Ubuntu 4.10 / 5.04 / 5.10 : heimdal vulnerability (USN-247-1)
Low Nessus Plugin ID 21055
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionA privilege escalation flaw has been found in the heimdal rsh (remote shell) server. This allowed an authenticated attacker to overwrite arbitrary files and gain ownership of them.
Please note that the heimdal-servers package is not officially supported in Ubuntu (it is in the 'universe' component of the archive). However, this affects you if you use a customized version built from the heimdal source package (which is supported).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected packages.
