According to the versions of the ghostscript package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :
psi/zdevice2.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access restrictions because available stack space is not checked when the device remains the same.i1/4^CVE-2018-19475i1/4%0
psi/zicc.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access restrictions because of a setcolorspace type confusion.i1/4^CVE-2018-19476i1/4%0
psi/zfjbig2.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access restrictions because of a JBIG2Decode type confusion.i1/4^CVE-2018-19477i1/4%0
It was found that ghostscript could leak sensitive operators on the operand stack when a pseudo-operator pushes a subroutine. A specially crafted PostScript file could use this flaw to escape the -dSAFER protection in order to, for example, have access to the file system outside of the SAFER constraints.i1/4^CVE-2019-6116i1/4%0
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
