    Multiple security issues were discovered in Ghostscript, the GPL     PostScript/PDF interpreter, which could result in denial of service and     potentially the execution of arbitrary code if malformed document files     are processed.

    For the stable distribution (bookworm), these problems have been fixed in     version 10.0.0~dfsg-11+deb12u7.

    We recommend that you upgrade your ghostscript packages.
