Amazon Linux 2 : ghostscript (ALAS-2023-2308)

medium Nessus Plugin ID 183479

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of ghostscript installed on the remote host is prior to 9.25-5. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2308 advisory.

 A buffer overflow vulnerability in epsc_print_page() in devices/gdevepsc.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51. (CVE-2020-16294)

 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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update ghostscript' to update your system.
