NVD Description

Note: Versions mentioned in the description apply only to the upstream libx11 package and not the libx11 package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

Multiple integer overflows in (1) the XGetPixel function in ImUtil.c in X.Org libx11 before 1.0.3, and (2) XInitImage function in xwd.c for ImageMagick, allow user-assisted remote attackers to cause a denial of service (crash) or obtain sensitive information via crafted images with large or negative values that trigger a buffer overflow.
