Description:
Several vulnerabilities were reported in ImageMagick. A remote user can cause arbitrary code to be executed on the target user's system.
A remote user can create a specially crafted DCM, DIB, XBM, XCF, or XWD image file that, when loaded by the target user or application, will trigger an integer overflow, heap overflow, or off-by-one bug and execute arbitrary code on the target system. The code will run with the privileges of the target user.
A remote user can also cause the target application to consume all available CPU resources.
