Descriptions

A flaw was found in ImageMagick in coders/hdr.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type `unsigned char`. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to ImageMagick 7.0.8-68.

Se encontró un fallo en ImageMagick en el archivo coders/hdr.c. Un atacante que envía un archivo diseñado que es procesado por ImageMagick podría desencadenar un comportamiento indefinido en la forma de valores fuera de rango de tipo "unsigned char". Lo más probable es que esto afecte la disponibilidad de la aplicación, pero podría causar potencialmente otros problemas relacionados con el comportamiento indefinido. Este fallo afecta a ImageMagick versiones anteriores a 7.0.8-68
