What to do
Workaround: To ensure that supporting dynamic link libraries (DLLs) are loaded from system locations prior to the user's current working directory, an administrator can verify SafeDLLSearchMode is enabled in the Windows Registry. This process is outlined in Deployment Guide for Cisco Directory Connector. Warning: Incorrectly modifying the system registry of a Microsoft Windows-based device may cause serious problems. Neither Cisco nor Microsoft can guarantee that problems that may result from improper registry modification, either from applying registry changes via a .reg file or by using the Registry Editor, can be resolved. Modify the registry of a system at the user's own risk.
Exploitation: The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory.
