SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionStephane Chazelas discovered that Bash incorrectly handled trailing code in function definitions. An attacker could use this issue to bypass environment restrictions, such as SSH forced command environments.
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 bash package.
