  20.   Updated ImageMagick packages that fixes a buffer overflow are now available.    
  21.                                                                                   
  22.   ImageMagick(TM) is an image display and manipulation tool for the X Window

  25.   A buffer overflow flaw was discovered in the ImageMagick image handler.         
  26.   An attacker could create a carefully crafted image file with an improper        
  27.   EXIF information in such a way that it would cause ImageMagick to execute       
  28.   arbitrary code when processing the image. The Common Vulnerabilities and        
  29.   Exposures project (cve.mitre.org) has assigned the name CAN-2004-0981 to        
  30.   this issue.                                                                     
  31.                                                                                   
  32.   David Eisenstein has reported that our previous fix for CAN-2004-0827, a        
  33.   heap overflow flaw, was incomplete. An attacker could create a carefully        
  34.   crafted BMP file in such a way that it could cause ImageMagick to execute       
  35.   arbitrary code when processing the image. The Common Vulnerabilities and

  38.                                                                                   
  39.   Users of ImageMagick should upgrade to these updated packages, which            
  40.   contain a backported patch, and is not vulnerable to this issue.
