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. Upgrade Instructions - - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
