Low 3.9
In plain English
A low-severity security flaw in ImageMagick from ImageMagick. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.1% (higher than 1% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
ImageMagick before 7.1.2-32 and 6.9.13-57 contains a policy bypass vulnerability in LoadPolicyCache that silently skips security policy rules when policy.xml uses an alternate DOCTYPE. A valid DOCTYPE not ending in ']>' makes the parser consume the rest of the file, so no policy rules are applied and restricted operations become allowed.
