File descriptors for the signal pipe introduced in version 2.3.4 are leaked into services started from xinetd. The descriptors could be used to talk to xinetd resulting in crashing it entirely. This is usually called a denial of service. This problem has been fixed by the package maintainer in version 2.3.4-1.2 for the current stable distribution (woody) and in version 2.3.7-1 for the unstable distribution (sid). The old stable distribution (potato) is not affected, since it doesn't contain the signal pipe. We recommend that you upgrade your xinetd packages. 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.
