Mozilla Firefox and SeaMonkey Gopher Parser Cross Site Scripting Vulnerability

Mozilla Firefox and SeaMonkey are prone to a cross-site scripting vulnerability because they fail to sufficiently sanitize user-supplied data.

An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and to launch other attacks.

This issue affects versions prior to:
Firefox 3.6.11
Firefox 3.5.14
SeaMonkey 2.0.9

NOTE: This issue was previously discussed in 44228 (Mozilla Firefox/Thunderbird/SeaMonkey MFSA 2010-64/65/66/67/68/69/71/72 Multiple Vulnerabilities) but has been given its own record to better document it.
