CVE-2015-7674: Buffer Overflow
First published: Mon Oct 26 2015(Updated: )
Integer overflow in the pixops_scale_nearest function in pixops/pixops.c in gdk-pixbuf before 2.32.1 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted GIF image file, which triggers a heap-based buffer overflow.
