    Synopsis
    ========
    
    A flaw in Haml allows arbitrary code execution as a result of improper
    filtering.
    
    Background
    ==========
    
    Haml is a templating engine for HTML.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1  dev-ruby/haml                < 5.1.2                    >= 5.1.2
    
    Description
    ===========
    
    It was discovered that Haml was not correctly filtering out special
    characters which may be used for attributes.
    
    Impact
    ======
    
    A remote attacker could possibly execute arbitrary code with the
    privileges of the process or cause a Denial of Service condition.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All Haml users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-ruby/haml-5.1.2"
