Synopsis
The remote Ubuntu host is missing one or more security-related patches.Description
It was discovered that Kerberos did not correctly handle invalid AES blocks. An unauthenticated remote attacker could send specially crafted traffic that would crash the KDC service, leading to a denial of service, or possibly execute arbitrary code with root privileges.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.
Solution
