Amazon Linux 2023 : ghostscript, ghostscript-gtk, ghostscript-tools-dvipdf (ALAS2023-2023-296)

medium Nessus Plugin ID 180120

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-296 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)

- A buffer overflow flaw was found in base/gdevdevn.c:1973 in devn_pcx_write_rle() in ghostscript. This issue may allow a local attacker to cause a denial of service via outputting a crafted PDF file for a DEVN device with gs. (CVE-2023-38559)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update ghostscript --releasever 2023.1.20230823' to update your system.
