Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Lack of URL validation in Opera command-line wrapper could be abused to |

Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Peter Zelezny discovered that the shell script used to launch Opera |
| 38 |
parses shell commands that are enclosed within backticks in the URL |
| 39 |
provided via the command line. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
A remote attacker could exploit this vulnerability by enticing a user |
| 45 |
to follow a specially crafted URL from a tool that uses Opera to open |
| 46 |
URLs, resulting in the execution of arbitrary commands on the targeted |
| 47 |
machine. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
There is no known workaround at this time. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All Opera users should upgrade to the latest version: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose ">=www-client/opera-8.51" |
| 61 |
