Detail

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 the server 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.

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

For the unstable distribution (sid) these problems have been fixed in version 2.6.2-19.

We recommend that you upgrade your wu-ftpd package.

Id Description
14203 WU-FTPD wu_fnmatch() Function File Globbing Remote DoS

WU-FTPD contains a flaw that may allow a remote attacker to cause a Denial of Service condition. The issue is due to the wu_fnmatch function in wu_fnmatch.c not properly sanitizing user input. With a specially crafted glob pattern combined with a large number of wildcard characters (*), an attacker can cause the service to use excessive CPU cycles and exhaust all available resources.
