This signature detects attempts to exploit a known vulnerability in the Postfix Greylisting daemon. A successful exploit with a malicious format string, can lead to arbitrary remote code execution.
It is reported that GLD contains a format string vulnerability. This issue is due to a failure of the application to properly sanitize user-supplied input data prior to using it in a formatted-printing function. Remote attackers may exploit this vulnerability to cause arbitrary machine code to be executed in the context of the affected service. As the service is designed to be run as the superuser, remote attackers may gain superuser privileges on affected computers. GLD version 1.4 is reportedly affected, but prior versions may also be affected.
