The remote Windows host contains a mail client that is potentially affected by a use-after-free vulnerability.
The installed version of Thunderbird ESR 17.x is potentially affected by a use-after-free vulnerability.

The previously freed memory can be dereferenced and could lead to arbitrary code execution.
