What is CVE-2012-3524?
CVE-2012-3524 is a medium-severity vulnerability in n/a, published on 18 Sep 2012. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
libdbus 1.5.x and earlier, when used in setuid or other privileged programs in X.org and possibly other products, allows local users to gain privileges and execute arbitrary code via the DBUS_SYSTEM_BUS_ADDRESS environment variable. NOTE: libdbus maintainers state that this is a vulnerability in the applications that do not cleanse environment variables, not in libdbus itself: "we do not support use of libdbus in setuid binaries that do not sanitize their environment before their first call into libdbus."
Weakness: CWE-264
