execute arbitrary code. (CVE-2012-0212)

arguments to external commands. If a user or automated system were tricked
into processing specially crafted files, a remote attacher could possibly
execute arbitrary code. (CVE-2012-2240)

Raphael Geissert discovered that the dget tool incorrectly escaped
arguments to external commands. If a user or automated system were tricked

execute arbitrary code. This issue only affected Ubuntu 10.04 LTS and
Ubuntu 11.04. (CVE-2012-2242)
