Description

WU-FTPD contains a flaw that may allow a remote attacker to cause a Denial of Service condition. The issue is due to the wu_fnmatch function in wu_fnmatch.c not properly sanitizing user input. With a specially crafted glob pattern combined with a large number of wildcard characters (*), an attacker can cause the service to use excessive CPU cycles and exhaust all available resources.
