Mandrake Linux Security Advisory : xinetd (MDKSA-2001:055-1)
Low Nessus Plugin ID 13872
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionA bug exists in xinetd as shipped with Mandrake Linux 8.0 dealing with TCP connections with the WAIT state that prevents linuxconf-web from working properly. As well, xinetd contains a security flaw in which it defaults to a umask of 0. This means that applications using the xinetd umask that do not set permissions themselves (like SWAT, a web configuration tool for Samba), will create world-writable files. This update sets the default umask to 022.
This update forces the TMPDIR to /tmp instead of obtaining it from the root user by default, which uses /root/tmp. As well, this version of xinetd also fixed a possible buffer overflow in the logging code that was reported by zen-parse on bugtraq, but was not mentioned in the previous advisory.
SolutionUpdate the affected xinetd and / or xinetd-ipv6 packages.
