ImageMagick 7.1.0-49 is vulnerable to Information Disclosure. When it parses a PNG image (e.g., for resize), the resulting image could have embedded the content of an arbitrary. file (if the magick binary has permissions to read it).
An information disclosure vulnerability was found in ImageMagick. This flaw allows an attacker to read arbitrary files from a server when parsing an image and happens when the program is parsing a PNG image. If ImageMagick has permission to read other arbitrary files, the resulting image could have been embedded with contents from another file on the machine after the parsing process.
Меры по смягчению последствий
To mitigate the issue, we recommend setting a security policy that is suitable for your local environment. Add this to your security policy (policy.xml):
With above policy, you get:
This can be as draconian as needed. Use /* as the path to prevent reading any file with an absolute path. You can also protect against relative paths:
