Descriptions
In /MagickCore/statistic.c, there are several areas in ApplyEvaluateOperator() where a size_t cast should have been a ssize_t cast, which causes out-of-range values under some circumstances when a crafted input file is processed by ImageMagick. Red Hat Product Security marked this as Low severity 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 6.9.10-69.
En el archivo /MagickCore/statistic.c, presenta varias áreas en la función ApplyEvaluateOperator() donde una conversión size_t debería haber sido una conversión ssize_t, lo que causa valores fuera de rango bajo algunas circunstancias cuando ImageMagick procesa un archivo de entrada diseñado. Red Hat Product Security marcó esto como de gravedad baja porque, aunque podría generar un impacto en la disponibilidad de la aplicación, ningún impacto específico fue mostrado en este caso. Este fallo afecta a las versiones de ImageMagick versiones anteriores a 6.9.10-69
It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into processing a specially crafted file, an attacker could exploit this to cause a denial of service or affect the reliability of the system. The vulnerabilities included memory leaks, buffer overflows, and improper handling of pixel data.
