ghostscript

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 908303.
In Mitre's CVE dictionary: CVE-2018-16543, CVE-2018-17183.

More information:

Tavis Ormandy discovered multiple vulnerabilities in Ghostscript, an interpreter for the PostScript language, which could result in denial of service, the creation of files or the execution of arbitrary code if a malformed Postscript file is processed (despite the dSAFER sandbox being enabled).

In addition this update changes the device to txtwrite for the ps2ascii tool to prevent an error due to the fix for CVE-2018-17183.

For Debian 8 Jessie, these problems have been fixed in version 9.06~dfsg-2+deb8u9.

We recommend that you upgrade your ghostscript packages.
