Two security vulnerabilities related to EXIF processing were discovered in ImageMagick, a suite of programs to manipulate images. CVE-2012-0247When parsing a maliciously crafted image with incorrect offset and count in the ResolutionUnit tag in EXIF IFD0, ImageMagick writes two bytes to an invalid address. CVE-2012-0248Parsing a maliciously crafted image with an IFD whose all IOP tags value offsets point to the beginning of the IFD itself results in an endless loop and a denial of service.

For the stable distribution (squeeze), these problems have been fixed in version 8:6.6.0.4-3+squeeze1. For the testing distribution (wheezy) and the unstable distribution (sid), these problems have been fixed in version 8:6.6.9.7-6. We recommend that you upgrade your imagemagick packages.

ImageMagick is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bzier curves. All manipulations can be achieved through shell commands as well as through an X11 graphical interface (display).
