Critical flaws in ImageMagick library expose websites to hacking
A tool used by millions of websites to process images has several critical vulnerabilities that could allow attackers to compromise Web servers. To make things worse, there's no official patch yet and exploits are already available.
The vulnerabilities were discovered by Nikolay Ermishkin from the Mail.Ru security team and were reported to the ImageMagick developers who attempted a fix in version 6.9.3-9, released on April 30. However, the fix is incomplete and the vulnerabilities can still be exploited.

The flaws can be exploited by uploading specially crafted images to Web applications that rely on ImageMagick to process them.
