Descriptions
In coders/bmp.c in ImageMagick before 7.0.8-16, an input file can result in an infinite loop and hang, with high CPU and memory consumption. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted file.
En coders/bmp.c en ImageMagick en versiones anteriores a la 7.0.8-16, un archivo de entradas puede resultar en un bucle infinito y un bloqueo, con un gran consumo de CPU y memoria. Los atacantes remotos pueden aprovechar esta vulnerabilidad para provocar una denegación de servicio (DoS) mediante un archivo manipulado.
It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program. Due to a large number of issues discovered in GhostScript that prevent it from being used by ImageMagick safely, the update for Ubuntu 18.10 and Ubuntu 19.04 includes a default policy change that disables support for the Postscript and PDF formats in ImageMagick. This policy can be overridden if necessary by using an alternate ImageMagick policy configuration. Various other issues were also addressed.
