CVE-2011-1842 [高] | Input Validation Bypass（Language-Selector）

dbus_backend/lsd.py in the D-Bus backend in language-selector before 0.6.7 does not validate the arguments to the (1) SetSystemDefaultLangEnv and (2) SetSystemDefaultLanguageEnv functions, which allows local users to gain privileges via shell metacharacters in a string argument, a different vulnerability than CVE-2011-0729.
