    Debian Bug     : 1147176 1149974 1150224 1150337

    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.

    Also note that this release fixes a regression where converting an SVG
    with an embedded PNG data URI to PNG fails.

    For Debian 12 bookworm, these problems have been fixed in version
    8:6.9.11.60+dfsg-1.6+deb12u14.

    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
