CVE-2012-5380

DISPUTED 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.
