The vulnerabilities could allow information disclosure if a user views specially crafted PDF content online or opens a specially crafted PDF document. This security update is rated Important for all supported editions of Windows 8.1, Windows Server 2012, Windows RT 8.1, Windows Server 2012 R2, and Windows 10. Affected Software Windows 8.1 Windows Server 2012 Windows Server 2012 R2 Windows RT 8.1 Windows 10 Vulnerability Information Multiple PDF Library Information Disclosure Vulnerabilities Multiple information disclosure vulnerabilities exist in the way that the Windows PDF Library handles objects in memory. An attacker who successfully exploited the vulnerabilities could obtain information to further compromise a target system. In a web-based attack scenario, an attacker could host a website that is used to attempt to exploit the vulnerabilities. Additionally, compromised websites and websites that accept or host user-provided content could contain specially crafted content that could be used to exploit the vulnerabilities. However, in all cases an attacker would have no way to force users to view attacker-controlled content. Instead, an attacker would have to convince users to take action. For example, an attacker could trick users into clicking a link that takes them to the attacker's site. The update addresses the vulnerabilities by correcting how certain functions handle objects in memory. The following table contains links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list: Vulnerability title CVE number Publicly disclosed Exploited PDF Library Information Disclosure Vulnerability CVE-2016-3370 No No PDF Library Information Disclosure Vulnerability CVE-2016-3374 No No - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
