CVE-2019-13297

ImageMagick versión 7.0.8-50 Q16, presenta una lectura excesiva del búfer en la región heap de la memoria en el archivo MagickCore/threshold.c en la función AdaptiveThresholdImage porque una altura de cero se maneja inapropiadamente.

A heap-based buffer over-read was discovered in ImageMagick in the way it selects an individual threshold for each pixel based on the range of intensity values in its local neighborhood due to a height of zero mishandle error. Applications compiled against ImageMagick libraries that accept untrustworthy images may be vulnerable to this flaw. An attacker could abuse this flaw by providing a specially crafted image to make the application crash or leak application data.

ImageMagick is an image display and manipulation tool for the X Window System that can read and write multiple image formats. Issues addressed include buffer overflow, denial of service, double free, information leakage, null pointer, out of bounds read, out of bounds write, and use-after-free vulnerabilities.
