Description Josh Bressers 2005-03-11 10:21:12 EST
The mozilla applications contain several image decoders for displaying images 
of various formats. Amoung the most common image formats is the Graphic 
Information File (GIF) format. The code for this parser is located in:

mozilla/modules/libpr0n/decoders/gif/GIF2.cpp

A vulnerability exists in the parsing of a Netscape-specific extension block 
that specifies a 32-bit size integer indicating how much image data the 
application should buffer, which is shown (taken from the gif_write() 
function).
