NOTE There was a previous issue where the update below failed to install for App-V 4.6 SP3. This problem has been fixed. The KB article and associated files have been updated and republished.
A new hotfix is now available that fixes vulnerabilities in the Detours Library that is used by Microsoft Application Virtualization (App-V). The following versions are affected:
- App-V 5.1
- App-V 5.0 Service Pack 3 (SP3)
- App-V 4.6 SP3
- App-V 4.5 SP2
This vulnerability could allow an attacker to bypass Address Space Layout Randomization (ASLR) and therefore bypass a product's "hooks" by calling directly to the code stub. An attacker could install replacement code stubs that could view, create, change, or delete data.
