Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3582 advisory.

- A divide by zero issue discovered in eps_print_page in gdevepsn.c in Artifex Software GhostScript 9.50 allows remote attackers to cause a denial of service via opening of crafted PDF file. (CVE-2020-21710)

- Buffer Overflow vulnerability in clj_media_size function in devices/gdevclj.c in Artifex Ghostscript 9.50 allows remote attackers to cause a denial of service or other unspecified impact(s) via opening of crafted PDF document. (CVE-2020-21890)
