MS15-053: Description of the security update for VBScript and JScript 5.7: May 12, 2015

Support for Windows Server 2003 ended on July 14, 2015

Microsoft ended support for Windows Server 2003 on July 14, 2015. This change has affected your software updates and security options. Learn what this means for you and how to stay protected.

Summary
This security update resolves address space layout randomization (ASLR) security feature bypasses in the JScript and VBScript scripting engines in Microsoft Windows. An attacker could use one of these ASLR bypasses together with another vulnerability, such as a remote code execution vulnerability, to more reliably run arbitrary code on a target system. 

The update addresses the ASLR bypasses by helping to make sure that affected versions of JScript and VBScript correctly implement the ASLR security feature.
