The installed version of Firefox 3.6.x is earlier than 3.6.27 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.
