Firefox flaw reopens old wounds

A seven-year-old flaw that could let an attacker place malicious content on trusted websites has resurfaced in the most recent Firefox browser, Secunia has warned.

The flaw, which also affects some other Mozilla Foundation programs, lies in the way the software handles frames, which are a way of showing web content in separate parts of the browser window. The applications don't check whether the frames displayed in a single window all originate from the same website, Secunia said in an advisory on Monday. Firefox 1.x, Mozilla 1.7.x and Camino 0.x versions are vulnerable to the flaw, the security monitoring company said.

As a result, an attacker could insert content into a frame on a trusted website, Secunia said. Account holders who believe they are interacting with a frame belonging to an online bank could be tricked into giving up personal information or downloading malicious code, for example. Secunia rated the issue "moderately critical"
