This signature detects attempts to exploit a known vulnerability against LibGD. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the server.
Integer signedness error in GD Graphics Library 2.1.1 (aka libgd or libgd2) allows remote attackers to cause a denial of service (crash) or potentially execute arbitrary code via crafted compressed gd2 data, which triggers a heap-based buffer overflow.
