## Description

Untrusted search path vulnerability in the installation functionality in
Ruby 1.9.3-p194, when installed in the top-level C:\ directory, might allow
local users to gain privileges via a Trojan horse DLL in the C:\Ruby193\bin
directory, which may be added to the PATH system environment variable by an
administrator, as demonstrated by a Trojan horse wlbsctrl.dll file used by
the "IKE and AuthIP IPsec Keying Modules" system service in Windows Vista
SP1, Windows Server 2008 SP2, Windows 7 SP1, and Windows 8 Release Preview.
NOTE: CVE disputes this issue because the unsafe PATH is established only
by a separate administrative action that is not a default part of the Ruby
installation
