vsftpd before 1.2.2, when under heavy load, allows attackers to cause a denial of service (crash) via a SIGCHLD signal during a malloc or free call, which is not re-entrant.
vsftpd 1.1.3 generates different error messages depending on whether or not a valid username exists, which allows remote attackers to identify valid usernames.
