    Brad Hill of iSEC Partners discovered that many XML implementations are
    vulnerable to external entity expansion issues, which can be used for
    various purposes such as firewall circumvention, disguising an IP
    address, and denial-of-service.  libxml2 was susceptible to these
    problems when performing string substitution during entity expansion.
    
    For the stable distribution (squeeze), these problems have been fixed in
    version 2.7.8.dfsg-2+squeeze7.
    
    For the testing (wheezy) and unstable (sid) distributions, these problems
    have been fixed in version 2.8.0+dfsg1-7+nmu1.
    
    We recommend that you upgrade your libxml2 packages.
