Debian DSA-029-2 : proftpd - remote DOS & potential buffer overflow

high Nessus Plugin ID 14866

Synopsis

The remote Debian host is missing a security-related update.

Description

The 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.

Solution

All three of the above vulnerabilities have been corrected in proftpd-1.2.0pre10-2potato1. We recommend you upgrade your proftpd package immediately.
