Debian DSA-705-1 : wu-ftpd - missing input sanitising

medium Nessus Plugin ID 18010

Synopsis

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

Description

Several denial of service conditions have been discovered in wu-ftpd, the popular FTP daemon. The Common Vulnerabilities and Exposures project identifies the following problems :

 - CAN-2005-0256 Adam Zabrocki discovered a denial of service condition in wu-ftpd that could be exploited by a remote user and cause the server to slow down by resource exhaustion.

 - CAN-2003-0854

 Georgi Guninski discovered that /bin/ls may be called from within wu-ftpd in a way that will result in large memory consumption and hence slow down the server.

Solution

Upgrade the wu-ftpd package.

For the stable distribution (woody) these problems have been fixed in version 2.6.2-3woody5.
