Security Advisory
CVE-2017-11722
CVE vulnerability detail — eXtreme Datacenter Security Operations
Description
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 programs 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 loops exit condition.
