CVE-2006-6565: Filezilla-Project Filezilla Server

Medium severity, CVSS 4.0. EPSS: 70.6% chance of exploitation in the next 30 days.

FileZilla Server before 0.9.22 allows remote attackers to cause a denial of service (crash) via a wildcard argument to the (1) LIST or (2) NLST commands, which results in a NULL pointer dereference, a different set of vectors than CVE-2006-6564. NOTE: CVE analysis suggests that the problem might be due to a malformed PORT command.
