    security/vuxml: document vulnerability in expat < 2.4.9
    
    Rhodri James discovered a heap use-after-free vulnerability in the
    doContent function in Expat, an XML parsing C library, which could
    result in denial of service or potentially the execution of arbitrary
    code, if a malformed XML file is processed.
