Opera: Multiple spoofing vulnerabilities

Opera: Multiple spoofing vulnerabilities Opera contains three vulnerabilities, allowing an attacker to impersonate legitimate websites with URI obfuscation or to spoof websites with frame injection. opera 2004-07-20 2004-07-20 56311 56109 remote 7.53 7.52

Opera is a multi-platform web browser.

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.

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.

There is no known workaround at this time. All users are encouraged to upgrade to the latest available version.

All Opera users should upgrade to the latest stable version:


    # emerge sync

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