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 β€˜Jessie’, this problem has been fixed in version 2.1.0-5+deb8u14.

We recommend that you upgrade your libgd2 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
