The installed version of Thunderbird 3.1.x is earlier than 3.1.19 and is, therefore, potentially affected by an integer overflow vulnerability in libpng, a library used by this application. When decompressing certain PNG image files, this could be exploited to crash the application or even execute arbitrary code.
