Mozilla is working to fix a browser flaw that could give attackers unauthorized access to data on a victim's machine.

The problem is similar to other data leakage flaws found in the open-source browser, according to researcher Gerry Eisenhaur, who first reported the problem on Saturday.

Eisenhaur has posted sample code that reads the contents of a Mozilla Thunderbird preferences file, but he believes that attackers could get access to more information with variations on his attack.
