this to execute arbitrary code. (CVE-2012-2337)

- An arbitrary file overwrite vulnerability exists in sudo
due to a race condition occurs in post-uninstall during
the upgrade or removal of sudo packages. A local
attacker can exploit this via a symlink attack against
the /var/tmp/nsswitch.conf.bak file, allowing the
attacker write to a specified file. (CVE-2012-3440)
