Amazon Linux 2022 : ghostscript (ALAS2022-2022-230)

medium Nessus Plugin ID 168560

Language:

Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

The version of ghostscript installed on the remote host is prior to 9.56.1-5. It is, therefore, affected by a vulnerability as referenced in the ALAS2022-2022-230 advisory.

 - A NULL pointer dereference vulnerability was found in Ghostscript, which occurs when it tries to render a large number of bits in memory. When allocating a buffer device, it relies on an init_device_procs defined for the device that uses it as a prototype that depends upon the number of bits per pixel. For bpp > 64, mem_x_device is used and does not have an init_device_procs defined. This flaw allows an attacker to parse a large number of bits (more than 64 bits per pixel), which triggers a NULL pointer dereference flaw, causing an application to crash. (CVE-2022-2085)

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.
