Description Martin Prpič 2015-08-28 09:30:50 UTC
The following flaw was reported in FreeImage:

Affected Version: <= 3.17.0
URL : http://freeimage.sourceforge.net/

Description :
An integer overflow issue in the FreeImage project was reported and fixed recently.

Upstream fix: Revision 1.18 


The PluginPCX.cpp file(version 3.17.0) has:

371 unsigned width = header.window[2] - header.window[0] + 1;
372 unsigned height = header.window[3] - header.window[1] + 1;
373 unsigned bitcount = header.bpp * header.planes;

However, it's possible that header.window[2] < header.window[0], and also header.window[3] < header.window[1]. In this 
two cases, width and height can be overflowed. And this can lead further issue in the rest of the code. Take the 
following lines for example:

568 for (x = 0; x < width; x++) {
569 bits[x * 3 + FI_RGBA_RED] = pline[x];
570 }

The write operation on buffer bits can help an attacker to corrupt the heap.
