Revision Note: V1.2 (September 19, 2014): Updated the Known Issues entry in the Knowledge Base Article section from "None" to "Yes".
Summary: This security update resolves a privately reported vulnerability in Microsoft .NET Framework. The vulnerability could allow security feature bypass if a user visits a specially crafted website. In a web-browsing attack scenario, an attacker who successfully exploited this vulnerability could bypass the Address Space Layout Randomization (ASLR) security feature, which helps protect users from a broad class of vulnerabilities. The security feature bypass by itself does not allow arbitrary code execution. However, an attacker could use this ASLR bypass vulnerability in conjunction with another vulnerability, such as a remote code execution vulnerability, that could take advantage of the ASLR bypass to run arbitrary code.
