Description Pedro Sampaio 2017-09-05 12:05:31 UTC 
The ReadJNGImage and ReadOneJNGImage functions in coders/png.c in
GraphicsMagick 1.3.26 do not properly manage image pointers after
certain error conditions, which allows remote attackers to conduct
use-after-free attacks via a crafted file, related to a ReadMNGImage
out-of-order CloseBlob call. 

NOTE: this vulnerability exists because of
an incomplete fix for CVE-2017-11403.
