wenv should be used with caution.
- DO NOT run untrusted code (or DLLs)!
- DO NOT run it with root / super users privileges!
The following problems also directly apply to wenv:
- Wine can in fact theoretically run (some) Windows malware.
- NEVER run Wine as root! See FAQ at WineHQ for details.
wenv does not actively prohibit its use with root privileges.
