Oracle Linux: CVE-2019-13295: ELSA-2020-1180: ImageMagick security, bug fix, and enhancement update (MODERATE) (Multiple Advisories)

ImageMagick 7.0.8-50 Q16 has a heap-based buffer over-read at MagickCore/threshold.c in AdaptiveThresholdImage because a width of zero is mishandled.
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 width 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.
