Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
The CGI module in Ruby can be sent into an infinite loop, resulting in |
| 19 |
a Denial of Service condition. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Ruby is an interpreted scripting language for quick and easy |
| 25 |
object-oriented programming. Ruby's CGI module can be used to build web |
| 26 |
applications. |
| 27 |
|
| 28 |
Affected packages |

Description |
| 38 |
=========== |
| 39 |
|
| 40 |
Ruby's developers found and fixed an issue in the CGI module that can |
| 41 |
be triggered remotely and cause an infinite loop. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A remote attacker could trigger the vulnerability through an exposed |
| 47 |
Ruby web application and cause the server to use unnecessary CPU |
| 48 |
resources, potentially resulting in a Denial of Service. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All Ruby 1.6.x users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=dev-lang/ruby-1.6.8-r12" |
| 62 |
|
| 63 |
All Ruby 1.8.x users should upgrade to the latest version: |
