Synopsis :

The remote Ubuntu host is missing a security-related patch.

this issue to execute arbitrary code as their user, possibly bypassing
shell or command restrictions.

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.
