Author: tcberner Date: Fri Mar 13 05:39:11 2020 New Revision: 528330 URL: https://svnweb.freebsd.org/changeset/ports/528330 Log: Document security issue in graphics/okular https://kde.org/info/security/advisory-20200312-1.txt: Overview ======== Okular can be tricked into executing local binaries via specially crafted PDF files. This binary execution can require almost no user interaction. No parameters can be passed to those local binaries. We have not been able to identify any binary that will cause actual damage, be it in the hardware or software level, when run without parameters. We remain relatively confident that for this issue to do any actual damage, it has to run a binary specially crafted. That binary must have been deployed to the user system via another method, be it the user downloading it directly as an email attachment, webpage download, etc. or by the system being already compromised. Solution ======== - Update to Okular >= 1.10.0 - or apply the following patch: https://invent.kde.org/kde/okular/-/commit/6a93a033b4f9248b3cd4d04689b8391df754e244 Workaround ========== There's no real workaround other than not opening PDF files from untrusted sources. Credits ======= Thanks to Mickael Karatekin from Sysdream Labs for the discovery and to Albert Astals Cid for the fix.
