| <p> |
| ImageMagick is a collection of tools allowing various manipulations on |
| image files. |
| </p> |

| <description> |
| <p> |
| iDefense Labs has discovered multiple integer overflows in ImageMagick |
| in the functions ReadDCMImage() and ReadXWDImage(), that are used to |
| process DCM and XWD files. |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| An attacker could entice a user to open specially crafted XWD or DCM |
| file, resulting in heap-based buffer overflows and possibly the |
| execution of arbitrary code with the privileges of the user running |
| ImageMagick. Note that this user may be httpd or any other account used |
| by applications relying on the ImageMagick tools to automatically |
| process images. |
| </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-6.3.3"</code> |
