Debian: DSA-4303-1 Critical: Okular Directory Traversal Fixed

Joran Herve discovered that the Okular document viewer was susceptible
to directory traversal via malformed .okular files (annotated document
archives), which could result in the creation of arbitrary files.

For the stable distribution (stretch), this problem has been fixed in
version 4:16.08.2-1+deb9u1.

We recommend that you upgrade your okular packages.
