+++ This bug was initially created as a clone of Bug #231684 +++ 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.
Patches from the Debian bug were attached to the RHEL 5 clone of this bug -- bug 231694.
