A heap-based buffer over write vulnerability was found in GhostScript, the GPL
PostScript/PDF interpreter. An attacker could trick a user to open a crafted
PDF file, triggering the heap buffer overflow that could lead to memory
corruption or a denial of service.

9.27~dfsg-2+deb10u6.

We recommend that you upgrade your ghostscript packages.
