    Synopsis
    ========
    
    A vulnerability in file could result in Denial of Service.
    
    Background
    ==========
    
    file is a utility that guesses a file format by scanning binary data
    for patterns.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1   sys-apps/file                < 5.15 >= 5.15
    
    Description
    ===========
    
    BEGIN regular expression in the awk script detector in
    magic/Magdir/commands uses multiple wildcards with unlimited
    repetitions.
    
    Impact
    ======
    
    A context-dependent attacker could entice a user to open a specially
    crafted file, possibly resulting in a Denial of Service condition.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All file users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">= sys-apps/file-5.15"
