    Synopsis
    ========
    
    Ark was found to allow arbitrary file overwrite, possibly allowing
    arbitrary code execution.
    
    Background
    ==========
    
    Ark is a graphical file compression/decompression utility with support
    for multiple formats.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1  kde-apps/ark               < 20.04.3-r2            >= 20.04.3-r2
    
    Description
    ===========
    
    It was discovered that Ark incorrectly handled symbolic links in tar
    archive files.
    
    Impact
    ======
    
    A remote attacker could entice a user to open a specially crafted
    archive using Ark, possibly resulting in execution of arbitrary code
    with the privileges of the process or a Denial of Service condition.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All KDE Ark users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=kde-apps/ark-20.04.3-r2"
