Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
A vulnerability in CUPS allows remote attackers to cause a denial of |
| 22 |
service when sending a carefully-crafted UDP packet to the IPP port. |
| 23 |
|
| 24 |
Background |
| 25 |
========== |
| 26 |
|
| 27 |
The Common UNIX Printing System (CUPS) is a cross-platform print |
| 28 |
spooler. |
| 29 |
|
| 30 |
Affected packages |
| 31 |

Package / Vulnerable / Unaffected |

Description |
| 39 |
=========== |
| 40 |
|
| 41 |
Alvaro Martinez Echevarria discovered a hole in the CUPS Internet |
| 42 |
Printing Protocol (IPP) implementation that allows remote attackers to |
| 43 |
cause CUPS to stop listening on the IPP port. This can be caused by |
| 44 |
sending an empty UDP datagram packet to the IPP port. |
| 45 |
|
| 46 |
Impact |
| 47 |
====== |
| 48 |
|
| 49 |
A remote user with malicious intent can easily cause a denial of |
| 50 |
service to the CUPS daemon. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All CUPS users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge sync |
| 63 |
|
| 64 |
# emerge -pv ">=net-print/cups-1.1.20-r2" |
| 65 |
# emerge ">=net-print/cups-1.1.20-r2" |
| 66 |
