TITLE:
Mozilla Firefox 2 URI Launching Vulnerability
SECUNIA ADVISORY ID:
SA31120
VERIFY ADVISORY:
http://secunia.com/advisories/31120/
CRITICAL:
Less critical
IMPACT:
Security Bypass, Exposure of sensitive information
WHERE:
From remote
SOFTWARE:
Mozilla Firefox 2.0.x
http://secunia.com/product/12434/
DESCRIPTION:
A vulnerability has been reported in Firefox 2, which can be
exploited by malicious people to bypass certain security
restrictions
and disclose sensitive information.
The problem is that it is possible to open multiple tabs via
pipe
symbols within the URI and can e.g. be exploited to launch
"chrome:"
URIs via the command-line. This can also be exploited to read
files
from a user's system using the "file:" URI but requires that an
attacker is able to place a malicious file in a guessable
location on
a user's system (e.g. in combination with another security
issue).
Successful exploitation requires that the URI is passed to
Firefox
from e.g. another browser and that Firefox is not running.
The vulnerability is reported in versions prior to 2.0.0.16.
SOLUTION:
Update to version 2.0.0.16.
