For the oldstable distribution (bullseye), this problem has been fixed in version 9.53.3~dfsg-7+deb11u5.

For the stable distribution (bookworm), this problem has been fixed in version 10.0.0~dfsg-11+deb12u1.

We recommend that you upgrade your ghostscript packages.

For the detailed security status of ghostscript please refer to its security tracker page at: [link moved to references]");
