Hi,

The following vulnerability was published for imagemagick.

CVE-2019-11472[0]:
| ReadXWDImage in coders/xwd.c in the XWD image parsing component of
| ImageMagick 7.0.8-41 Q16 allows attackers to cause a denial-of-service
| (divide-by-zero error) by crafting an XWD image file in which the
| header indicates neither LSB first nor MSB first.

Although [2] would not directly apply, if I did not do any mistake,
then the issue is as well present in 8:6.9.10.23+dfsg-2 already. But
please double-check.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
