Medium Nessus Plugin ID 49772
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionMike Roszkowski discovered that the Kerberos KDC did not correctly validate the contents of certain messages. If an authenticated remote attacker sent specially crafted TGS requests, the KDC service would crash, leading to a denial of service.
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.
