Debian: DSA-4288-1: ghostscript security update
Summary
Tavis Ormandy discovered multiple vulnerabilites 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).
For the stable distribution (stretch), these problems have been fixed in
version 9.20~dfsg-3.2+deb9u4.
We recommend that you upgrade your ghostscript packages.
For the detailed security status of ghostscript please refer to
its security tracker page at:
