    descriptionThe ProFTPD FTP server has problems with memory leaking that could be used in a DoS attack, as reported by Wojciech Purczynski. A memory leak will happen every time a SIZE command was given provided that the scoreboard file is not writable, which is not the case in a default Linux-Mandrake installation. A similar problem also existed with the USER command where every time it was given the server would use more memory. Additionally, some format string vulnerabilities were reported by Przemyslaw Frasunek which have also been fixed.

    descriptionThe following problems have been reported for the version of proftpd in Debian 2.2 (potato) : - There is a memory leak in the SIZE command which can result in a denial of service, as reported by Wojciech Purczynski. This is only a problem if proftpd cannot write to its scoreboard file; the default configuration of proftpd in Debian is not vulnerable. - A similar memory leak affects the USER command, also as reported by Wojciech Purczynski. The proftpd in Debian 2.2 is susceptible to this vulnerability; an attacker can cause the proftpd daemon to crash by exhausting its available memory. - There were some format string vulnerabilities reported by Przemyslaw Frasunek. These are not known to have exploits, but have been corrected as a precaution.
