SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionIsaac Boukris and Andrew Bartlett discovered that Samba incorrectly checked S4U2Self packets. In certain environments, a remote attacker could possibly use this issue to escalate 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.
SolutionUpdate the affected samba package.
