Background ========== Okular is a universal document viewer based on KPDF. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 kde-apps/okular < 19.12.3-r1 >= 19.12.3-r1 Description =========== A logic error was discovered in Okular, which results in trusting action links within a PDF, possibly allowing execution of a binary. Impact ====== A remote attacker could entice a user to open a specially crafted PDF using Okular, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition. Workaround ========== Avoid opening PDFs from an untrusted source.
