Description Josh Bressers 2007-03-10 00:58:49 UTC 
+++ This bug was initially created as a clone of Bug #231693 +++

A bug recently showed up in the Debian BTS that describes an integer overflow in
X's XGetPixel() function

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=414045

The report incorrectly states it is a buffer overflow.  The bug also has a
proposed patch and reproducer for this flaw.

The issue is that the XInitImage() function allows the caller to supply silly
values, which can cause several integer overflow.  A call to XGetPixel() can
also result in integer overflows.  While one would expect the calling
application to sanitize the data passed to XInitImage(), the library should also
be smart enough to prevent the caller from giving it bad data.
