Description

ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to 7.1.2-0 and 6.9.13-26, in ImageMagick's `magick stream` command, specifying multiple consecutive `%d` format specifiers in a filename template causes a memory leak. Versions 7.1.2-0 and 6.9.13-26 fix the issue.

Affected products

ImageMagick: before 6.9.13-26; from 7.0.0-0 before 7.1.2-0 — fixed in 6.9.13-26, 7.1.2-0

How to fix

Upgrade to a fixed version: ImageMagick 6.9.13-26, 7.1.2-0. Check the vendor advisory for mitigations.
