Debian DSA-2216-1 : isc-dhcp - missing input sanitization

Sebastian Krahmer and Marius Tomaschewski discovered that dhclient of isc-dhcp, a DHCP client, is not properly filtering shell meta-characters in certain options in DHCP server responses. These options are reused in an insecure fashion by dhclient scripts. This allows an attacker to execute...

FreeBSD : isc-dhcp-client -- dhclient does not strip or escape shell meta-characters (7e69f00d-632a-11e0-9f3a-001d092480a4)
