Package : ghostscript
Version : 9.06~dfsg-2+deb8u9
CVE ID : CVE-2018-16543 CVE-2018-17183
Debian Bug : 908303
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.
