Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
Several new vulnerabilities were found and fixed in Opera, including |
| 22 |
one allowing an attacker to read the local filesystem remotely. |
| 23 |
|
| 24 |
Background |
| 25 |
========== |
| 26 |
|
| 27 |
Opera is a multi-platform web browser. |
| 28 |
|
| 29 |

Description |
| 38 |
=========== |
| 39 |
|
| 40 |
Multiple vulnerabilities have been found in the Opera web browser. |
| 41 |
Opera fails to deny write access to the "location" browser object. An |
| 42 |
attacker can overwrite methods in this object and gain script access to |
| 43 |
any page that uses one of these methods. Furthermore, access to file:// |
| 44 |
URLs is possible even from pages loaded using other protocols. Finally, |
| 45 |
spoofing a legitimate web page is still possible, despite the fixes |
| 46 |
announced in GLSA 200407-15. |
| 47 |
|
| 48 |
Impact |
| 49 |
====== |
| 50 |
|
| 51 |
By enticing an user to visit specially crafted web pages, an attacker |
| 52 |
can read files located on the victim's file system, read emails written |
| 53 |
or received by M2, Opera's mail program, steal cookies, spoof URLs, |
| 54 |
track user browsing history, etc. |
| 55 |
|
| 56 |
Workaround |
| 57 |
========== |
| 58 |
|
| 59 |
There is no known workaround at this time. All users are encouraged to |
| 60 |
upgrade to the latest available version. |
| 61 |
|
| 62 |
Resolution |
| 63 |
========== |
| 64 |
|
| 65 |
All Opera users should upgrade to the latest stable version: |
| 66 |
|
| 67 |
# emerge sync |
| 68 |
|
| 69 |
# emerge -pv ">=net-www/opera-7.54" |
| 70 |
# emerge ">=net-www/opera-7.54" |
| 71 |
