Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
Opera contains three vulnerabilities, allowing an attacker to |
| 22 |
impersonate legitimate websites with URI obfuscation or to spoof |
| 23 |
websites with frame injection. |
| 24 |
|
| 25 |
Background |
| 26 |
========== |
| 27 |
|
| 28 |
Opera is a multi-platform web browser. |
| 29 |
|
| 30 |
Affected packages |
| 31 |
================= |
| 32 |
|
| 33 |
------------------------------------------------------------------- |
| 34 |
Package / Vulnerable / Unaffected |
| 35 |
------------------------------------------------------------------- |
| 36 |
1 net-www/opera <= 7.52 >= 7.53 |
| 37 |
|
| 38 |
Description |
| 39 |
=========== |
| 40 |
|
| 41 |
Opera fails to remove illegal characters from an URI of a link and to |
| 42 |
check that the target frame of a link belongs to the same website as |
| 43 |
the link. Opera also updates the address bar before loading a page. |
| 44 |
Additionally, Opera contains a certificate verification problem. |
| 45 |
|
| 46 |
Impact |
| 47 |
====== |
| 48 |
|
| 49 |
These vulnerabilities could allow an attacker to impersonate legitimate |
| 50 |
websites to steal sensitive information from users. This could be done |
| 51 |
by obfuscating the real URI of a link or by injecting a malicious frame |
| 52 |
into an arbitrary frame of another browser window. |
| 53 |
|
| 54 |
Workaround |
| 55 |
========== |
| 56 |
|
| 57 |
There is no known workaround at this time. All users are encouraged to |
| 58 |
upgrade to the latest available version. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
All Opera users should upgrade to the latest stable version: |
| 64 |
|
| 65 |
# emerge sync |
| 66 |
|
| 67 |
# emerge -pv ">=net-www/opera-7.53" |
| 68 |
# emerge ">=net-www/opera-7.53" |
| 69 |
