Windows and Mac OS X 10.5 and higher developed by ACD Systems. It was originally

distributed as a 16-bit application for Windows 3.0 and later supplanted by a 32-bit

version for Windows 95.

3) Technical details
============================

Insufficient validation in IDE_ACDStd.apl of specific byte values used as sizes

in the image content when decompressing run-length encoded bitmaps can

be exploited to cause a heap-based buffer overflow via a specially crafted .RLE file.

 
The vulnerabilities are confirmed in version 5.1 (Build 137). Other versions may also be affected.
