Package : libgd2
Version : 2.1.0-5+deb8u14
CVE ID : CVE-2018-14553
Debian Bug : 951287

A vulnerability was discovered in libgd2, the GD graphics library,
whereby an attacker can employ a specific function call sequence to
trigger a NULL pointer dereference, subsequently crash the application
using libgd2, and create a denial of service.

For Debian 8 "Jessie", this problem has been fixed in version
2.1.0-5+deb8u14.

We recommend that you upgrade your libgd2 packages.
