EulerOS Virtualization 2.5.4 : ghostscript (EulerOS-SA-2019-1202)

Medium Nessus Plugin ID 123888

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the ghostscript package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- It was discovered that the ghostscript did not properly restrict access to files open prior to enabling the
-dSAFER mode. An attacker could possibly exploit this to bypass the -dSAFER protection and disclose the content of affected files via a specially crafted PostScript document.(CVE-2018-16539)

- It was discovered that the ghostscript device cleanup did not properly handle devices replaced with a null device. 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.(CVE-2018-16541)

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.

Solution

Update the affected ghostscript packages.
