Amazon Linux 2 : ghostscript (ALAS-2024-2469)

critical Nessus Plugin ID 190707

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 a vulnerability as referenced in the ALAS2-2024-2469 advisory.

 Artifex Ghostscript before 9.53.0 has an out-of-bounds write and use-after-free in devices/vector/gdevtxtw.c (for txtwrite) because a single character code in a PDF document can map to more than one Unicode code point (e.g., for a ligature). (CVE-2020-36773)

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

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.
