New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote EulerOS Virtualization host is missing multiple security updates.
DescriptionAccording to the versions of the ghostscript package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :
- The set_text_distance function in devices/vector/gdevpdts.c in the pdfwrite component in Artifex Ghostscript through 9.22 does not prevent overflows in text-positioning calculation, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document.i1/4^CVE-2018-10194i1/4%0
- It was discovered that the type of the LockDistillerParams parameter is not properly verified.
An attacker could possibly exploit this to bypass the
-dSAFER protection and crash ghostscript or, possibly, execute arbitrary code in the ghostscript context via a specially crafted PostScript document.i1/4^CVE-2018-15910i1/4%0
- It was discovered that the ghostscript /invalidaccess checks fail under certain conditions. An attacker could possibly exploit this to bypass the -dSAFER protection and, for example, execute arbitrary shell commands via a specially crafted PostScript document.i1/4^CVE-2018-16509i1/4%0
- It was discovered that ghostscript did not properly handle certain stack overflow error conditions. An attacker could possibly exploit this to bypass the
-dSAFER protection and crash ghostscript or, possibly, execute arbitrary code in the ghostscript context via a specially crafted PostScript document.i1/4^CVE-2018-16542i1/4%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.
