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. NOTE: some of these details are obtained from third party information.

Buffer overflow in the parsecmd function in bftpd before 1.8 has unknown impact and attack vectors related to the confstr variable.
