SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionIt was discovered that Bash incorrectly handled the restricted shell.
An attacker could possibly use this issue to escape restrictions and execute any command.
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.
