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:
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.
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.
