The remote Windows host contains a mail client that is potentially
affected by an integer overflow vulnerability.
The installed version of Thunderbird 3.1.x is earlier than 3.1.19 and
is, therefore, potentially affected by an integer overflow vulnerability.
An integer overflow error exists in 'libpng', a library used by this
application. When decompressing certain PNG image files, this error
can allow a heap-based buffer overflow which can crash the
application or potentially allow code execution.
