http://secunia.com/advisories/21866/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, DoS

WHERE:
>From remote

SOFTWARE:
Macromedia ColdFusion MX 7
http://secunia.com/product/4984/

DESCRIPTION:
Two vulnerabilities have been reported in ColdFusion, which can be
exploited by malicious, local users to bypass certain security
restrictions and by malicious people to cause a DoS (Denial of
Service).

1) It is possible to cause an infinite loop in ColdFusion by sending
a specially crafted command to the ColdFusion Flash Remoting
Gateway.

2) An error exists due to CFML templates outside a sandbox being able
to call ColdFusion components within a sandbox in certain situations.

The vulnerabilities have been reported in versions 7 and 7.0.1.

SOLUTION:
Update to version 7.0.2 or apply hotfixes for version 7.0.1:
