The remote Ubuntu host is missing a security-related patch.
USN-1589-1 fixed vulnerabilities in the GNU C Library. One of the
updates exposed a regression in the floating point parser. This update
fixes the problem.
We apologize for the inconvenience.
It was discovered that positional arguments to the printf() family of
functions were not handled properly in the GNU C Library. An attacker
could possibly use this to cause a stack-based buffer overflow,
creating a denial of service or possibly execute arbitrary code.

It was discovered that multiple integer overflows existed in

has attempted to automatically clean and format it as much as possible
without introducing additional issues.
