medium Nessus Plugin ID 127274

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has ghostscript packages installed that are affected by multiple vulnerabilities:

- It was found that the forceput operator could be extracted from the DefineResource method. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER. (CVE-2019-3838)

- It was found that the superexec operator was available in the internal dictionary. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER. (CVE-2019-3835)

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

Solution

Upgrade the vulnerable CGSL ghostscript packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
