Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
Michal Zalewski has reported a vulnerability in Mozilla Firefox, which can be exploited by malicious people to bypass certain security restrictions.

The vulnerability is caused due to an error in the handling of the "locations.hostname" DOM property. This can be exploited to e.g. manipulate authentication cookies for an arbitrary web site via assigning a URL including a NULL character ("\x00") to "locations.hostname".

Successful exploitation requires that the user is e.g. tricked into visiting a malicious web site.

The vulnerability is reported in version 2.0.0.1. Other versions may also be affected.

NOTE: Other issues have also been reported, some of which are also related to the "locations.hostname" DOM property.
