Name of the Vulnerable Software and Affected Versions: VMware Horizon Client for Windows versions 5.x prior to 5.5.0

Description: The issue is related to insufficient protection of registration data, which may allow a malicious attacker to gain unauthorized access to protected information. Specifically, if the client crashes, an attacker with local privileges on the machine where Horizon Client for Windows is installed may be able to retrieve hashed credentials.

Recommendations: For versions 5.x prior to 5.5.0, update to version 5.5.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the client to minimize the risk of exploitation.
