Descriptions

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.

La función WritePALMImage() en el archivo /coders/palm.c usó conversiones size_t en varias áreas de un cálculo que podría conllevar a valores fuera del rango de comportamiento indefinido de tipo representable "unsigned long" cuando un archivo de entrada diseñado 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 marcó la gravedad como baja porque, aunque podría generar un impacto en la disponibilidad de la aplicación, no se mostró un impacto específico en este caso. Este fallo afecta a ImageMagick versiones anteriores a 7.0.9-0
