CVE-2017-11722 (opens in a new tab)How to fix?
Upgrade Alpine:3.6 graphicsmagick to version 1.3.25-r3 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream graphicsmagick package and not the graphicsmagick package as distributed by Alpine.
See How to fix? for Alpine:3.6 relevant fixed versions and status.
The WriteOnePNGImage function in coders/png.c in GraphicsMagick 1.3.26 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted file, because the program's actual control flow was inconsistent with its indentation. This resulted in a logging statement executing outside of a loop, and consequently using an invalid array index corresponding to the loop's exit condition.
