CVE-2017-9835 (opens in a new tab)How to fix?
Upgrade Debian:11 ghostscript to version 9.22~dfsg-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ghostscript package and not the ghostscript package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
The gs_alloc_ref_array function in psi/ialloc.c in Artifex Ghostscript 9.21 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted PostScript document. This is related to a lack of an integer overflow check in base/gsalloc.c.
