#Ms detours update#

This security update addresses the ASLR bypass by correcting how App-V components handle memory addresses. Workstations are primarily vulnerable to the potential ASLR bypass. To exploit the ASLR bypass, an attacker would have to log on to an affected system and run a specially crafted application.

However, an attacker could use the ASLR bypass together with another vulnerability, such as a remote code execution vulnerability, that could use the ASLR bypass to run arbitrary code. The ASLR bypass by itself does not allow arbitrary code execution. This mechanism helps protect users from a broad range of vulnerabilities. This could cause an Address Space Layout Randomization (ASLR) bypass.Īn attacker who successfully exploits the information disclosure vulnerability could use the obtained information to bypass the ASLR security mechanism in Windows. The affected versions are the following:Īn information disclosure vulnerability exists in the way that App-V handles objects in memory. This hotfix fixes vulnerabilities in the Detours Library that's used by Microsoft Application Virtualization (App-V).
