The vulnerability is caused due to an array indexing error when decompressing image data. This can be exploited to corrupt memory via a specially crafted GIF image containing a large "LZWMinimumCodeSize" value. Successful exploitation may allow execution of arbitrary code, but requires tricking a user into opening a malicious file. The vulnerability is confirmed in version 4.1.0. Other versions may also be affected. SOLUTION: No official solution is currently available. PROVIDED AND/OR DISCOVERED BY: Jean Pascal Pereira Additional information provided by Secunia Research.
