| ImageMagick is a collection of tools and libraries for manipulating |
| various image formats. |

| regenrecht reported multiple infinite loops in functions ReadDCMImage() |
| and ReadXCFImage() (CVE-2007-4985), multiple integer overflows when |
| handling certain types of images (CVE-2007-4986, CVE-2007-4988), and an |
| off-by-one error in the ReadBlobString() function (CVE-2007-4987). |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| A remote attacker could entice a user to open a specially crafted |
| image, possibly resulting in the remote execution of arbitrary code |
| with the privileges of the user running the application, or an |
| excessive CPU consumption. Note that applications relying on |
| ImageMagick to process images can also trigger the vulnerability. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All ImageMagick users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.3.5.10"</code> |
| </resolution> |
