulnerability exists in the way that the Windows Function Discovery Service handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions.<br /> To exploit the vulnerability, a locally authenticated attacker could run a specially crafted application.<br /> The security update addresses the vulnerability by ensuring the Windows Function Discovery Service properly handles objects in memory.<br />

An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system.<br /> To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to execute code or to elevate user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system.<br /> The update addresses the vulnerability by correcting how the Windows kernel handles objects in memory.<br />

An elevation of privilege vulnerability exists when the Connected User Experiences and Telemetry Service improperly handles file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges on the victim system.<br /> To exploit the vulnerability, an attacker would first have to gain execution on the victim system, then run a specially crafted application.<br /> The security update addresses the vulnerability by correcting how the Connected User Experiences and Telemetry Service handles file operations.<br />

A remote code execution vulnerability exists in Microsoft Excel software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. 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.<br /> Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Excel. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) containing a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file.<br /> The security update addresses the vulnerability by correcting how Microsoft Excel handles objects in memory.<br />

A information disclosure vulnerability exists when TLS components use weak hash algorithms. An attacker who successfully exploited this vulnerability could obtain information to further compromise a users&amp;#39;s encrypted transmission channel.<br /> To exploit the vulnerability, an attacker would have to conduct a man-in-the-middle attack.<br /> The update addresses the vulnerability by correcting how TLS components use hash algorithms.<br />

A remote code execution vulnerability exists when Windows Media Audio Decoder improperly handles objects. An attacker who successfully exploited the vulnerability could take control of an affected system.<br /> There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit a malicious webpage.<br /> The security update addresses the vulnerability by correcting how Windows Media Audio Decoder handles objects.<br />

A tampering vulnerability exists when Microsoft SharePoint Server fails to properly handle profile data. An attacker who successfully exploited this vulnerability could modify a targeted user&amp;#39;s profile data.<br /> To exploit the vulnerability, an attacker would need to be authenticated on an affected SharePoint Server. The attacker would then need to send a specially modified request to the server, targeting a specific user.<br /> The security update addresses the vulnerability by modifying how Microsoft SharePoint Server handles profile data.<br />

An information disclosure vulnerability exists when the Windows kernel improperly initializes objects in memory.<br /> To exploit this vulnerability, an authenticated attacker could run a specially crafted application. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system.<br /> The update addresses the vulnerability by correcting how the Windows kernel initializes objects in memory.<br />

A cross-site-scripting (XSS) vulnerability exists when Microsoft SharePoint Server does not properly sanitize a specially crafted web request to an affected SharePoint server. An authenticated attacker could exploit the vulnerability by sending a specially crafted request to an affected SharePoint server.<br /> The attacker who successfully exploited the vulnerability could then perform cross-site scripting attacks on affected systems and run script in the security context of the current user. The attacks could allow the attacker to read content that the attacker is not authorized to read, use the victim&amp;#39;s identity to take actions on the SharePoint site on behalf of the user, such as change permissions and delete content, and inject malicious content in the browser of the user.<br /> The security update addresses the vulnerability by helping to ensure that SharePoint Server properly sanitizes web requests.<br />

A cross-site-scripting (XSS) vulnerability exists when Microsoft SharePoint Server does not properly sanitize a specially crafted web request to an affected SharePoint server. An authenticated attacker could exploit the vulnerability by sending a specially crafted request to an affected SharePoint server.<br /> The attacker who successfully exploited the vulnerability could then perform cross-site scripting attacks on affected systems and run script in the security context of the current user. The attacks could allow the attacker to read content that the attacker is not authorized to read, use the victim&amp;#39;s identity to take actions on the SharePoint site on behalf of the user, such as change permissions and delete content, and inject malicious content in the browser of the user.<br /> The security update addresses the vulnerability by helping to ensure that SharePoint Server properly sanitizes web requests.<br />

A remote code execution vulnerability exists in Microsoft SharePoint when the software fails to check the source markup of an application package. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the SharePoint application pool and the SharePoint server farm account.<br /> Exploitation of this vulnerability requires that a user uploads a specially crafted SharePoint application package to an affected version of SharePoint.<br /> The security update addresses the vulnerability by correcting how SharePoint checks the source markup of application packages.<br />
