    {

      "value": "WritePALMImage() in /coders/palm.c used size_t casts in several areas of a calculation which could lead to values outside the range of representable type `unsigned long` undefined behavior when a crafted input file was processed by ImageMagick. The patch casts to `ssize_t` instead to avoid this issue. Red Hat Product Security marked the Severity as Low because although it could potentially lead to an impact to application availability, no specific impact was shown in this case. This flaw affects ImageMagick versions prior to ImageMagick 7.0.9-0."

      "value": "La funci\u00f3n WritePALMImage() en el archivo /coders/palm.c us\u00f3 conversiones size_t en varias \u00e1reas de un c\u00e1lculo que podr\u00eda conllevar a valores fuera del rango de comportamiento indefinido de tipo representable \"unsigned long\" cuando un archivo de entrada dise\u00f1ado era procesado por ImageMagick. En su lugar, el parche se convierte en \"ssize_t\" para evitar este problema. La seguridad de productos de Red Hat marc\u00f3 la gravedad como baja porque, aunque podr\u00eda generar un impacto en la disponibilidad de la aplicaci\u00f3n, no se mostr\u00f3 un impacto espec\u00edfico en este caso. Este fallo afecta a ImageMagick versiones anteriores a 7.0.9-0"
