Mozilla Firefox and SeaMonkey are affected by a URI-spoofing vulnerability because they fail to adequately handle user-supplied data.
An attacker may leverage this issue by inserting arbitrary content to spoof a URI presented to an unsuspecting user. This may lead to a false sense of trust because the victim may be presented with a URI of a seemingly trusted site while interacting with the attacker's malicious site.
Versions *prior to* the following are affected:
Firefox 3.0.11
SeaMonkey 1.1.17
NOTE: This issue was previously covered in BID 35326 (Mozilla Firefox/Thunderbird/SeaMonkey MFSA 2009-24 through -32 Multiple Remote Vulnerabilities), but has been assigned its own record to better document it.
The following example URI is available:
https://www.example.xn--com-edoaaaaaaaaaaaaaaaaaaaaaaaaaaaa.example2.org/
This URI would be decoded as 'www.example.com' followed by multiple 'U+115a' characters and '.example2.org'.
