Synopsis |

======== |
17 |
|

19 |
commands with root privileges. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
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). |

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. |
51 |
|
52 |
Workaround |
53 |
========== |
54 |
|
55 |
There is no known workaround at this time. |
56 |
|
57 |
Resolution |
58 |
========== |
59 |
|
60 |
All HPLIP users should upgrade to the latest version: |
61 |
|
62 |
# emerge --sync |
63 |
# emerge --ask --oneshot --verbose "net-print/hplip" |
64 |
