Amazon Linux AMI : ghostscript (ALAS-2023-1734)

critical Nessus Plugin ID 175089

Language:

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 8.70-24.28. It is, therefore, affected by a vulnerability as referenced in the ALAS-2023-1734 advisory.

In Artifex Ghostscript through 10.01.0, there is a buffer overflow leading to potential corruption of data internal to the PostScript interpreter, in base/sbcp.c. This affects BCPEncode, BCPDecode, TBCPEncode, and TBCPDecode. If the write buffer is filled to one byte less than full, and one then tries to write an escaped character, two bytes are written. (CVE-2023-28879)

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.
