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 (buster), these problems have been fixed in
version 9.27~dfsg-2+deb10u4.

We recommend that you upgrade your ghostscript packages.
