Local exploitation of an insecure file and directory permissions vulnerability in Adobe Systems Inc.'s Macromedia ColdFusion MX 7 may allow an attacker to execute code with root privileges.

A patch was recently released to fix the vulnerabilities referenced in the Adobe Security Advisory APSB06-17. This patch was intended to correct insecure file permissions of multiple files within the Verity sub-directory of ColdFusion. Unfortunately, the patch archive creates an additional vulnerability.
