Synopsis

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

Description

The version of ghostscript installed on the remote host is prior to 8.70-24.27. It is, therefore, affected by a vulnerability as referenced in the ALAS-2023-1725 advisory.

 - A heap-based buffer over write vulnerability was found in GhostScript's lp8000_print_page() function in gdevlp8k.c file. An attacker could trick a user to open a crafted PDF file, triggering the heap buffer overflow that could lead to memory corruption or a denial of service. (CVE-2020-27792)

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

Solution

Run 'yum update ghostscript' to update your system.
