Firefox 3.6.x < 3.6.27 'png_decompress_chunk' Integer Overflow

High Nessus Plugin ID 58006


The remote Windows host contains a web browser that is potentially affected by an integer overflow vulnerability.


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.


Upgrade to Firefox 3.6.27 or later.
