CVE-2017-9835 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.69% chance of exploitation in the next 30 days.
