    Synopsis
    ========
    
    Multiple vulnerabilities have been found in libxls, the worst of which
    could result in the arbitrary execution of code.
    
    Background
    ==========
    
    libxls is a C library for reading Excel files in the nasty old binary
    OLE format, plus a command-line tool for converting XLS to CSV.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------

    Description
    ===========
    
    Multiple vulnerabilities have been discovered in libxls. Please review
    the CVE identifiers referenced below for details.
    
    Impact
    ======
    
    A remote attacker could entice a user to process a specially crafted
    Excel file using libxls, 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
    ==========

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/libxls-1.5.2"
