Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Multiple vulnerabilities have been discovered in Opera: |
| 38 |
|
| 39 |
* Opera does not restrict the ability of a framed web page to change |
| 40 |
the address associated with a different frame (CVE-2008-4195). |
| 41 |
|
| 42 |
* Chris Weber (Casaba Security) discovered a Cross-site scripting |
| 43 |
vulnerability (CVE-2008-4196). |
| 44 |
|
| 45 |
* Michael A. Puls II discovered that Opera can produce argument |
| 46 |
strings that contain uninitialized memory, when processing custom |
| 47 |
shortcut and menu commands (CVE-2008-4197). |
| 48 |
|
| 49 |
* Lars Kleinschmidt discovered that Opera, when rendering an HTTP |
| 50 |
page that has loaded an HTTPS page into a frame, displays a padlock |
| 51 |
icon and offers a security information dialog reporting a secure |
| 52 |
connection (CVE-2008-4198). |
| 53 |
|
| 54 |
* Opera does not prevent use of links from web pages to feed source |
| 55 |
files on the local disk (CVE-2008-4199). |
| 56 |
|
| 57 |
* Opera does not ensure that the address field of a news feed |
| 58 |
represents the feed's actual URL (CVE-2008-4200). |
| 59 |
|
| 60 |
* Opera does not check the CRL override upon encountering a |
| 61 |
certificate that lacks a CRL (CVE-2008-4292). |
| 62 |
|
| 63 |
* Chris (Matasano Security) reported that Opera may crash if it is |
| 64 |
redirected by a malicious page to a specially crafted address |
| 65 |
(CVE-2008-4694). |
| 66 |
|
| 67 |
* Nate McFeters reported that Opera runs Java applets in the context |
| 68 |
of the local machine, if that applet has been cached and a page can |
| 69 |
predict the cache path for that applet and load it from the cache |
| 70 |
(CVE-2008-4695). |
| 71 |
|
| 72 |
* Roberto Suggi Liverani (Security-Assessment.com) reported that |
| 73 |
Opera's History Search results does not escape certain constructs |
| 74 |
correctly, allowing for the injection of scripts into the page |
| 75 |
(CVE-2008-4696). |
| 76 |
|
| 77 |
* David Bloom reported that Opera's Fast Forward feature incorrectly |
| 78 |
executes scripts from a page held in a frame in the outermost page |
| 79 |
instead of the page the JavaScript URL was located (CVE-2008-4697). |
| 80 |
|
| 81 |
* David Bloom reported that Opera does not block some scripts when |
| 82 |
previewing a news feed (CVE-2008-4698). |
| 83 |
|
| 84 |
* Opera does not correctly sanitize content when certain parameters |
| 85 |
are passed to Opera's History Search, allowing scripts to be injected |
| 86 |
into the History Search results page (CVE-2008-4794). |
| 87 |
|
| 88 |
* Opera's links panel incorrectly causes scripts from a page held in |
| 89 |
a frame to be executed in the outermost page instead of the page |
| 90 |
where the URL was located (CVE-2008-4795). |
| 91 |
|
| 92 |
Impact |
| 93 |
====== |
| 94 |
|
| 95 |
These vulnerabilties allow remote attackers to execute arbitrary code, |
| 96 |
to run scripts injected into Opera's History Search with elevated |
| 97 |
privileges, to inject arbitrary web script or HTML into web pages, to |
| 98 |
manipulate the address bar, to change Opera's preferences, to determine |
| 99 |
the validity of local filenames, to read cache files, browsing history, |
| 100 |
and subscribed feeds or to conduct other attacks. |
| 101 |
|
| 102 |
Workaround |
| 103 |
========== |
| 104 |
|
| 105 |
There is no known workaround at this time. |
| 106 |
|
| 107 |
Resolution |
| 108 |
========== |
| 109 |
|
| 110 |
All Opera users should upgrade to the latest version: |
| 111 |
|
| 112 |
# emerge --sync |
| 113 |
# emerge --ask --oneshot --verbose ">=www-client/opera-9.62" |
| 114 |
