Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Opera contains multiple vulnerabilities, which may allow the execution |
| 19 |
of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Opera is a multi-platform web browser. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|

Package / Vulnerable / Unaffected |

Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Michael A. Puls II discovered an unspecified flaw when launching |
| 38 |
external email or newsgroup clients (CVE-2007-5541). David Bloom |
| 39 |
discovered that when displaying frames from different websites, the |
| 40 |
same-origin policy is not correctly enforced (CVE-2007-5540). |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
An attacker could potentially exploit the first vulnerability to |
| 46 |
execute arbitrary code with the privileges of the user running Opera by |
| 47 |
enticing a user to visit a specially crafted URL. Note that this |
| 48 |
vulnerability requires an external e-mail or newsgroup client |
| 49 |
configured in Opera to be exploitable. The second vulnerability allows |
| 50 |
an attacker to execute arbitrary script code in a user's browser |
| 51 |
session in context of other sites or the theft of browser credentials. |
| 52 |
|
| 53 |
Workaround |
| 54 |
========== |
| 55 |
|
| 56 |
There is no known workaround at this time for all these |
| 57 |
vulnerabilities. |
| 58 |
|
| 59 |
Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
All Opera users should upgrade to the latest version: |
| 63 |
|
| 64 |
# emerge --sync |
| 65 |
# emerge --ask --oneshot --verbose ">=www-client/opera-9.24" |
| 66 |
|
