Mandrake Linux Security Advisory : leafnode (MDKSA-2005:114)
Medium Nessus Plugin ID 18676
SynopsisThe remote Mandrake Linux host is missing a security update.
DescriptionA number of vulnerabilities in the leafnode NNTP server package have been found :
A vulnerability in the fetchnews program that could under some circumstances cause a wait for input that never arrives, which in turn would cause fetchnews to hang (CVE-2004-2068).
Two vulnerabilities in the fetchnews program can cause fetchnews to crash when the upstream server closes the connection and leafnode is receiving an article header or an article body, which prevent leafnode from querying other servers that are listed after that particular server in the configuration file (CVE-2005-1453).
Finally, another vulnerability in the fetchnews program could also cuase a wait for input that never arrives, causing fetchnews to hang (CVE-2005-1911).
The updated packages have been patched to correct this problem.
SolutionUpdate the affected leafnode package.
