Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The DrawImage function in magick/render.c in GraphicsMagick 1.3.26 does not properly look for pop keywords that are associated with push keywords, which allows remote attackers to cause a denial of service (negative strncpy and application crash) or possibly have unspecified other impact via a crafted file.

Mitigation

Install update from vendor's website.
