7.2
CVSS v3.1
Official Description
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.
Technical Analysis
CVE-2011-1842 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
