A security issue affects the following Ubuntu releases:

The following packages are affected:
The problem can be corrected by upgrading the affected package to
version 5:126.96.36.199-1ubuntu1.4. In general, a standard system upgrade is

ImageMagick is also commonly used by web frontends; if these accept image
uploads with arbitrary file names, this could also lead to remote privilege
