ImageMagick is a collection of tools and libraries for manipulating various image formats.
Two vulnerabilities have been found in ImageMagick:
A remote attacker could entice a user to open a specially crafted image, possibly resulting in execution of arbitrary code or a Denial of Service condition.
There is no known workaround at this time.
All ImageMagick users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.7.5.3"
