"According to the versions of the ghostscript packages installed, the EulerOS installation on the remote host is affected
by the following vulnerabilities :
- In Artifex Ghostscript through 10.01.2, gdevijs.c in GhostPDL can lead to remote code execution via
crafted PostScript documents because they can switch to the IJS device, or change the IjsServer parameter,
after SAFER has been activated. NOTE: it is a documented risk that the IJS server can be specified on a gs
command line (the IJS device inherently must execute a command to start the IJS server). (CVE-2023-43115)
