Linux-Mandrake Security Update Advisory
Package name: proftpd
Date: February 8th, 2001
Advisory ID: MDKSA-2001:021
Affected versions: 7.2
The 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.
