    Debian Bug     : 1140176

    Multiple security vulnerabilities were discovered in imagemagick, a
    software suite used for editing and manipulating digital images, which
    could lead to denial of service, information disclosure or potentially
    arbitrary code execution if malformed images are processed.

    For Debian 11 bullseye, these problems have been fixed in version
    8:6.9.11.60+dfsg-1.3+deb11u14.

    For Debian 12 bookworm, these problems have been fixed in version
    8:6.9.11.60+dfsg-1.6+deb12u11.

    We recommend that you upgrade your imagemagick packages.

    For the detailed security status of imagemagick please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/imagemagick
