Gentoo Linux Security Advisory

Title: Opera: Multiple spoofing vulnerabilities (GLSA 200407-15)
Severity: normal
Exploitable: remote
Date: July 20, 2004
Bug(s): #56311, #56109
ID: 200407-15

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: www-client/opera
Vulnerable: <= 7.52
Unaffected: >= 7.53
Architectures: All supported architectures


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:
Code:
# emerge sync
# emerge -pv ">=www-client/opera-7.53"
# emerge ">=www-client/opera-7.53"
