Descriptions

The GD Graphics Library (aka LibGD) through 2.3.2 has an out-of-bounds read because of the lack of certain gdGetBuf and gdPutBuf return value checks.

GD Graphics Library (también se conoce como LibGD) versiones hasta 2.3.2, presenta una lectura fuera de límites debido a una falta de ciertas comprobaciones de los valores de retorno de gdGetBuf y gdPutBuf

It was discovered that the GD Graphics Library did not perform proper bounds checking while handling BMP and WebP files. If a user were tricked into opening a specially crafted file, an attacker could possibly use this issue to cause a denial of service.
