Synopsis
========
Opera contains three vulnerabilities, allowing an attacker to
impersonate legitimate websites with URI obfuscation or to spoof
websites with frame injection.
Background
==========
Opera is a multi-platform web browser.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-www/opera <= 7.52 >= 7.53
Description
===========
Opera fails to remove illegal characters from an URI of a link and to
check that the target frame of a link belongs to the same website as
the link. Opera also updates the address bar before loading a page.
Additionally, Opera contains a certificate verification problem.
Impact
======
These vulnerabilities could allow an attacker to impersonate legitimate
websites to steal sensitive information from users. This could be done
by obfuscating the real URI of a link or by injecting a malicious frame
into an arbitrary frame of another browser window.
Workaround
==========
There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version.
Resolution
==========
All Opera users should upgrade to the latest stable version:
# emerge sync
# emerge -pv ">=net-www/opera-7.53"
# emerge ">=net-www/opera-7.53"
