21 Background
22 ==========

24 The Hewlett-Packard Linux Imaging and Printing system (HPLIP) provides
25 drivers for HP's inkjet and laser printers, scanners and fax machines.
26 It integrates with the Common UNIX Printing System (CUPS) and Scanner
27 Access Now Easy (SANE).

38 Description
39 ===========
40
41 Kees Cook from the Ubuntu Security team discovered that the hpssd
42 daemon does not correctly validate user supplied data before passing it
43 to a "popen3()" call.
44
45 Impact
46 ======
47
48 A local attacker may be able to exploit this vulnerability by sending a
49 specially crafted request to the hpssd daemon to execute arbitrary
50 commands with the privileges of the user running hpssd, usually root.

52 Workaround
53 ==========
54
55 There is no known workaround at this time.
56
57 Resolution
58 ==========

60 All HPLIP users should upgrade to the latest version:
61
62 # emerge --sync
63 # emerge --ask --oneshot --verbose "net-print/hplip"
