The bftpdutmp_log function in bftpdutmp.c in Bftpd before 2.4 does not place a '\0' character at the end of the string value of the ut.bu_host structure member, which might allow remote attackers to cause a denial of service (daemon crash) via unspecified vectors.

Security readout for executives and security teams

CVE-2009-4593 is a Bftpd flaw that may let a remote attacker crash the FTP daemon. The cited record describes missing string termination in logging code before Bftpd 2.4. Business impact is service interruption, not proven data theft or code execution from the supplied evidence. Exposure is likely limited to systems still running Bftpd versions before 2.4, especially FTP services reachable from untrusted networks. The bundle does not identify downstream distributions, appliances, or package names. Treat this as a moderate legacy service availability risk. Prioritize Internet-facing or business-critical FTP servers first. It does not justify emergency response without evidence of exposure or active exploitation. Mitigation focus: Inventory all Bftpd installations and identify versions before 2.4.; Upgrade affected Bftpd instances to version 2.4 or later where available.; Restrict FTP access to trusted networks until vulnerable services are upgraded..
