    Synopsis
    ========
    
    A logic error in Okular might allow an attacker to execute arbitrary
    code.
    
    Background
    ==========
    
    Okular is a universal document viewer based on KPDF.
    
    Affected packages
    =================

      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.
    
    Resolution
    ==========
    
    All Okular users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=kde-apps/okular-19.12.3-r1"
